I was never in Vietnam; Pneumonia in basic kept me out with a "B" physical profile. I DID spend from 1967-1968 (18 months) in Korea with Hq, Hq Btry 38th Arty Bde (AD) permanently stationed on Osan AFB (south of Suwon) and was there when the N Koreans sent 20 infiltrators down to KILL the South Korean President that got spotted by a S. Korean wood cutter who reported them to the Korean National Police; The LAST one was killed on the outskirts of Seoul. I was also there when that idiot Navy Captain surrendered the USNS Pueblo without a fight compromising every confidential code in Korea ( I was in Commo). They locked down everything, no leaves, no return to the states, etc and C-141's arriving every half hour. Out the gate to check commo from the Hawk Battalion at Suwon to BDE HQ, E-7 driving, E-8 in the back seat and me (An E-4) in the right front with an M-14 and two 20 round magazines; Had to lock one in the weapon BEFORE the AP's at the gate would let us out. Yeah, I spent early July to early Dec, TDY at "Sea Range" the Missile practice range camp down on the Yellow sea ($1.00/day TDY money !!) watching Hawk Missiles and Nike-Hercules getting launched. Met and knew some who had served in Vietnam that were then assigned to Korea.
Never trust cnn, abc, cbs, nbc, msnbc for the tales they tell.
