During World War 2, 10.5cm weapons were the principal field guns at divisional level in the German Army.   The leFH 18/40 entered service in 1943 and was a marriage of the leFH18 barrel with muzzle brake to the Pak 40 carriage in an effort to produce a lighter weapon.   Late war shortages meant that the gun was produced witha variety of wheels.   By the time that the war ended, the leFH 18/40 accounted for over half of the German light field howitzers produced.
