The series was originally set in Fort Baxter, a sleepy, unremarkable U.S. Army post in the fictional town of Roseville, Kansas, and centered on the soldiers of the Fort Baxter motor pool under Master Sergeant Ernest G. Bilko. However, Bilko and his men seemed to spend very little time actually performing their duties—Bilko in particular spent most of his time trying to wheedle money through various get-rich-quick scams and promotions, or to find ways to get others to do his work for him.
