Built on the same lines as the British Stokes mortar, the 4.2in Mortar was originally designed for laying smoke, when WW2 broke out the U.S. Army developed an HE round which turned the 4.2in into a very useful heavy support weapon. It was issued to independent heavy mortar battalions and issued at divisional level.
