An ammunition unit (1) designed to he adaptable to different types of targets (2,2') or situations. The said ammunition unit comprises cylindrical warhead charges (4, 5) that confine or form explosive compositions (23), on or around the outside of which there are effect layers or casing containing effect elements (25, 27). These effect elements together with the explosive compositions (24) constitute the combatant function. Two or more cylindrical warhead charges (4, 5) are arranged essentially parallel alongside each other or inside each other. Each of the cylindrical warhead charges comprises effect layers around their cylindrical outer surface that provide different effects in target. The cylindrical warhead charges are rotatably arranged to assume different rotational setting modes, and in each such mode the same type or co-ordinated types of effect layers are directed outwards.
