I didn't know this movie existed until I accidentally ran across it at a retail store. Intense not so covert war action with good drama between characters and a few twists in the plot. The movie highlights the individual heroic efforts in battle, the insanity and randomness of events during conflict (and the responses by the players), and the disconnect between the battlefield and the strategic planners (both blind to each other).
Sergeant Sullivan (Lee Van Cleef) shows scares from previous conflicts, illustrating the personal side that never is far away from the professional. His past torments him throughout the film. The personal conflict and struggle between Sergeant Sullivan and Captain Valli (Jack Kelly) is constantly simmering and sometimes boiling over. Captain Valli, untested in battle, struggles to lead his newly appointed team on a very dangerous and unpredictable mission. At one point, he displays a dilemma in leadership, having to choose between his hard earned gains in the battle with his new team vs. new direction from above. The result of that decision has enormous consequences.
A very cool movie.
