Small nitpick. You mean conscripted not enlisted.

I have no experience in the matter but I suspect that's not it. A conscript and a recently recruited professional soldier should in theory have the same level of training. Many professional soldiers only enlist for a few years.

I reckon it's more that equipment is a lot more complicated now than in the past. And maybe something to do with literacy levels in the 1960s meaning you couldn't trust a soldier to have read and understood a manual.
