This is a light mortar introduced for British service during the 1930's. It is a simple design consisting of a tube and baseplate. The firer aims by tilting the barrel and lining up the sights, this is not as accurate as designs with a bipod but at the ranges the 2" was designed for this is not a problem. One advantage of this system is the ability to fire at very low angles allowing direct fire. The 2" mortar is trigger fired with a lanyard.
The standard service version of the 2-inch mortar had a barrel length of 21 inches and could fire a high explosive bomb weighing 2.25lb out to a range of 500 yards. With such a short barrel firing was by a small trigger mechanism at the breech.
The 2 inch mortar was originally issued one per infantry rifle platoon. It had the advantages of being more portable than larger mortars and gave greater range and firepower than rifle grenades.
