Another problem was with the United States Army. The United States Marine Corps had enthusiastically lent bases, Marine extras, and film of its campaigns to Hollywood films to boost its public image (see The United States Marine Corps on film). But the Army was not so keen on this project. The Army felt that Ranger operations led to heavy losses of excellent soldiers that the Army thought would be better employed leading regular infantry units. By the 1950s, rather than the separate Ranger units shown in the movie, the Army preferred training individual officers and NCOs at the Ranger School, who then returned to their parent units and trained them in Ranger tactics and military values. Thus, the U.S. Army's co-operation was limited to training the actors and providing black-and-white stock footage.
