I wouldnt have any worries about us trouncing the chinese if they got involved anyway. Yes theyve got the man power buuuuut everything i buy these days seems to made in china. The build quality of most it is horrendous.
Imagine it now.... A couple of chinese soldiers running toward you.
1 belts out 'DIE' in mandarin and takes aim... Ttttttt, chamber's jammed!
2nd has a bash. Tears off the ring pin of his grenade with hos teeth, goes to chuck it at you n all the contents fall out!
It'd be a joke
In a seriousness though... We're to far away to be hot by anything the koreans fire n by the looks of of reports knocking about the chinese are getting a bit p*ssed off wi em.
