These photos are were purportedly taken by a Chinese Private Military Contractor of other Chinese PMCs protecting Chinese interests in Burma. Chinese businesses own a lot of farm land and many quarries on the Burmese side of the border which are used to fuel the Western Chinese economy.
The guns are interesting and not the usual rusted Soviet-era AKs or Type-56 rifles you would expect. This PMC is armed with a Beretta 92 (or a clone), a Norinco CQ (M4-style AR-14) and a Ruger P89 (or a clone).
Many thanks to Xiao for the photos.Related
