自行化的潮流美国和德国是最先重视将马拉火炮改为自行火炮的国家。火炮射击后转移阵地,重新展开是非常辛苦的事,因此就有人提出了生产“移动更容易的炮兵车辆”。不过那种依靠铁路运行的铁道炮意义不大。野战火炮必须要有能通过恶劣地形的能力。到底是谁最先将大炮安放到坦克车上的,已经很难确定了。 The trend of self-discipline The United States and Germany are the first countries that have focused on changing the Mara artillery to self-propelled artillery. Artillery firing after the transfer of position, to re-start is very hard, so some people proposed the production of “mobile easier artillery vehicles.” However, the kind of railway guns that rely on the railway is of little significance. Field artillery must have the ability to pass the terrible terrain. In the end who first put the cannon on the tank car, it has been difficult to determine.
