Another award, the Expert Infantryman Badge is similar in appearance - it only lacks the laurel wreath - is earned by infantrymen who demonstrate exceptional infantry skills by participating in rigorous testing.
My duty as a platoon leader of a base camp reaction force did not qualify me for the award (in case you were wondering).
These requirements were spelled out in Army regulations that I wore like armor when confronted by superior officers demanding that I ignore them. One major slammed his hat on the ground and shouted at me to issue orders awarding the CIB to every member of his non-combat unit. He cited another infantry division that was handing out CIB awards to everyone. Incidentally, the commanding general of that division was subsequently ordered by the theater commanding general to rescind every order and reissue them only to qualified recipients.
