The Siege of Firebase Gloria is not a very well known Vietnam war film. In fact it hardly gets a mention at all and is overshadowed by films such as Apocalypse Now, Platoon, Full Metal Jacket and others.

The premise is as follows: a Marine patrol led by sergeant Hafner (the great R. Lee Ermey) ends up in a remote US Army outpost deep in the jungles of Vietnam right at the start of the Tet offensive. Hafner takes command and must fend off waves of attacks by the Vietcong and NVA.

The story is quite interesting of how these men, outnumbered and almost forsaken must defend themselves against all odds. Although Ermey's role isn't too big (the film focuses on a few key soldiers), he is great in every frame he is in. Having been an actual Marine, he reprises his role as a tough commander with a witty tongue. The film in general find a nice balance between the main story while at the same time showing how war takes its toll on men. Interestingly enough the North Vietnamese commanders are also portrayed and fortunately not as cartoonish enemies but competent leaders.

The production values are quite good, there are lots of real helicopters, the sets and location are grand and well built and the action scenes quite vast in their scale.

However the film doesn't reach the levels achieved by Apocalypse Now or Full Metal Jacket. Despite that, its still worth a watch.
