M26 grenade, issued to the U.S. Army and U.S. Marines in the Vietnam War, used in many fragging incidents.[1]

Fragging is the deliberate or attempted killing by a soldier of a fellow soldier, usually a superior. U.S. military personnel coined the word during the Vietnam War, when such killings were most often attempted with a fragmentation grenade,[2] sometimes making it appear that the killing was accidental or during combat with the enemy. The term fragging now encompasses any deliberate killing of military colleagues.[3][4]

The high number of fragging incidents in the latter years of the Vietnam War was symptomatic of the unpopularity of the war with the American public and the breakdown of discipline in the U.S. Armed Forces. Documented and suspected fragging incidents totalled nearly nine hundred from 1969 to 1972.[5]

Fragging should not be confused with the unintentional killing and/or wounding of comrades and/or allied personnel - such incidents are referred to as friendly fire.


Soldiers have killed colleagues since the beginning of armed conflict, with many documented instances throughout history. However, the practice of fragging seems to have been relatively uncommon in the U.S. military until the Vietnam War. The prevalence of fragging was partially based on the ready availability of explosive weapons such as fragmentation hand grenades. Grenades were untraceable to an owner and did not leave any ballistic evidence. M18 Claymore mines and other explosives were also occasionally used in fragging, as were firearms, although the term, as defined by the military during the Vietnam War, applied only to the use of explosives to kill fellow soldiers.[5]: 1, 19 [6] Most fragging incidents were in the Army and Marine Corps. Fragging was rare among Navy and Air Force personnel, who had less access to grenades and weapons than did soldiers and Marines.[5]: 30–31 

The first known incidents of fragging in South Vietnam took place in 1966, but events in 1968 appear to have catalyzed an increase in fragging. After the Tet Offensive in January and February 1968, the Vietnam War became increasingly unpopular in the United States and among American soldiers in Vietnam, many of them conscripts. Secondly, racial tensions between white and black soldiers and marines increased after the assassination of Martin Luther King Jr. in April 1968.[5]: 19–21  With troops reluctant to risk their lives in what was perceived as a lost war, fragging was seen by some enlisted men "as the most effective way to discourage their superiors from showing enthusiasm for combat."[6]

Morale plummeted among soldiers and marines. By 1971, a USMC colonel declared in the Armed Forces Journal that "The morale, discipline, and battle worthiness of the U.S. Armed Forces are, with a few salient exceptions, lower and worse than at any time in this century and possibly in the history of the United States."[7][8]

The U.S. military reflected social problems and issues in the U.S. such as racism, drug abuse, and resentment toward authoritarian leaders. As the U.S. began to withdraw its military forces from Vietnam, some American enlisted men and young officers lost their sense of purpose for being in Vietnam, and the hierarchical relationship between enlisted men and their officers deteriorated. The resentment directed from enlisted men toward older officers was exacerbated by generational gaps, as well as different perceptions of how the military should conduct itself. Enforcement of military regulations, especially if done overzealously, led to complaints and sometimes threats of physical violence directed toward officers.[5]

A number of factors may have influenced the incidence of fragging. The demand for manpower for the war in Vietnam caused the armed forces to lower their standards for inducting both officers and enlisted men. The rapid rotation of personnel, especially of officers who served (on average) less than six months in command roles, decreased the stability and cohesion of military units. Most important of all, perhaps, was the loss of purpose in fighting the war, as it became apparent to all that the United States was withdrawing from the war without having achieved any sort of victory. Morale and discipline deteriorated.[5]: 12–18 

Most fragging was perpetrated by enlisted men against officers. Enlisted men, in the words of one company commander, "...feared they would get stuck with a lieutenant or platoon sergeant who would want to carry out all kinds of crazy John Wayne tactics, who would use their lives in an effort to win the war single-handedly, win the big medal, and get his picture in the hometown paper."[5]: 84–85  Harassment of subordinates by a superior was another frequent motive. The stereotypical fragging incident was of "an aggressive career officer being assaulted by disillusioned subordinates." Several fragging incidents resulted from alleged racism between black and white soldiers. Attempts by officers to control drug use caused others. Most known fragging incidents were carried out by soldiers in support units rather than soldiers in combat units.[5]: 61–122 

Soldiers sometimes used non-lethal smoke and tear-gas grenades to warn superiors that they were in more serious danger if they did not change their behavior. A few instances occurred—and many more were rumored—in which enlisted men collected "bounties" on particular officers or non-commissioned officers to reward soldiers for fragging them.[5]: 25, 37–42 

U.S. Forces in Vietnam[edit]

Total 156+ 321+ 363+ 64

Note: Statistics were not kept before 1969.

According to author George Lepre, the total number of known and suspected fragging cases by explosives in Vietnam from 1969 to 1972 totalled nearly 900, with 99 deaths and many injuries. This total is incomplete, as some cases were not reported, nor were statistics kept before 1969 (although several incidents from 1966 to 1968 are known). Most of the victims or intended victims were officers or non-commissioned officers. The number of fraggings increased in 1970 and 1971 even though the U.S. military was withdrawing and the number of U.S. military personnel in Vietnam was declining.[5]: 44–47 [9]: 155 

An earlier calculation by authors Richard A. Gabriel and Paul L. Savage, estimated that up to 1,017 fragging incidents may have taken place in Vietnam, causing 86 deaths and 714 injuries of U.S. military personnel, the majority officers and NCOs.[10]

Fragging statistics include only incidents involving explosives, most commonly grenades. Several hundred murders of U.S. soldiers by firearms occurred in Vietnam but most were of enlisted men killing other enlisted men of nearly equal rank. Fewer than ten officers are known to have been murdered by firearms. However, rumors and claims abound of the deliberate killing of officers and non-commissioned officers by enlisted men under battlefield conditions. The frequency and number of these fraggings, indistinguishable from combat deaths, cannot be quantified.[5]: 26, 220–221 


The U.S. military's responses to fragging incidents included greater restrictions on access to weapons, especially grenades, for soldiers in non-combat units and post-fragging "lockdowns" in which a whole unit was isolated until after an investigation. For example, in May 1971, the U.S. Army in Vietnam temporarily halted the issuance of grenades to nearly all units and soldiers in Vietnam, inventoried stocks of weapons, and searched soldiers' quarters, confiscating weapons, ammunition, grenades, and knives. This, however, failed to reduce fragging incidents as soldiers could easily obtain weapons in a flourishing black market among nearby Vietnamese communities. The U.S. military also attempted to diminish adverse publicity concerning fragging and the security measures it was taking to reduce it.[5]: 128–142 

Only a few fraggers were identified and prosecuted. It was often difficult to distinguish between fragging and enemy action. A grenade thrown into a foxhole or tent could be a fragging, or the action of an enemy infiltrator or saboteur. Enlisted men were often close-mouthed in fragging investigations, refusing to inform on their colleagues out of fear or solidarity. Sentences for fragging convictions were severe—but the few men convicted often served fairly brief prison sentences. Ten fraggers were convicted of murder and served sentences from ten months to forty years with a mean prison time of about nine years.[5]: 140–141, 181–182, 229 


In the Vietnam War, the threat of fragging caused many officers and NCOs to go armed in rear areas and to change their sleeping arrangements as fragging often consisted of throwing a grenade into a tent where the target was sleeping. For fear of being fragged, some leaders turned a blind eye to drug use and other indiscipline among the men in their charge. Fragging, the threat of fragging, and investigations of fragging sometimes disrupted or delayed tactical combat operations. Officers were sometimes forced to negotiate with their enlisted men to obtain their consent before undertaking dangerous patrols.[5]: 175–176 

The breakdown of discipline, including fragging, was an important influence on the U.S. change to an all-volunteer military in place of conscription. The last conscript was inducted into the army in 1973.[11][12] The volunteer military moderated some of the coercive methods of discipline previously used to maintain order in military ranks.[5]: 183

  • April 21, 1969: A grenade was thrown into the company office of K Company, 9th Marines, at Quảng Trị Combat Base, RVN, with First Lieutenant Robert T. Rohweller dying of wounds he received in the explosion. Private Reginald F. Smith, who was apprehended after boasting about the killing to a colleague in formation while still having a grenade ring on his finger, pleaded guilty to the premeditated murder of Rohweller and was sentenced to 40 years' imprisonment; he was murdered by a fellow inmate in prison on 25 July 1982.[5][20][21]
  • March 15, 1971: A grenade was tossed into an officer billet at Bien Hoa Army Airfield, with Lieutenants Thomas A. Dellwo and Richard E. Harlan of the 1st Cavalry Division (Airmobile) being killed. Private Billy Dean Smith was charged with the murders of the officers but was acquitted at a court-martial in November 1972.[5]: 89–93, 51–57 

Vietnam War (Australian forces)[edit]

  • November 23, 1969: Lieutenant Robert Thomas Convery of the 9th Battalion of the Royal Australian Regiment was killed when a grenade exploded as he was asleep in his tent at Nui Dat, South Vietnam, following a night of heavy drinking within the Battalion. Private Peter Denzil Allen was convicted of Convery's murder and served ten years and eight months of a life sentence in Risdon Prison.[22]
  • December 25, 1970: Private Paul Raymond (Ramon) Ferriday took his SLR rifle and opened fire into the Sergeant's Mess of the Royal Australian Army Service Corps at Nui Dat, South Vietnam, following an all-day drinking session: Sergeants Allan Brian Moss and Wallace James Galvin were shot dead and Sergeant Frederick Edwin Bowtell wounded. During his court-martial, an Army psychiatrist described Ferriday as having a "paranoid character" and being prone to fits of rage, despite witnesses describing him as being aware of his actions and giving details of previous threatening altercations. [23] Ferriday was convicted on two counts of manslaughter and one of assault with a weapon, and served eight years of a ten-year sentence.[24]

Middle East peacekeeping[edit]

  • October 27, 1982: Irish Army Private Michael McAleavey, serving at Tebnine with the United Nations Interim Force in Lebanon, dropped into a combat stance at a checkpoint before opening fire with his FN FAL battle rifle: Corporal Gregory Morrow, Private Thomas Murphy and Private Peter Burke were shot dead. McAleavey told Army investigators they had been killed by Lebanese gunmen, but ultimately confessed, saying he had "snapped" due to dehydration and heat exhaustion. McAleavey was convicted of the murders at a court-martial and was sentenced to life imprisonment, being paroled in 2010.[25]

The Troubles[edit]

  • May 9, 1992: During the reconstruction of a security base devastated just two days before by a Provisional IRA tractor bomb at Fivemiletown, in County Tyrone,[26][27][28] while soldiers from the First Battalion Staffordshire Regiment were providing a security detail to the workers, an eighteen-year-old private fired his SA80 rifle 14 times at the company's sergeant major in a frenzy, killing him in front of the rest of the platoon. The serviceman was eventually acquitted of the charge of murder in 1993,[29][30] but declared guilty of manslaughter.[31] There were allegations of previous hazing and bullying by the non-commissioned officer against his subordinate.[31]

War in Afghanistan[edit]

  • August 17, 2002: Following an altercation, Corporal John Gregory shot and killed British Army Sergeant Robert Busuttil of the Royal Logistic Corps as he lay in a hammock during a barbecue at Kabul International Airport. Corporal Gregory, who was drunk and under the influence of medication, then killed himself. Wiltshire coroner David Masters asked the British Army "to tighten its rules on alcohol and gun security."[32]

Iraq War (U.S. forces)[edit]

  • March 23, 2003: In Kuwait, Sergeant Hasan Karim Akbar cut power to his base and threw four hand grenades into three tents where fellow members of the 101st Airborne Division were sleeping, before opening fire with his rifle as the personnel ran to take cover.

Donovan took an SA80 rifle and opened fire on CPOs David McCoy and Chris Brown after they confronted him. Donovan then forced his way into the control room, where he shot dead Lieutenant Commander Ian Molyneux and wounded Lt Cdr Christopher Hodge before being tackled to the ground by a visiting dignitary, city council leader Royston Smith, as he reloaded. Donovan pleaded guilty to Molyneux's murder and the attempted murders of Hodge, Brown, and McCoy, and was sentenced to life imprisonment with a minimum of 25 years.[37][38]

Ukrainian National Guard[edit]

  • January 27, 2022: A Ukrainian conscript soldier serving in Ukraine’s National Guard opened fire in a machine factory killing five soldiers and wounding five others before fleeing the scene and was later arrested by police.[39]

2022 Russian invasion of Ukraine[edit]

  • Unknown: According to a Facebook post by a Ukrainian journalist published on March 23, after suffering heavy losses (in excess of close to half of their brigade) a group of Russian conscripts of the 37th Motor Rifle Brigade reportedly attacked their commanding officer, Colonel Yuri Medvedev, running him over with a tank, crushing both his legs approximately 30 miles from Kyiv, during the battle of Makariv. An unnamed senior Western official said Medvedev later died of his injuries. The date of the incident is unknown but reports of the hospitalization of Medvedev appeared on March 11.[40][41]
