Panzergrenadier is a German term for a formation of panzer grenadiers, i.e. infantry units trained to fight in close cooperation with their own tanks. This term was officially used in 1942, when infantry divisions were renamed grenadier divisions and motorized infantry divisions into panzer grenadier divisions. It is worth adding that in the years 1937-1942, the Schützen Regiment was used to describe the infantry regiments serving in armored units. Theoretically, the basic equipment of armored grenadier divisions was to be armored half-tracked transporters, especially Sd.Kfz.251, but due to insufficient production, these infantry were often transported by trucks. As a standard, an armored grenadier division consisted of three infantry regiments, two battalions in each regiment and numerous support units, including anti-tank, anti-aircraft, sapper and communication units. Self-propelled guns, such as the StuG III, were often used in these formations. It is worth adding that the armored grenadier divisions were formed not only in the Wehrmacht, but also in the Waffen SS - for example the Totenkopf Division or the Hohenstaufen Division.
The Volkssturm is a German military formation of a militia or a mass movement from the end of World War II. The formation was established by a special order of Adolf Hitler in September 1944, due to the catastrophic losses of the German armed forces, especially on the Eastern Front. All capable men between the ages of 16 and 60 served in its ranks. Volkssturm members did not receive virtually any uniforms, except for special armbands, and their weapons were outdated rifles, pistols and machine guns, very often from the First World War. The only modern weapons used by the Volkssturm were the Panzerfaust and Panzerschreck anti-tank grenade launchers. Units of this formation were initially used to protect roads, railroads and fortifications, but from the beginning of 1945 they were already used on the front line - especially in the defense of Wrocław, Kołobrzeg and Berlin.
