United States Army Basic Combat Training covers a wide range of combat survival elements on top of the conditioning a soldier needs for battle. Among these are a series of courses for close combat. They included training in the bayonet, and a short set of classes on a form of grappling known as Brazilian Jujitsu. Mind you, I emphasize 'short' here, because six hours a day for two days learning the basic principles of grappling does not a master grappler make.
