Under Fire is a 1983 film directed by Roger Spottiswoode and starring (Nick Nolte), (Joanna Cassidy) and (Gene Hackman) as journalists covering the Nicaraguan Revolution.
The Chadian rebels that Russell Price (Nick Nolte) accompanies in the introduction of the film are armed with Finnish Valmet M76 rifles, standing in for the Kalashnikov rifles that were difficult to acquire during the early 1980s.
One of the rebels in the introduction is armed with what appears to be either a genuine AK-47 or Norinco Type 56 rifle, though it is too blurry for accurate verification.
Oates (Ed Harris), an American mercenary whom Price encounters throughout the film, carries a Uzi submachine gun which he carries during the scenes set in Chad. Later, a Nicaraguan rebel leader (Lucina Rojas) also carries a Uzi with a fixed stock.
Oates carries a derivative of the M1911A1 pistol in a shoulder holster. Rebels who hijack a plane to drop propaganda leaflets that proclaim that the rebel leader Rafael is still alive also are armed with a M1911A1.
One of the most common weapons in the film is the FN FAL rifle, which is used by Nicaraguan Guardia Nacional soldiers and FSLN rebels. Oates also carries a FN FAL with a telescopic sight in Nicaragua, using it during a shootout with rebels in a church. A FN FAL is used by a soldier to summarily execute Alex Grazier (Gene Hackman), in a moment deliberately modelled after the real life death of ABC reporter Bill Stewart, who was also killed while covering the fighting.
The FN FAL 50.63 Paratrooper rifle, distinguishable by its shorter 18 barrel and folding stock, is also seen in the hands of Chadian rebels and Nicaraguan soldiers.
