SD2:3-cal Moździerz

 is a Poland Artillery unit in Steel Division II.

Background
The Ordnance ML 3 inch mortar was the successor of the Stokes mortar in British service, designed to provide infantry units with close artillery support. Inexpensive and easy to produce, the mortar had somewhat limited firepower and range in 1939, but revisions to the propellant, sights, and general design quickly brought it to parity with German designs. They were so effective, in fact, that it remained in service for three decades, finally superseded by the L16 81mm mortar in 1965.

In the 10th Polish Dragoons Regiment's Motorized Companies there are Mortar Detachments with two mortars each. While the Infantry Battalion of 3rd Polish Infantry Brigade has a Mortar Platoon in the Support Company.
