Cobra Gold is an Asia-Pacific military exercise held in Thailand every year. It is the largest Asia-Pacific military exercise held each year, and is among the largest multinational military exercises in which the United States participates.
About Cobra Gold
Cobra Gold was first held in 1982. It served as military training exercise to improve coordination between the armed forces of the United States and Thailand in both hostile military and humanitarian efforts. It also had the goal of strengthening ties between the U.S. and Thailand, the oldest ally of the United States in the South Asia region. More recently, Cobra Gold has served a humanitarian mission, as military personnel deliver health care to the local Thai population, and as a testing ground for new battlefield technologies such as solar powered weaponry.
As of 2014, Cobra Gold has three distinct activities. The first is the combined arms live fire exercise (CALFEX), in which live ammunition is aimed at predetermined targets. Troops then assault a beach and landing zone while this live fire occurs. The second activity is a command post exercise (CPX), in which military officers engage in computerized war games, disaster relief, or humanitarian missions over several days. The final activity is assisting the local Thai population.:226-228
Cobra Gold has expanded to include 35 nations as of 2016, including Indonesia, Japan, Malaysia, Singapore, South Korea, and other South Asian and Pacific Ocean countries. China was admitted to Cobra Gold exercises for the first time in 2015 as well, although Chinese military forces were only allowed to participate in humanitarian assistance training.

Recent Cobra Gold exercises
Participants in Cobra Gold 2013 included the United States, Indonesia, Japan, Malaysia, Singapore, South Korea, and Thailand. Twenty other nations participated in observer status. For the first time, Burma joined the exercise (as an observer). Exercises held during Cobra Gold 2013 included an amphibious landing involving ground assault fighter jets, attack helicopters, and landing craft; mock military raids involving small boats and helicopters; a practice evacuation involving civilian populations; a combined arms exercise held while live fire occurred overhead and nearby; and training in biological, chemical, jungle, nuclear, and radiological warfare.
Admiral Samuel J. Locklear III, commander of the United States Pacific Command, described Cobra Gold as "the Pacific's signature exercise" in 2014, and noted that it was among the largest multinational military exercise in which U.S. armed forces participate.
The United States reduced its participation in Cobra Gold 2015 to signal its disapproval of the military coup which occurred in Thailand in 2014. The U.S. sent 3,600 troops to the exercise in 2015, down from 4,300 in 2014. The U.S. also cancelled the exercise in which troops practiced under live fire during an amphibious landing. However, American military forces did participate in a civilian evacuation training exercise, and the operation of U.S. troops in formation in the field in cooperation with the military forces of other nations. Nevertheless, more than 13,000 military personnel from six nations actively participated in Cobra Gold 2015, while other nations participated as observers.
The United States postponed its participation in a March 2015 meeting with Thailand to begin planning for Cobra Gold 2016. American military officials indicated they might cancel the exercise outright as a protest against continuing military rule in Thailand.
