The Type 75 155 mm self-propelled howitzer (75式自走155mm榴弾砲 nana-go-shiki-jisou-115mm-ryuudan-hou) is an older 1st generation armored artillery vehicle. It holds a crew of five.
They were first seen in combat after the hunt for the Flame Dragon on Mount Tube by Itami's group. Not long after the Dragon was killed by C4 and her offsprings, Mowto and Towato, were chasing Itami, the vehicles opened fire upon them, dealing massive damage as well as knocking them to the ground.
During the Imperial Civil War, they were used to destroy the ambushes of the Royal Army, designated by helicopter or reconnaissance groups.
