Forgotten Heroes.

An independent movie from 1990 highlighting the valor of the men who served in Vietnam. Ramon, an American soldier, is newly added to a platoon of Marines ordered into Cambodia to extract a Russian general named Zelenkov. As Ramon arrives in the camp, the audience gets to know each member of the team, and Ramon suffers from the normal hazing of a new team member. The soldiers successfully land in Cambodia and extract the general, but an elite troop of Russian paratroopers tracks them down. Several battles follow, with many redemptive acts of sacrifice.
