When Cronauer first goes to see the Vietnamese village with Tuan, he is wearing a white shirt, but a plaid shirt in the close up when they enter the village.
In the bathroom, Cronauer misbuttons his shirt, but in the next shot it is fine.
When Hauk utters, "Who gave anyone permission to program modern music?", the clock above him reads "6:01"; Cronauer's initial rant goes on another three-and-a-half minutes, and when Hauk is shown again saying, "That is *not* what we program here!", the clock above him still reads "6:01".
Records disappear from the turntables in shots immediately following ones where Adrian has cued a record for airplay.
When the disc jockey announces that the next song will be Ray Conniff's version of "The Way You Look Tonight" the song actually played is Ray Conniff's version of "Smoke Gets In Your Eyes."
Jeeps used in the Vietnam war did not have ignition keys.
Armed Forces Radio provided music discs to its affiliates, including AFVN, on its own label 12" LP records. No commercial discs are permitted in AFRS facilities, and no 45 rpm records were ever played on an Armed Forces radio station.

When asking about which live acts they can get in 1965 Bob Hope is mentioned but they say he turned it down because the event was too small. But Bob Hope had already played Vietnam in Christmas 1964, and would do so every year until 1972.
Sgt. Maj. Dickerson's Class B uniform features the blue shoulder cord worn by infantry soldiers and officers. However, per Army regulation AR 670-1, cords such as this one are to be worn on the right shoulder; Dickerson is wearing his on the left, which is incorrect.
When Marty is reading the news on air while filling in for Adrian, he references "All-Star Rookie Pete Rose." Although Pete Rose's rookie season was 1963, two years prior to the movie's setting, the use of "All-Star" could be referring to his 1964 Topps All-Star Rookie card or his first selection as an All-Star in 1965. An All-Star "Rookie".
When Cronauer is visiting Trinh's place, a female villager speaks Thai instead of Vietnamese.
The movie was filmed in Bangkok, Thailand, where the traffic is set on the left. In a scene of traffic in a crossing, cars are seen entering a two-lane street in clearly the wrong lane, as you see directing arrows on the tarmac facing the other way.
Right before the restaurant explosion, you see a couple enter through the front door, but if you keep looking, you can clearly see both running right before the door closes.
Cronauer closes his final show (in 1965) with Louis Armstrong's "What a Wonderful World," which wasn't recorded until 1967. (Director 'Barry Levinson' was aware of this but the song was perfect for the montage scene he used it on, he decided to ignore this anachronism.)
When Adrian has the three shrimp heads on his fingers pretending to be the Supremes, he refers to the group as "Diana Ross & the Supremes." The film takes place in 1965. The group would not be known as Diana Ross & the Supremes until July of 1967.
Early on in the movie, Adrian Cronauer pretends to play a record backwards, mimicking it saying, "Freddie is the devil...Freddie is the devil". The film takes place in 1965, and backward messages on records were a generally unknown phenomenon until the Beatles famously made use of this technique a year later with the release of their single Rain, which features the first backwards lyric; "When the rain comes, they run and hide their heads." Furthermore, backward "devil" messages on records did not become an issue until a few more years down the road in the 1970s.
The film universally shows US soldiers carrying M-16s, but as this film takes place in 1965 and M-16s only began to be issued in March of that year, the majority of units were still equipped with the very different-looking M-14. Indeed, the 1st Infantry Division, the unit Cronaur performs for while stuck in traffic, were not issued the M-16 until 1966, yet the film shows them equipped with it in 1965.
In the opening scene when Garlic is driving Cronauer through the city, they pass through a major intersection. A 1971 Holden motor car is clearly visible 6 years prior to its release.

Though the film is supposed to be set in Vietnam, in an opening shot of a main road, the Thai Parliament Houses are clearly visible on the horizon.
Lt. Haul complains that the men never salute him. They are indoors and military personnel do not salute indoors.
Throughout the film, armed forces personnel are shown wearing garrison caps and other headgear (referred to as "covers") and saluting indoors. This is not correct, as uniformed personnel are required to remove covers when indoors (therefore "under cover") and do not salute indoors.
After "What a Wonderful World" plays, Cronauer calls the singer "Louie B. Armstrong." Louis Armstrong's middle name was Daniel.
During the initial meeting between Adrian and Lt Hauk, when Dickerson walks in and asks for Adrian's paperwork, Lt Hauk replies calling him 'Sergeant'. Dickerson's rank is Sergeant Major and someone as status/rank conscious as Lt Hauk would be sure to use the full correct rank.
Garlick quotes Cronauser as having referred to Pat Boone as a beautiful genius, however the term he used was misunderstood genius.
