The game's 49 unlockable honors are broken down into five groups, Campaign (23), Firefight (7), Multiplayer (4), Training (6) and Player Experience (9). You can find the descriptions of six of the Achievements posted after the jump. For all the rest, you're just going to have to use your imagination. For instance, that one with the Caduceus on it? We're pretty sure that's the Achievement for when you put down your guns, go back to school, and become a Registered Nurse.
