General Ruthven is a higher-up in the Army and is the person Billy and Sergeant Dime are forced to speak to when they refuse Norm Oglesby's offer of funding for the Bravo Squad film. Fortunately for Billy and Bravo Squad, General Ruthven is a Steelers fan (and therefore hates the Cowboys by default), so he doesn't force Bravo to accept Norm's deal.
