''Tour of Duty'' was an American drama television series on CBS. It ran for three seasons from 1987 to 1990. It obviously was inspired by the UsefulNotes/AcademyAward winning feature film, ''Film/{{Platoon}}'', making UsefulNotes/VietnamWar stories acceptable mainstream entertainment.

The show followed an American infantry platoon on a tour of duty during the Vietnam War. The story focused mainly on Bravo company's second platoon under the command of 2nd Lieutenant (later 1st Lieutenant) Myron Goldman (Stephen Caffrey), and Staff Sergeant (later Sergeant First Class) Zeke Anderson (Terence Knox).

The first season opens in 1967 and follows a standard light infantry platoon. In the second season, the troops found themselves relocated to a base near Saigon while conducting the typical "search and destroy" missions. Female characters were also introduced (in hopes of gaining more female viewership and because of the premiere of the ABC Vietnam Army Nurses drama ''Series/ChinaBeach'' which was aimed at a more female audience). In the third season, the remaining female character was killed off and the platoon was transferred to a SOG (Studies and Observation Group) unit under the command of Colonel Brewster (Carl Weathers), conducting covert operations in Vietnam and in Cambodia, culminating in the fictional version of the raid on Son Tay Prison. The third season was the show's last.

!!''Tour of Duty'' contains examples of:

* AnyoneCanDie: The series did not shy away from killing off major characters, often without warning, highlighting the arbitrary and unfair nature of combat.
* CaliforniaDoubling
** The first season was filmed in Hawaii, whose rain forests were a convincing stand-in for Southeast Asia
** The second and third seasons were filmed in California, and don't look nearly as good. Ironically, the rolling yellow hills would have been a decent stand-in for the country near the DMZ during the dry season, where they were stationed in season 1, but it utterly fails as jungle around Saigon. Near the end of the series, a new guy lampshades it by pondering why Vietnam isn't as green as he expected, and Anderson explains that it is the result of the use of Agent Orange near their bases.
* DownerEnding: Many.
** [[http://www.tourofdutyinfo.com/EpGuide/Volunteer.htm The finale of the second season]] ended with [[spoiler:a surrounded Lt. Goldman and Sgt. Anderson calling down an artillery strike on their own position. They get better]].
** Many individual episodes, such as "[[http://www.tourofdutyinfo.com/EpGuide/brothers-fathers-sons.htm Brothers, Fathers, and Sons]]" and "[[http://www.tourofdutyinfo.com/EpGuide/roadrunner.htm Roadrunner]]"
** Finally, the last episodes of the series are almost universally depressing. [[spoiler: Lt. Goldman is completely disillusioned and has stooped to the same tactics he testified against a friend for. Zeke, with nobody to return to, is given another batch of young idiots to watch die. Marcus, now the last of the old squad, is wounded in a firefight. Pop loses his son and is badly wounded. Griner comes home blind. Hockenbury's pacifism costs the life of a comrade and he is stuck in a care center watching wounded men die. Ruiz and Percell both struggle to adjust to life back home, and McKay is grounded from combat flight, has difficulty getting a job, and when he does he can find no joy in flying in a civilian capacity.]] The series saved its emotional gutpunches for last.
* DuringTheWar: During the VietnamWar to be precise.
* EnsignNewbie: 2nd Lt. Goldman is this at the start of the show. He gains experience and maturity quickly over the course of the first season.
* HaventYouSeenXBefore:
-->'''Private Alberto Ruiz:''' What's the matter? You niggers never seen a spic before?
* HonorBeforeReason: In ''Gray-Brown Odyssey'', Lt. Goldman and a female VC prisoner, whom he holds at gun point after a prior ambush that also leaves him temporarily blind, come across a wounded communist sympathizer and his starving family. After hearing the VC explaining about the plight of the said family of four, Goldman gives them all his rations and is about to move on. The VC, knowing that Goldman does not understand Vietnamese language, not only tells the family that Goldman has just offered them food but also asks the family to mob the blind Goldman and help her escaping. A girl from the family grabs a knife to free the VC...... only to be prevented from going through with it by her wounded father, who thanks Goldman for the food and allows him to leave with the VC still his prisoner.
* TheMedic: Randy "Doc" Matsuda was Bravo Company's designated medic during the first season, before becoming a victim of AnyoneCanDie.
* OfCorpseHesAlive: Some of the characters are forced to do this when one of the new guys gets drunk in town and jumps to his death. They initially plant the body in the jungles with the intention of shooting him in order to make it look like the VC killed him. The platoon sergeant however, finds out, but not before the base is attacked by the enemy. The new guy's corpse startles a VC sapper who fires at the body before being killed. The dead soldier is honored for fighting bravely in the base's defense.
* RankUp: Myron Goldman goes from 2nd lieutenant to 1st lieutenant between first and second seasons, and Staff Sergeant Anderson is promoted to Sergeant 1st Class in season 3.
* RealSongThemeTune: "Paint It Black" by The Rolling Stones.
* {{Retirony}}: The show had an odd tendency of killing off anyone who was 'getting short' (ie: Was about to complete their mandatory one-year Tour and be sent home). [[AnyoneCanDie Even the main characters weren't always immune to this]].
** Played with when one character was only grievously wounded when he found out he was 'getting short'. In a much later episode, we find out that said character later recovered in hospital, re-enlisted, got promoted, and returned to combat...only to be KilledOffForReal this time.
* SergeantRock: Staff Sergeant (later Sergeant First Class) Zeke Anderson, especially in the first few episodes when Goldman was more an EnsignNewbie. He is a grizzled veteran who has the respect of all of the men in TheSquad.
* ShownTheirWork: in the first season, particularly, the show went to great lengths to show accurate weapons, equipment, and tactics as well as creating a fictional yet believable military unit with it's own backstory.
* SleevesAreForWimps: Anderson rarely wears his uniform shirt when out in the field, preferring to wear his equipment harness over a tank top, so his well-muscles arms are on full display.
* TheSquad: The focus of the series is very much on 2nd platoon Bravo Company, complete with nicknames for almost every platoon member.
* SquirrelsInMyPants: One of the soldiers is suffering from the runs, and has to keep going off into the bushes while on patrol to drop his pants. While he does so, a large toad jumps onto his dropped pants. At the same time, he happens to see some Vietcong slipping out of a tunnel to evade the American soldiers; the soldier quickly yanks up his pants and HilarityEnsues.
* TokyoRose: The series briefly featured a Vietnamese equivalent, with one GI asking another why he listened to that stuff. He replied that the propaganda was annoying, but that the ''music'' they played was actually pretty good.
* TrainingThePeacefulVillagers: "[[http://www.tourofdutyinfo.com/EpGuide/ParadiseLost.htm Paradise Lost]]
* VietnamWar: The show follows an American infantry platoon on a tour of duty during the Vietnam War, starting in 1967.
* WarIsHell: Like most series about the VietnamWar made after ''Film/{{Platoon}}'', ''Tour of Duty'' focuses a lot on the horror of combat.
