In the anime girls army: they would definitely steal any firearms that they like. They are mostly gun aficionados and would immediately recognize the type 56 as the exception that proves the rule. A commie gun that is actually really good and reliable.
IRL: the US special forces train with commie AKs as well as US guns because they know they'll be forced to switch to captured Kalashnikovs if the shit hits the fan and they run outta ammo for their m4 variants. The AKM is the best you'll find if things get real in a 3rd world country.
