“WZ-” is the abbreviation of initials of Chinese Pinyin of «Weapon Equipment» (武wǔ 器 qì装 zhuāng备 bèi), and it is factory designation, not the Army designation. Not all the test prototypes could receive the “WZ-” designation, but only those passed the trials and considered acceptable for mass production.
