As in any war, it depends upon which period you are talking about. The PAVN was quite well "provisioned" particularly when compared to their NLF counterparts. The PAVN was very well provisioned after about 1970. The NLF slight better, particularly the units which had had their ranks filled with PAVN soldiers. After 1972, both groups were much better off, yet again.
Again, it depends upon which period you're talking about and whether your talking about local force, main force or regular force units. Until about 1968, NLF units tended to be fairly poorly equipped and trained but after '68, it all starts to change and improve. After the defeat in the Tet'68 Offensive, most NLF units were decimated and had their ranks filled with PAVN soldiers who were generally better trained, better equipped and better commanded than NLF forces generally had been.
At the bottom rung, of course there was the local force units, made up of volunteers who still had a day job, while their night job was supporting the Revolution. They were generally, poorly equipped and trained. Main Force units had given up their day jobs generally and fled into the jungle but were still largely volunteers in the South. Equipment and training was spotty at best, with some good to excellent units and many poor ones as well. Regular force units had generally been given at least some training and some good equipment, with their ranks often filled out with members of the PAVN who had come down the Trail from the North.
