I intend to join the Corps as a bod (or as a LCpl?) sometime next year. I'm curious about the potential speed at which my career may progress. I've heard that promotion to LCpl happens rather fast. What about therafter (potentially)? People seem to think IntCorps are rather career-competitive, is that because promo's are rare, or do people simply think that because the speed at which IntCorps soldiers (being generally clever kind of people) accelerate up the ladder? Is Sgt IntCorpsAverage older or younger than Sgt ArmyAverage?
