Some pointers here:
1: Where does all this "Conscipts are Crap" stuff come from?
The conscripts of Napoleonic France, Prussia, Russia and Imperial Germany beg to respectfully disagree, and I apologise in advance to other notable concript militaries I no doubt ommited.
2: Having operated the G36, yes, I like it, it is accurate, kind towards your shoulder and is very well suited to impressing the female population.
However, its training with the gun, not as much the gun itself, that makes the difference.
3: Regarding the PLA beeing underestimated, that is propably true, although I think that the Russian army gets understimated more in general, with the armies of France beeing underestimated more often by the US (who, incidently, never had large scale conflicts with La grande nation). One could even make a point that the US troops (at least in the last century) may be the most commonly overestimated military formation.
