Were 4th army 4th Division who were airlifted to Seoul Korea in April '71? I was an MP Ist Lt with the 518th!? I've only found one who was with us, but he passed away last year. Someone sent me a message that there was perhaps one or two guys that post here that may 1) Have been an MP the the 518th, and 2) another that went to Korea for injuries in Apr of 1971. Thanks!!!
