Synopsis by Hal Erickson
It is up to Charles (David Ogden Stiers), Hawkeye (Alan Alda) and B.J. (Mike Farrell) to do determine who among the 4077th's enlisted men is due a promotion. As everyone in camp jockeys for approval from the three-headed promotion board, Colonel Potter (Harry Morgan) is profoundly affected by the plight of a wounded soldier. Without saying any more, this is the episode in which a certain corporal becomes a certain sergeant.
