What is grenadiers?

Answer 1

Panzer grenadiers were infantry that were attached to armored or panzer grenadier divisions. The panzer grenadier division were infantry divisions that also had native panzer units as part of the division instead of being attached from another unit. The term Panzergrenadier was applied equally to both the infantry component of Panzer Divisions as well as the new divisions known as Panzergrenadier Divisions. Most of the Heer's PzGren. divisions evolved via upgrades from ordinary infantry divisions, first to Motorized Infantry divisions and then to PzGren. divisions, retaining their numerical designation within the series for infantry divisions throughout the process. This included the 3rd, 10th, 14th, 15th, 16th, 18th, 20th, 25th, and 29th divisions. Others, such as the Großdeutschland Division, were built up over the course of the war by repeatedly augmenting the size of an elite regiment or battalion. The Waffen SS also created several PzGren. divisions by the same methods, or by creating new divisions from scratch later in the war. A number of PzGren. divisions in both the Heer and Waffen SS were upgraded to Panzer divisions as the war progressed. The Panzergrenadier divisions were organized as combined arms formations, usually with six battalions of truck-mounted infantry organized into either two or three regiments, a battalion of tanks, and an ordinary division's complement of artillery, reconnaissance units, combat engineers, anti-tank and anti-aircraft artillery, and so forth. All these support elements would also be mechanized in a PzGren. division, though most of the artillery, anti-tank, and anti-aircraft elements were equipped with weapons towed by trucks rather than the relatively rare armored and self-propelled models. In practice the PzGren. divisions were often equipped with heavy assault guns rather than tanks, due to a chronic shortage of tanks throughout the German armed forces. A few elite units, on the other hand, might have the tanks plus a battalion of heavy assault guns for their anti-tank element, and armored carriers for some of their infantry battalions as well. On paper a Panzergrenadierdivision had one tank battalion less than a Panzer division, but two more infantry battalions, and thus was almost as strong as a Panzer division, especially on the defensive. Of 226 panzergrenadier battalions in the whole of the German Army, Luftwaffe and Waffen SS in September 1943, only 26 were equipped with armoured half tracks, or just over 10 percent. The rest were equipped with trucks.
