During World War II, the British Army formed a total of 43 infantry divisions. At the start of the war, the division's staff numbered approximately 13,800 officers and soldiers, while in 1944 this number increased to approximately 18,300 people. This significant change in the number of employees resulted primarily from the increase in various types of support units, and not the increase in the number of infantrymen themselves. In 1944, the British infantry division consisted of three infantry brigades, each with its own headquarters, a staff platoon, 3 infantry battalions, and engineering divisions. It is worth adding that a single infantry battalion had approx. 780 officers and soldiers and had numerous support units (e.g. 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 AA), a battalion of machine guns and mortars, as well as reconnaissance, communication and sapper units. An important element increasing the mobility of the British infantry division was its full motorization. The British infantryman's primary rifle was the Lee Enfield No.1 or No.4 rifle. As machine weapons, among others, Sten submachine guns, Bren manual machine guns and Vickers machine guns were used. The most commonly used anti-tank weapons were the 40 and 57 mm 2- and 6-pounder cannons, and later also the 76-mm 17-pounder cannons. In turn, the main armament of the field artillery was a very successful howitzer Ordnance QF 25-pounder.
Already after the first experiences of fighting in North Africa at the turn of 1942-1943, the US Army changed the position of the American armored division. From 1943, the full-time armored division consisted of three armored battalions, three mechanized infantry battalions, three artillery battalions and many support units. The exception was the 2nd and 3rd Panzer Divisions, which retained the structure with two armored regiments, three armored battalions each. For this reason, they were often called heavy armored divisions. The armored battalion of other divisions than the 2nd and 3rd consisted of three armored companies - three of medium tanks (M4 Sherman) and one of light tanks (M3 / M5 Stuart). In turn, the mechanized infantry battalion consisted of three infantry companies, a service company and a staff sub-unit. The American armored division also had, like the infantry division, a very strong artillery component, consisting of self-propelled artillery - most often M7 Priest howitzers, of which there were 54 full-time units in the division. In total, the American armored division consisted of, among others: approx. 11,000 men, approx. 250 tanks and approx. 500 M2 / M3 armored personnel carriers.
