Coming Home is a 1978 drama directed by Hal Ashby (The Last Detail) that chronicles the experiences of two Marines, one an experienced military officer and another whose wounds left him paralyzed, upon their return to the States following their service in the Vietnam War. The film would garner Academy Awards for both Jon Voight and Jane Fonda for their roles in the film.
The following weapons were used in the film Coming Home:
The movie begins a couple days before Captain Bob Hyde (Bruce Dern) ships out to South Vietnam. At one point he is seen qualifying with his M16 Rifle. His M16 features a three-prong flash hider and 'slickside' upper receiver (lacking the forward assist), but features the 'full' magazine fencing of the M16A1. This indicates it is either simply a 'frankengun' built with a combo of the aforementioned parts, or could possibly be a later variant of the Colt Model 604, which was the M16 variant adopted by the Air Force. Other Marines are seen qualifying with M16s, though most of the rest of these seem to be M16/SP1s. Neither the Model 604 nor the original M16 were ever adopted by the USMC.
Type 56 Carbine (Chinese SKS)
A year later, Bob (Bruce Dern) returns from South Vietnam and learns about his wife Sally (Jane Fonda) and Luke Martin (Jon Voight). He retrieves a disassembled SKS rifle from his footlocker (which is full of souvenirs from Vietnam) and reassembles it minus the wood furniture. Later Luke Martin (Jon Voight) breaks the rifle down. It appears to specifically be a Type 56 Carbine, the Chinese variant of the SKS - This is a nice (and accurate) detail since the Chinese supplied weapons to the North Vietnamese Army as well as the Viet Cong.
