Who canceled the project for the Landkreuzer P. 1000 Ratte, which would have surpassed the Panzer VIII Maus as being the heaviest fully enclosed armoured fighting vehicle ever built?
Panzer VIII Maus Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by the advancing Soviet forces.
4th Panzergrenadier Division (Bundeswehr) The 4th Panzergrenadier Division ("4. Panzergrenadierdivision") was a West German mechanized infantry formation. It was part of the II Corps of the Bundeswehr, which also incorporated in 1979 the 1st Mountain Division and 1st Airborne Division, and the 10th Panzer Division. II Corps was part of NATO's Central Army Group (CENTAG), along with the Bundeswehr's III Corps and the American V and VII Corps. In the wake of military restructuring brought about by the end of the Cold War, the 4th Panzergrenadier Division was disbanded in 1994 with some of its forces being used to form the Airmobile Forces Command /4th Division.
