Thanks to the Soviets and Chinese certain parts of their military were in the

Or maybe the transportation
that managed to ship arms and materiel to sustain the combat
operations in the south.

Ed, that transportation network consisted of a hundred or so WW II era French
trucks and a few hundred bicycles. Hardly "hi-tech".

Damn! I had no idea that the hundreds of NVN trucks
we destroyed in Laos during 1970/71 had left them with
so few vehicles at home, just a year or so later.
