The 21 cm Mörser 10 (21 cm Mrs 10) was a heavy howitzer used by Germany in World War I. It replaced the obsolete 21 cm Mörser 99 which lacked a recoil system. For transport it broke down into two loads. Some howitzers were fitted with a gun shield during the war. As it was also intended for siege use a concrete-penetrating shell was also used.
