Some very rare and unprecedented video showing several footages depicting the Chinese para-military People's Armed Police and PLA border guard units fighting, what China calls, the "Three Evil" - Terrorism, Separatism and Religious Extremism - at their far-western frontier bordering the central asian countries and Afghanistan, where militants attempt to cross the border regularily to receive training and weapons outside of China, and to return to fight against the Chinese state.
It is understood that these footages not only show excercises but also real raids against militant hideouts, such as a certain one in 2010.
Noticable is the usage of Flamethrower weapons and grenade launchers against militants hiding in mountain caves - with terrifying effects.
One thing is clear: China isnt playing games. If anyone wants to support Terrorism, Separatism and Religious Extremism in China, he will be crushed by the full might of the Chinese armed forces.
