re: #222 Decatur Deb
Not in the old days. My short-tempered uncle made corporal several times.
My grandpa (Pacific Theater, WWII, ACOE, landing boat guy) never made it past captain because he had a CO who had it in for him. He was pretty bitter about it. Then we refused to give veterans benefits to the Filipinos, even those that had served and died under the command of US officers, and he became really disenchanted with the military.
