hit-and-go pack
n.— «As soon as he lands, he has the option of going right to his survival kit and unzipping what’s called a hit-and-go package that has some of the most important items in his survival kit, and immediately start his evasion procedures, especially if there’s hostile forces in the area. Q: What’s in the hit-and-go pack? A: Hit-and-go probably is water, an additional radio, extra batteries, first aid kit, and that’s about all the room there is. It’s a small, cylindrical type of plastic or canvas package that he would take with him.» —“DoD News Briefing” by Terry Murray et. al U.S. Department of Defense June 8, 1995.
