During World War II, the British Army formed a total of 43 Infantry Divisions. At the beginning of the war, the division's personnel numbered approximately 13,800 officers and soldiers, while in 1944 this number increased to about 18,300 individuals. This change in personnel numbers was mainly due to the increase in various types of support units and not an increase in the number of infantry units themselves.

In 1944, the British infantry division consisted of:

• Three infantry brigades, each with its own headquarters.
• One headquarters company.
• Three infantry battalions.
• Engineering units.

Notably, a single infantry battalion had approximately 780 officers and soldiers and included numerous support units, such as a mortar platoon or a reconnaissance platoon. The division also included a de facto artillery brigade with five artillery regiments, including one anti-tank and one anti-aircraft regiment, as well as a machine gun battalion.
