Need to point out for anyone who actually think this story, the Myanmar sections is base on real life event.
While there are conflict in the Chinese and Myanmar border. Most of the fighting is done between the Wa Socialist state soldier and Myanmar army's, and even if Chinese para-military forces joins the fight, which they don't, the Wa state got that cover pretty good, the Chinese would be using Norinco M4 or anything beside AK47 variants, even the Wa soldier don't use AK47, they uses the much better Type 81 rifle.
Myanmar army also don't use AK47 variants, if they got their hands on any, it is for training and deposable left over. They use Galil 5.56mm rifles and machine gun.
