Source: Military Edge
This 155 mm self-propelled howitzer is used by the Chinese, Algerian, Kuwaiti, and Saudi Arabian armies. A crew of five soldiers can fit inside these tanks: a gunner, commander, driver, and two loaders.
Weapons wise, it’s loaded. The PLZ-45 is armed with a 45-caliber main gun that is 155mm, and includes a semi-automatic loader. Secondarily, it includes a roof-mounted W-85 heavy machine gun with two sets of four-barrel smoke grenade launchers on the turret’s side.
