“They conveniently forget how the Soviets gave satellite info to the NVA? (Among many other things.)”
Especially Russian aircraft, and Russian pilots to fly them.
22 re Soviet BLoc weapons in Nam. It was their long range artillery, better than our 155s or the few 175mm arty we used there, that made the difference in the 1975 final offensive. Also we didn’t give the VNAF enough replacement aircraft, esp. F5s and Spookies, to make a major impact.
