自战争进入机械化时代以来,无数军事家都设想能用某种方式让作为陆军火力支柱的压制火炮能够跟上机械化部队进军的步伐,紧跟进攻的前锋随时提供急需的火力支援。在这种设想的指引下,自行火炮应运而生。早在一战时,就有将野战炮架设在早期坦克底盘上作为伴随火炮的尝试,不过当时的“自行火炮”和今天还有一定的区别。前者仅仅解决了“走得动”的问题,射击时还是要像普通火炮一样放下来。真正意义上的自行火炮是以二战时期“黄蜂”、“牧师”的出现为标志 Since the war began in the mechanized era, countless military strategists have envisioned ways in which a compressed artillery piece, the backbone of the Army’s firepower, can keep pace with the progress made by the mechanized forces, and the closely-knighted forwards are ready to provide much-needed firepower support at any time. Under the guidance of this idea, self-propelled artillery came into being. As early as World War I, there were field gun carriers on early tank chassis as an attempt to accompany artillery, but there were still some differences between today’s “artillery” and today. The former only solved the problem of “walking too”, shooting it down like ordinary artillery. Real self-propelled artillery is marked by the advent of the “Hornets”, “Pastor” during World War II
