German Anti Tank Gun, Artillery and Anti-Aircraft Guns Documentary

Hummel (German: "bumblebee") was a self-propelled gun based on the Geschützwagen III/IV chassis and armed with a 15 cm howitzer. It was used by the German Wehrmacht during the Second World War from early 1943 until the end of the war.
The full name was Panzerfeldhaubitze 18M auf Geschützwagen III/IV (Sf) Hummel, Sd.Kfz. 165. On February 27, 1944, Hitler ordered the name Hummel to be dropped as it was deemed inappropriate for a fighting vehicle.
Nashorn (German "rhinoceros", pronounced [ˈnaːshɔɐ̯n]), initially known as Hornisse (German "hornet"), was a German tank destroyer of World War II. It was developed as an interim solution in 1942 by equipping a light turretless chassis with the Pak 43 heavy anti-tank gun. Though only lightly armoured and displaying a high profile, it could frontally penetrate any Allied tank at long range, and its relatively low cost and superior mobility to heavier vehicles ensured it remained in production until the war's end.
The Sturmpanzer (also known as Sturmpanzer 43 or Sd.Kfz. 166) was a German armoured infantry support gun based on the Panzer IV chassis used in the Second World War. It was used at the Battles of Kursk, Anzio, Normandy, and was deployed in the Warsaw Uprising. It was known by the nickname Brummbär (German: "Grouch")by Allied intelligence, a name which was not used by the Germans. Just over 300 vehicles were built and they were assigned to four independent battalions.
The German Panzerwerfer is one of two different types of half-tracked multiple rocket launchers employed by Nazi Germany during the Second World War. The two self-propelled artillery vehicles are the 15 cm Panzerwerfer 42 auf Selbstfahrlafette Sd.Kfz.4/1 (based on the Opel Maultier, or "mule", half-track) and 15 cm Panzerwerfer 42 auf Schwerer Wehrmachtsschlepper (or Panzerwerfer auf SWS).
Sturmtiger (German: "Assault Tiger") was a World War II German assault gun built on the Tiger I chassis and armed with a 380mm rocket-propelled round. The official German designation was Sturmmörserwagen 606/4 mit 38 cm RW 61. Its primary task was to provide heavy fire support for infantry units fighting in urban areas. The few vehicles produced fought in the Warsaw Uprising, the Battle of the Bulge and the Battle of the Reichswald. The fighting vehicle is also known under a large number of informal names, among which the Sturmtiger became the most popular.
