Luftwaffe Flak Badge The badge was awarded to servicemen of the Flak artillery who distinguished themselves in action against enemy aerial or ground attacks. Prior to the introduction of the Ground Assault Badge of the Luftwaffe, this badge could be awarded to a serviceman for the participation in three separate combat operations against tanks, bunkers, or ships. Processing and shipping within the continental U.S $30 plus a 1.5% insurance fee. The badge has a silver wash which is very even and frosty on the reverse but heavily darkened on the front.
