What Price Glory (1952)

In 1918 France, Captain Flagg commands a disreputable company of Marines; his new top sergeant is his old friendly enemy, Quirt. The two men become rivals for the favors of fair innkeeper's daughter Charmaine, but the rivalry goes into reverse when Charmaine proves to be angling for a husband. When the company is ordered to the front, this comedy interlude gives way to the grim realities of war.
