Known as either "Trinity" or "America's Battalion", the unit falls under the command of the 3rd Marine Regiment of the 3rd Marine Division.  The unit consists of approximately 1124 U.S. Marines and United States Navy sailors.  Like most battalions of the U.S. Marine Corps, 3rd Battalion, 3rd Marines is made up of three rifle companies (India, Kilo, and Lima), a Headquarters and Services (H&S) company, and a weapons company.  The battalion was originally formed at Marine Corps Base Camp Lejeune, North Carolina in 1942 and saw action on both Bougainville and Guam during World War II, where it was awarded the first of its Presidential Unit Citations for "gallantry, determination, and esprit de corps in accomplishing its mission under extremely difficult and hazardous conditions"; and the first of its Navy Unit Commendations for "outstanding service".  Marines in the battalion were also awarded one Medal of Honor and seven Navy Crosses during the war.  Following World War II, 3rd Battalion was disbanded until 1951, when it was reformed in California.  The battalion was alerted for possible deployment during the 1956 Suez War and the 1958 intervention in Lebanon.  In 1965, the Marines of 3rd Battalion were deployed to the Vietnam War and participated in Operation Starlite, the first major Marine engagement of that conflict.  The battalion continued to see major action through Vietnam and was rotated back to the United States in 1969.  Famous alumni from its time in Vietnam include Corporal Robert Emmett O'Malley, the first Marine in Vietnam to be awarded the Medal of Honor, Oliver North, and John Ripley.  Around the end of the Vietnam War, the Battalion was deactivated for a second time in 1974. Tropic Thunder is a 2008 satirical action comedy film directed by Ben Stiller.

Team America: World Police is a 2004 American-German satirical action comedy film starring puppets produced by Scott Rudin, Matt Stone, and Trey Parker, written by Parker, Stone and Pam Brady and directed by Parker, all of whom are also known for the popular animated television series "South Park".  The film stars Parker, Stone, Kristen Miller, Masasa Moyo, Daran Norris, Phil Hendrie, Maurice LaMarche, Chelsea Marguerite, Jeremy Shada, and Fred Tatasciore, and is a satire of big-budget action films and their associated clichés and stereotypes, with particular humorous emphasis on the global implications of the politics of the United States.  The title is derived from domestic and international political criticisms that the foreign policy of the United States frequently and unilaterally tries to "police the world".  Featuring a cast of supermarionettes, "Team America" depicts a paramilitary police known as "Team America: World Police", who attempt to save the world from a terrorist plot led by Kim Jong-il. The Vietnam War POW/MIA issue concerns the fate of United States servicemen who were reported as missing in action (MIA) during the Vietnam War and associated theaters of operation in Southeast Asia.  The term has also referenced issues related to the treatment of affected family members by the governments involved in these conflicts.  Following the Paris Peace Accords of 1973, 591 American prisoners of war (POWs) were returned during Operation Homecoming.  The U.S. listed about 2,500 Americans as prisoners of war or missing in action but only 1,200 Americans were reported killed in action and body not recovered.  Many of these were Airmen who were shot down over North Vietnam or Laos.  Investigations of these incidents have involved determining whether the men involved survived their shoot down; if they did not survive, then they considered efforts to recover their remains.  POW/MIA activists played a role in pushing the U.S. government to improve its efforts in resolving the fates of the missing.  Progress in doing so was slow until the mid-1980s, when relations between the U.S. and Vietnam began to improve and more cooperative efforts were undertaken.  Normalization of U.S. relations with Vietnam in the mid-1990s was a culmination of this process.
