Chinese People's Liberation Army uniform circa 1965-1980s. Mao wanted a true guerrilla army, so he simplified the uniforms, going as far as abolishing military ranks and their insignia. These cause problems when they fought the Vietnamese; while the Vietnamese are like the Chinese, also adapted to the so-called "people's war", the Vietnamese kept rank insignias; the Chinese didn't, and these hindered command effort. So rank insignias are put back about 1988; that uniform have been also been phased out.
