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 infantry division. From 1943 onwards, each infantry division had three full-time infantry regiments, in turn composed of three infantry battalions. In addition, the infantry regiment also included other units, for example: an anti-tank company, an artillery company or a staff company. In total, the US Army's infantry regiment numbered approximately 3,100 soldiers. It should also be remembered that the division also included a strong artillery component consisting of four artillery battalions - 3 light and 1 medium, most often armed with 105 and 155 mm howitzers. There was also, among others, an engineering battalion, a repair company, a reconnaissance unit and a Military Police platoon. In total, the US Infantry Division numbered approximately 14,200 people from 1943. It quite clearly dominated the artillery over the German division and had much better and - above all - fully motorized means of transport, which made it a highly mobile tactical formation. It also had much richer "individual" anti-tank weapons in the form of a large number of bazooka launchers, of which there were over 500 in the entire division.
British Commandos is a British special unit that gave its name to the Polish word for commandos. The unit was formed by the order of the British Prime Minister Winston Churchill in 1940, after the defeat and the withdrawal of the British Expeditionary Forces from France in the same year. By definition, the unit was to operate in German-occupied Europe and conduct broadly understood subversive, sabotage and intelligence activities. Initially, soldiers from the British Army were recruited to Commandos. It is assumed that in the period 1940-1945, about 25,000 people passed through the ranks of this unit, including not only the British, but also volunteers from countries such as Greece, France, Poland and the USA. In commando units, a lot of emphasis was placed on the initiative of a single soldier, the ability to act independently and to cope with extremely difficult combat conditions. The training was very difficult, demanding and in the course of World War II - it kept changing, over time, including, among others, recalling artillery or air support. One of the most famous actions performed by Commandos was the 1942 raid on Saint-Naziere, but the commando units also operated on a large scale during the Normandy operation in 1944.
