From mid-1942, the 2-pdr was increasingly displaced to infantry anti-tank platoons, to Home Guard units in Great Britain, and to the Far East, where it was still effective against the smaller and more lightly armoured Japanese tanks.
Its performance as an anti-armour weapon was improved later in the war with the development of more sophisticated ammunition and got an additional boost with the introduction of the Littlejohn adaptor, which converted it to a squeeze-bore design firing specially-designed shells at much higher velocities.
