The Invasion of Grenada was a 1983 United States–led invasion of the Caribbean island nation of Grenada, with a population of about 91,000 located 160 kilometres (99 mi) north of Venezuela, that resulted in a U.S. victory within a matter of weeks. Codenamed Operation Urgent Fury, it was triggered by the house arrest on 12 October 1983 and murder of the leader (19 October 1983) of the coup which had brought a revolutionary government to power for the preceding four years. The invasion resulted in the appointment of an interim government, followed by democratic elections in 1984.
Grenada gained independence from the United Kingdom in 1974. The leftist New Jewel Movement seized power in a coup in 1979, suspending the constitution. After a 1983 internal power struggle ended with the deposition and murder of revolutionary prime minister Maurice Bishop, the invasion began early on 25 October 1983.
The U.S. Army's Rapid Deployment Force (1st, 2nd Ranger Battalions and 82nd Airborne Division Paratroopers), U.S. Marines, U.S. Army Delta Force, and U.S. Navy SEALs and other combined forces constituted the 7,600 troops from the United States, Jamaica, and members of the Regional Security System (RSS) defeated Grenadian resistance after a low-altitude airborne assault by the 75th Rangers on Point Salines Airport on the southern end of the island, and a Marine helicopter and amphibious landing occurred on the northern end at Pearl's Airfield shortly afterward. The military government of Hudson Austin was deposed and replaced by a government appointed by Governor-General Paul Scoon until elections were held in 1984.
The invasion was highly criticized by a number of prominent countries including the United Kingdom and Canada, as well as the United Nations General Assembly, which on 2 November 1983 with a vote of 108 to 9 condemned it as "a flagrant violation of international law". Conversely, it was reported to have enjoyed broad public support in the United States as well as some sectors in Grenada from local groups who viewed the 4 year post-coup regime as illegitimate. The U.S. awarded more than 5,000 medals for merit and valor.
The date of the invasion is now a national holiday in Grenada, called Thanksgiving Day. For many Grenadians[weasel words], the Grenada Revolution died with Bishop and so they gave thanks when the US rescued them from the faction which killed Bishop. The Point Salines International Airport was renamed in honor of Prime Minister Maurice Bishop on the 65th anniversary of his birth on 29 May 2009. Hundreds of Grenadians turned out to commemorate the historical event. Prime Minister of St Vincent and the Grenadines and close friend of Bishop gave the key note speech and referred to the renaming as an act of the Grenadian people coming home to themselves. He also hoped that it will help bring closure to a chapter of denial in Grenada's history. The invasion also highlighted problematic issues with communication and coordination between the different branches of the United States military when operating together as a joint force, contributing to investigations and sweeping changes in the form of the Goldwater-Nichols Act and other reorganizations.

Sir Eric Gairy had led Grenada to independence from the United Kingdom in 1974. His term in office coincided with civil strife in Grenada. The political environment was highly charged and although Gairy—head of the Grenada United Labour Party—claimed victory in the general election of 1976, the opposition did not accept the result as legitimate. The civil strife took the form of street violence between Gairy's private army, the Mongoose Gang, and gangs organized by the New Jewel Movement (NJM). In the late 1970s the NJM began planning to overthrow the government. Party members began to receive military training outside of Grenada. On 13 March 1979, while Gairy was out of the country, the NJM—led by Maurice Bishop—launched an armed revolution and overthrew the government, establishing the People's Revolutionary Government.
On 16 October 1983, a party faction led by Deputy Prime Minister Bernard Coard seized power. Bishop was placed under house arrest. Mass protests against the action led to Bishop's escaping detention and reasserting his authority as the head of the government. Bishop was eventually captured and murdered along with several government officials loyal to him. The army under Hudson Austin then stepped in and formed a military council to rule the country. The governor-general, Paul Scoon, was placed under house arrest. The army announced a four-day total curfew where anyone seen on the streets would be subject to summary execution.
The Organization of Eastern Caribbean States (OECS), as well as the nations of Barbados and Jamaica, appealed to the United States for assistance. It was later announced that Grenada's governor-general, Paul Scoon, had actually requested the invasion through secret diplomatic channels and for his safety it had not been made public. Scoon was well within his rights to take this action under the reserve powers vested in the Crown. On Saturday 22 October 1983, the Deputy High Commissioner in Bridgetown, Barbados visited Grenada and reported that Sir Paul Scoon was well and "did not request military intervention, either directly or indirectly".
On 25 October, Grenada was invaded by the combined forces of the United States and the Regional Security System (RSS) based in Barbados, in an operation codenamed Operation Urgent Fury. The U.S. stated this was done at the request of the prime ministers of Barbados and Dominica, Tom Adams and Dame Eugenia Charles, respectively. Nonetheless, the invasion was highly criticized by the governments in Canada, Trinidad and Tobago, and the United Kingdom. The United Nations General Assembly condemned it as "a flagrant violation of international law" by a vote of 108 in favour to 9, with 27 abstentions. The United Nations Security Council considered a similar resolution, which failed to pass when vetoed by the United States.
The Bishop government began constructing the Point Salines International Airport with the help of Britain, Cuba, Libya, Algeria, and other nations. The airport had been first proposed by the British government in 1954, when Grenada was still a British colony. It had been designed by Canadians, underwritten by the British government, and partly built by a London firm. The U.S. government accused Grenada of constructing facilities to aid a Soviet-Cuban military buildup in the Caribbean based upon the 9,000-foot length runway, which could accommodate the largest Soviet aircraft like the An-12, An-22, and the An-124, which would enhance the Soviet and Cuban transportation of weapons to Central American insurgents and expand Soviet regional influence. Bishop's government claimed that the airport was built to accommodate commercial aircraft carrying tourists, pointing out that such jets could not land at Pearl's Airstrip on the island's north end (5,200 feet) and could not be expanded because its runway abutted a mountain at one end and the ocean at the other.
In 1983, then-member of the United States House of Representatives Ron Dellums (D, California), traveled to Grenada on a fact-finding mission, having been invited by the country's prime minister. Dellums described his findings before Congress:
... based on my personal observations, discussion and analysis of the new international airport under construction in Grenada, it is my conclusion that this project is specifically now and has always been for the purpose of economic development and is not for military use. ... It is my thought that it is absurd, patronizing, and totally unwarranted for the United States government to charge that this airport poses a military threat to the United States' national security.
In March 1983, President Ronald Reagan began issuing warnings about the threat posed to the United States and the Caribbean by the "Soviet-Cuban militarization" of the Caribbean as evidenced by the excessively long airplane runway being built, as well as intelligence sources indicating increased Soviet interest in the island. He said that the 9,000-foot (2,700 m) runway and the numerous fuel storage tanks were unnecessary for commercial flights, and that evidence pointed that the airport was to become a Cuban-Soviet forward military airbase.
On 29 May 2009 the Point Salines International Airport was officially renamed the Maurice Bishop International Airport, in honour of the slain pre-coup leader Maurice Bishop by the Government of Grenada.
First day of the invasion
The invasion commenced at 05:00 on 25 October 1983. American forces refuelled and departed from the Grantley Adams International Airport on the nearby Caribbean island of Barbados before daybreak en route to Grenada. It was the first major operation conducted by the U.S. military since the Vietnam War. Vice Admiral Joseph Metcalf, III, Commander Second Fleet, was the overall commander of U.S. forces, designated Joint Task Force 120, which included elements of each military service and multiple special operations units. Fighting continued for several days and the total number of U.S. troops reached some 7,000 along with 300 troops from the OAS. The invading forces encountered about 1,500 Grenadian soldiers and about 700 Cubans. The Grenada forces includes eight BTR-60PB APCs, two BRDM-2 scout cars, twelve ZU-23 23mm and additional quad DShK 12.7mm anti-craft guns, and a limited number of 82mm mortars and rocket propelled grenade launchers.
The main objectives on the first day of the invasion were the capture of the Point Salines International Airport by the 75th Ranger Regiment, to permit the 82nd Airborne Division to land reinforcements on the island; the capture of Pearls Airport by the 8th Marine Regiment; and the rescue of the U.S. students at the True Blue Campus of St. George's University. In addition, a number of special operations missions were undertaken to obtain intelligence and secure key individuals and equipment. In general, many of these mission were plagued by inadequate intelligence, planning, and accurate maps of any kind (the American forces mostly relied upon tourist maps).
Cuban forces in Grenada
The nature of the Cuban military presence in Grenada was more complex than initially suggested. As in Angola, Ethiopia, and other nations with large contingents of Cuban troops, the line between civilians and military personnel was blurred. For example, Fidel Castro often described Cuban construction crews deployed overseas as "workers and soldiers at the same time"; the duality of their role being consistent with Havana's 'citizen soldier' tradition. According to journalist Bob Woodward in his book Veil, captured "military advisers" from the aforementioned countries were actually accredited diplomats and included their dependents. None took any actual part in the fighting. Other historians have asserted that most of the supposed civil technicians on Grenada were Cuban special forces and combat engineers.
U.S. Special operations were deployed to Grenada starting on October 23, before the invasion on October 25. U.S. Navy Seals from SEAL Team 6 were airdropped at sea with inflatable boats to perform a reconnaissance mission on Point Salines, but stormy weather caused 4 of them to drown upon landing. The motor on the boat used by the survivors flooded while evading a patrol boat, causing the mission to be aborted. A SEAL mission on the 24th also was made unsuccessful due to harsh weather, resulting in little intelligence being gathered on the focal point of the impending U.S. intervention.
Air-Landing at Point Salines
At midnight on October 24, the A and B companies of the 1st Battalion of the 75th Ranger Regiment embarked on C-130s at Hunter Army Airfield to perform an air assault landing on Point Salines International Airport. Initially intending to land at the airport and then disembark, the Rangers had to switch abruptly to a parachute landing when it was learned mid-flight that the runway was obstructed. The air drop began at 5:30 AM on the 25th in the face of moderate resistance from ZU-23 anti-aircraft guns and several BTR-60 APCs, the latter of which were knocked out by 90mm recoilless rifles. AC-130 gunships also provided support for the landing. Cuban construction vehicles were commandeered to help clear the airfield, and one was even used to provide mobile cover for the Rangers as they moved to seize the heights surrounding the airfield.
By 10 AM, the air strip had been cleared of obstructions and transport planes were able to land directly and unload additional reinforcements, including M151 Jeeps and elements of the Caribbean Peace Force, which were assigned to guard the perimeter and detainees. Starting at 2 PM, units from the 82nd Airborne Division began landing at Point Salines, including battalions of the 325th Infantry Regiment. At 3:30 PM, a counterattack by 3 BTR-60s of the Grenadian Army Motorized Company was destroyed with fire from recoilless rifles and an AC-130.
The Rangers proceeded to fan out and secure the surrounding area, including negotiating the surrender of over a hundred Cubans in an aviation hangar. However, a jeep-mounted Ranger patrol became lost searching for True Blue Campus and was ambushed, suffering 4 KIA. The Rangers eventually secured True Blue campus and its students, where they were shocked to discover only 140 students, and were told that more were located at another campus in Anse. In all, the Rangers lost 5 men on the first day, but succeeded in securing the Point Salines and the surrounding area.
Capture of Pearls Airport
Close to midnight on October 24, SEAL Team 4 under Lieutenant Mike Walsh approached the beach near Pearls Airport, evading patrol boats and overcoming stormy weather, and determined that the beach was undefended but unsuitable for an amphibious landing. The 2nd Battalion of the 8th Marine Regiment then landed south of Pearls Airport using CH-46 Sea Knight and CH-53 Sea Stallion helicopters at 5:30 AM on the 25th. They proceeded to capture Pearl Airport, encountering only light resistance, including a DShK machine gun which was destroyed by a Marine AH-1 Cobra.
Raid on Radio Free Grenada
On the early morning of the 25th, another team from SEAL Team 6 was inserted by UH-60 Blackhawk helicopters to capture Radio Free Grenada, in order to use it for PsyOps purposes. Although the station was captured unopposed, a counter-attack including BTR-40 armored cars forced the lightly-armed SEALs to retreat in the jungle, destroying the radio transmitter as they left.
Raids on Fort Rupert and Richmond Hill Prison
On the October 25, raids were undertaken by Delta Force and C Company of the 75th Ranger Regiment, embarked upon MH-60 and MH-6 Little Bird helicopters of Task Force 160 to capture Fort Ruppert, where the leadership of the Revolutionary Council was believed to reside, and Richmond Hill Prison, where many political prisoners were being held. The raid on Richmond Hill Prison lacked vital intelligence, including the fact that multiple anti-aircraft guns were located around and above the prison, and that the prison was located on a steep hill without room for a helicopter to land. Withering anti-craft fire wounded passengers and crew, and forced one MH-60 helicopter to crash land, causing another helicopter to land next to it to protect the survivors. One pilot was killed, and the Delta force operators had to be relieved by a separate force of Rangers. The raid on Fort Rupert, however, was successful in capturing several leaders of the People's Revolutionary Government.
Mission to rescue Governor General Scoon
The last major special operation was a mission to rescue and evacuate Governor General Paul Scoon from his mansion in Saint George, Grenada. The mission departed late at 5:30 AM on October 25 from Barbados, resulting in the Grenadian forces being already aware of the U.S. invasion when it landed and secured Governor Scoon. Although the SEAL team's entry into the mansion went unopposed, a large local counterattack including BTR-60 APCs trapped the SEALs and the governor inside. AC-130 gunships, A-7 Corsair strike planes, and AH-1 Cobra attack helicopters were called in to support the besieged SEALs, but the SEALs remained trapped for the next 24 hours.
At 7 PM on October 25, 250 U.S. Marines from G Company of the 22nd Marine Assault Unit equipped with Amphibious Assault Vehicles and four M60 Patton tanks landed at Grand Mal Bay, and relieved the Navy SEALs the following morning on October 26, allowing Governor Scoon, his wife and nine aides to be safely evacuated at 10 AM that day. G Company then proceeded to capture Fort Frederick.
Airstrikes were undertaken by U.S. Navy A-7 Corsairs as well as U.S. Marine AH-1 Cobra attack helicopters against Fort Rupert and Fort Frederick. An A-7 raid on Fort Frederick targeting anti-aircraft guns hit a nearby mental hospital, killing 18 civilians.:62 Two Marine AH-1T Cobras and a UH-60 Blackhawk were shot down in a raid against Fort Frederick, resulting in five KIA.
Second day of the invasion
On the second day, U.S. Commander on the ground, General Trobaugh of the 82nd Airborne Division, had two goals: securing the perimeter around Salines Airport and rescuing the U.S. students they had learned were at the campus in Anse. Because of the lack of undamaged helicopters after the losses on the first day, the Army had to delay pursuing the second objective until it made contact with Marine forces.
Attack on the Cuban compound
Early in the morning of the 26th, a patrol from the 2nd Battalion of the 325th Infantry Regiment was ambushed by Cuban forces near the village of Calliste, suffering six wounded and two killed in the ensuing firefight including the commander of Company B. Following that, U.S. Navy air strikes and an artillery bombardment by 105mm howitzers targeting the main Cuban encampment eventually lead to their surrender at 8:30. US forces pushed on into the village of Frequente, where they discovered a Cuban weapon cache supposedly sufficient to equip "six battalions." There, a reconnaissance platoon mounted of gun-jeeps was ambushed by Cuban forces, but return fire from the jeeps, and mortars from a nearby infantry unit inflicted four casualties on the ambushers at no U.S. loss. Cuban resistance largely ended after these engagements.
'Rescue' at Grand Anse
In the afternoon of the 26, US Rangers of the 2nd Battalion of the Ranger Regiment mounted U.S. Marine CH-46 Sea Knight helicopters to launch an air assault on the Anse campus. The campus guards offered light resistance before fleeing, wounding one Ranger, but one of the helicopters crashed on the approach after its blade hit a palm tree. The 233 U.S. students present were successfully evacuated into CH-53 Sea Stallion helicopters, but informed the U.S. commanders that there was a third campus with U.S. students at Prickly Bay. A squad of 11 Rangers was accidentally left behind, ultimately egressing on a rubber raft which was picked up by the USS Caron at 11 PM.
Third day of the invasion and after
By October 27, organized resistance was rapidly diminishing, but the American forces did not yet realize this. The Marine 22nd MAU and 8th Regiment continued advancing along the coast and capturing additional towns, meeting little resistance, although a Jeep patrol did bump into a BTR-60 during the night and knocked it out with a LAW. The 325th Infantry Regiment advanced toward Saint George, capturing Grand Anse (where they discovered 20 U.S. students they had missed the first day), the town of Ruth Howard, and the capital of Saint George, meeting only scattered resistance. An A-7 airstrike called by an Air-Naval Gunfire Liaison team accidentally hit the command post of the 2nd Brigade, wounding 17 troops, one of whom died of wounds.
The Army had reports that PRA forces were amassing at the Calivigny barracks, only five kilometers miles away from the Point Salines airfield. They therefore organized an air assault by the 2nd Battalion of the 75th Ranger Regiment which would be preceded by a heavy preparatory bombardment by field howitzers (which mostly missed, their shells falling into ocean), A-7 Corsairs, AC-130s, and the USS Caron. However, when the Blackhawk helicopters began dropping off troops near the barracks, they approached at too high a speed, and one of them crash-landed and the two behind it collided into it, killing three and wounding four. Ironically, the barracks were deserted.
In the following days, resistance ended entirely and the Army and Marines spread across the island, arresting PRA officials, seizing caches of weapons, and seeing to the repatriation of Cuban engineers.
On November 1, two companies from the 22nd Marine Amphibious Unit made a combined sea and helicopter landing on the island of Carriacou 17 miles (27 km) to the northeast of Grenada. The nineteen Grenadan soldiers defending the island surrendered without a fight. This was the last military action of the campaign.
Official U.S. sources state that some of their opponents were well prepared and well positioned and put up stubborn resistance, to the extent that the U.S. called in two battalions of reinforcements on the evening of 26 October. The total naval and air superiority of the coalition forces—including helicopter gunships and naval gunfire support as well as members of reserve Navy SEALs, had overwhelmed the defenders.
Nearly 8,000 soldiers, sailors, airmen, and marines had participated in Operation Urgent Fury along with 353 Caribbean allies of the Caribbean Peace Forces. U.S. forces sustained 19 killed and 116 wounded; Cuban forces sustained 25 killed, 59 wounded, and 638 combatants captured. Grenadian forces casualties were 45 killed and 358 wounded; at least 24 civilians were killed, 18 of whom were killed in the accidental bombing of a Grenadian mental hospital.:62
Reaction in the United States
A month after the invasion, Time magazine described it as having "broad popular support." A congressional study group concluded that the invasion had been justified, as most members felt that U.S. students at the university near a contested runway could have been taken hostage as U.S. diplomats in Iran had been four years previously. The group's report caused House Speaker Tip O'Neill to change his position on the issue from opposition to support.
However, some members of the study group dissented from its findings. Congressman Louis Stokes, D-Ohio, stated: "Not a single American child nor single American national was in any way placed in danger or placed in a hostage situation prior to the invasion." The Congressional Black Caucus denounced the invasion and seven Democratic congressmen, led by Ted Weiss, introduced an unsuccessful resolution to impeach Ronald Reagan.
In the evening of 25 October 1983 by telephone, on the newscast Nightline, anchor Ted Koppel spoke to medical students on Grenada who stated that they were safe and did not feel their lives were in danger. The next evening, again by telephone, medical students told Koppel how grateful they were for the invasion and the Army Rangers, which probably saved their lives. State Department officials had assured the medical students that they would be able to complete their medical school education in the United States.
On 2 November 1983 by a vote of 108 in favour to 9 (Antigua and Barbuda, Barbados, Dominica, El Salvador, Israel, Jamaica, Saint Lucia, Saint Vincent and the Grenadines, and the United States) voting against, with 27 abstentions, the United Nations General Assembly adopted General Assembly Resolution 38/7, which "deeply deplores the armed intervention in Grenada, which constitutes a flagrant violation of international law and of the independence, sovereignty and territorial integrity of that State." It went on to deplore “the death of innocent civilians” the “killing of the prime Minister and other prominent Grenadians” and called for an “immediate cessation of the armed intervention” and demanded “that free elections be organized”.
The USSR government said that Grenada had for a long time been the object of United States threats, that the invasion violated international law, and that no small nation not to the liking of the United States would find itself safe if the aggression against Grenada was not rebuffed. The governments of some countries stated that the United States intervention was a return to the era of barbarism. The governments of other countries said the United States by its invasion had violated several treaties and conventions to which it was a party.
A similar resolution was discussed in the United Nations Security Council and although receiving widespread support it was ultimately vetoed by the United States. President of the United States Ronald Reagan, when asked if he was concerned by the lopsided 108–9 vote in the UN General Assembly said "it didn't upset my breakfast at all."
Grenada is part of the Commonwealth of Nations and, following the invasion, it requested help from other Commonwealth members. The invasion was opposed by the United Kingdom, Trinidad and Tobago, and Canada, among others.:50 British Prime Minister Margaret Thatcher personally opposed the U.S. invasion, and the British Foreign Secretary, Geoffrey Howe, announced to the British House of Commons on the day before the invasion that he had no knowledge of any possible U.S. intervention. At 12:30 am Tuesday 25 October, on the morning of the invasion, Thatcher sent a message to Reagan:
This action will be seen as intervention by a Western country in the internal affairs of a small independent nation, however unattractive its regime. I ask you to consider this in the context of our wider East/West relations and of the fact that we will be having in the next few days to present to our Parliament and people the siting of Cruise missiles in this country. I must ask you to think most carefully about these points. I cannot conceal that I am deeply disturbed by your latest communication. You asked for my advice. I have set it out and hope that even at this late stage you will take it into account before events are irrevocable. (The full text remains classified.)
When she telephoned Reagan twenty minutes later, he assured Thatcher that an invasion was not contemplated. Reagan later said, "She was very adamant and continued to insist that we cancel our landings on Grenada. I couldn't tell her that it had already begun."
In November 2014, a recorded telephone conversation between Ronald Reagan and Margaret Thatcher was published, which captured an apologetic Reagan discussing the invasion with Margaret Thatcher. In this conversation, Reagan expressed regret over any embarrassment caused due to US actions. He also cited lack of time and concerns regarding leaks as the reason for not informing her of the invasion sooner. Thatcher expressed her comprehension for the secrecy and why he had not been more open with her, saying she had been subject to similar restrictions at the time of the Falklands invasion. The publishing of this, and other, recordings also confirmed that later Presidents continued the practice of recording White House conversations after Nixon's Watergate scandal, albeit for the purpose of later assistance in transcription.
Following the U.S. victory, the American and Caribbean governments quickly reaffirmed Queen Elizabeth II as Grenada's lawful ruler, and recognized Scoon as her only lawful representative in Grenada. In accordance with Commonwealth constitutional practice, Scoon assumed power as interim head of government, and formed an advisory council which named Nicholas Brathwaite as chairman pending new elections. Democratic elections held in December 1984 were won by the Grenada National Party and a government was formed led by Prime Minister Herbert Blaize.
U.S. forces remained in Grenada after combat operations finished in December as part of Operation Island Breeze. Elements remaining, including military police, special forces, and a specialized intelligence detachment, performed security missions and assisted members of the Caribbean Peacekeeping Force and the Royal Grenadian Police Force.
The invasion showed problems with the U.S. government's "information apparatus," which Time described as still being in "some disarray" three weeks after the invasion. For example, the U.S. State Department falsely claimed that a mass grave had been discovered that held 100 bodies of islanders who had been killed by Communist forces. Major General Norman Schwarzkopf, deputy commander of the invasion force, said that 160 Grenadian soldiers and 71 Cubans had been killed during the invasion; the Pentagon had given a much lower count of 59 Cuban and Grenadian deaths. Ronald H. Cole's report for the Joint Chiefs of Staff showed an even lower count.
Also of concern were the problems that the invasion showed with the military. There was a lack of intelligence about Grenada, which exacerbated the difficulties faced by the quickly assembled invasion force. For example, it was not known that the students were actually at two different campuses and there was a thirty-hour delay in reaching students at the second campus. Maps provided to soldiers on the ground were tourist maps on which military grid reference lines were drawn by hand to report locations of units and request artillery and aircraft fire support. They also did not show topography and were not marked with crucial positions. U.S. Navy ships providing naval gunfire and U.S. Marine, U.S. Air Force and Navy fighter/bomber support aircraft providing close air support mistakenly fired upon and killed U.S. ground forces due to differences in charts and location coordinates, data, and methods of calling for fire support. Communications between services were also noted as not being compatible and hindered the coordination of operations. The landing strip was drawn-in by hand on the map given to some members of the invasion force.
A heavily fictionalized account of the invasion from a U.S. military perspective is shown in the 1986 Clint Eastwood motion picture Heartbreak Ridge, in which Marines replaced the actual roles of U.S. Army units. Due to the movie's portrayal of several incompetent officers and NCOs, the Army opted out its military support of the movie.
Analysis by the U.S. Department of Defense showed a need for improved communications and coordination between the branches of the U.S. forces. U.S. Congressional investigations of many of the reported problems resulted in the most important legislative change affecting the U.S. military organization, doctrine, career progression, and operating procedures since the end of World War II – the Goldwater-Nichols Department of Defense Reorganization Act of 1986 (Pub. L.99–433).
The Goldwater-Nichols Act reworked the command structure of the United States military, thereby making the most sweeping changes to the United States Department of Defense since the department was established in the National Security Act of 1947. It increased the powers of the Chairman of the Joint Chiefs of Staff and created the concept of a truly unified joint U.S. forces (i.e., Army, Air Force, Marines, and Navy forces organized under one command). One of the first reorganizations resulting from both the Department of Defense analysis and the legislation was the formation of the U.S. Special Operations Command in 1987.
October 25 is a national holiday in Grenada, called Thanksgiving Day, to commemorate the invasion.
In 2008, the Government of Grenada announced a move to build a monument to honour the Cubans killed during the invasion. At the time of the announcement the Cuban and Grenadian governments are still seeking to locate a suitable site for the monument.
Order of battle
Leading joint forces, Vice Admiral Joseph Metcalf, III, COMSECONDFLT, became Commander, Joint Task Force 120 (CJTF 120), and commanded units from the Air Force, Army, Navy, and the Marine Corps from the Flag Spaces aboard the aircraft carrier USS Independence. Vice Admiral Metcalf assigned to the amphibious force (on MARG flagship – USS Guam) during combat operations), designated Task Force 124, the mission of seizing the Pearls Airport and the port of Grenville, and of neutralizing any opposing forces in the area. Simultaneously, Army Rangers (Task Force 121) – together with elements of the 82d Airborne Division (Task Force 123) – would secure points at the southern end of the island, including the nearly completed jet airfield under construction near Point Salines. Task Group 20.5, a carrier battle group built around USS Independence (CV-62), and Air Force elements would support the ground forces.
