M12自行火炮是美国陆军于1942年投产的履带式自行火炮，主要用于装甲部队的火力支援。该型号基于M3/M4中型坦克底盘，搭载法制1918M1式155毫米加农炮，采用无防护开放式战斗室设计，弹药基数为10发，需配合M30弹药运输车进行作战
。其研发始于1941年，采用一战末期封存的法国GPF火炮技术改进方案，共生产约100辆，其中74辆经改装后投入欧洲战场。该火炮因固定射击模式限制，实战中常需近距离直接炮击目标，在诺曼底登陆及亚琛战役中承担突袭火力任务。1945年后被M1A1加农炮取代，但作为美军首型量产自行火炮，为后续M40等型号提供了技术验证基础。

Because when I first published this post, I didn't notice that the M12 self-propelled artillery had to be matched with the M30 ammunition transport vehicle.three
So my next post may be sc2 water reconnaissance plane，
It could also be M30 ammunition transport vehicle.
