American Self Propelled Artillery


The M-37 was based on the chassis of the M-24 light tank and mounted a 105mm howitzer.  It had better armor protection and more ammunition storage than the M-7 it was intended to replace.  Few of the 316 vehicles built were completed before the war.


    Only 100 M-12s were built  in 1942 for use in World War II.  A French First World War era 155mm gun was placed on a modified Grant chassis.  Typically the US Army Ground Forces did not see the need for a 155mm self-propelled gun at the time, so the M-12 was not put into large scale production.  When they did see combat in Normandy, they were invaluable not only for indirect fire, but also for destroying pillboxes and heavy German tanks with direct fire.
