"On paper an SS-Panzergrenadier division was organised and equipped in much the same manner as an equivalent Heer (Army) division, which consisted of two Panzergrenadier regiments supported by a Panzer battalion, an artillery regiment, a tank-hunter battalion, an assault gun battalion, an anti-aircraft battalion, a reconnaissance battalion, and a pioneer battalion. The biggest difference was the amount of armour available. Whereas the Heer division has just one battalion, SS-Panzergrenadier divisions had an entire regiment and eventually, for a while, including a company of heavy Tiger tanks. Additionally, unlike the motorised army Panzergrenadier divisions, the Waffen-SS Panzergrenadier division included a full battalion mounted in armoured half-tracks. The only Heer division that was comparable to the organisation of an SS division was the elite Grossdeutschland division."
