So now that we acknowledged they are PAP in the 2nd and 3rd pics...
Boy are they quite well armed for border guard duty/internal affairs...I mean, HMG, LMGs, AKs...and I'm not surprised that they are using this old stuff...afterall the PAP receives hand downs from equipment no longer used by the PLA, but that is good enough...they seem better equipped than any army unit that ever existed in the ranks of the KMT and CCP during the Sino-Japanese War, and if these fellas are fighting in their home lands and had a few tricks taught to them by SOF officers for guerilla or underground purposes, these guys have the definite advantage of having more guns than the Vietcong.
While sure we can talk about what PLA doesnt have, and that their new boots are quite bad etc...I mean, compared to the 1930s-40s...
KMT and CCP troops didn't even have adequate food, let alone shoes to wear (they had to make shoes out of straw for some of them), not every man had a rifle, they wore backpacks of most primative types, no helmets, only probably enough ammo for two or three clips for their bolt actions, few machine guns...this was a problem too during the Korean War...
At least now, look at the PLA. Shoes, well fed (i mean, sitting in a barracks dining is a luxury compared to serving under any Chinese army until the latter half the 20th Century), probably at least minimal yet enough pay to encourage boys to enlist, they have HMGs even down to the level of PAP, and their mobility has been increased without heavy clumsy backpacks, and at least they have shoes...I guess the boots just need taking time to improve and get used to, as these boys probably have worn their rubber sneakers too long.
As for 5 rounds a year? WHAT THE? Oh please! If that was true, even I'd expect the average Taliban man to go through several clips just for firing his gun towards the sky when he celebrates. I mean, I guess whoever said that is AN IDIOT, NOT IN THE ARMY, and if that guy is correct, then I guess someone just misread a story of a soldier fighting in the Sino Japanese War and thought it was bout a PLA soldier TODAY (afterall, bolt action rifles only took 5 rounds, and back then KMT/CCP ammo was really really scarce).
