When Lance Corporal Drummer is wearing his service alphas, he is missing a bronze service star on his Afghanistan Campaign Medal ribbon. All campaign medals are worn with at least one bronze star on them.
LCpl Drummer is wearing an Afghanistan Campaign Medal, but he is missing the NATO Medal that is also awarded with the campaign medal.
