SD:Brummbär

 is a German Support unit. It combined the Panzer IV chassis with a well armoured superstructure and a powerful StuH 43/1 L/12 gun capable of blasting infantry and fortifications. With a very respectable 14 frontal armour and a devastating HE gun, the Brummbär serves as the primary late-game sturdy support tank in 21. Panzer.

Strategy
As phase B rolls in, the weakly armoured Panzer IV C will soon become obsolete in the face of powerful Allied AT. The Brummbär is a powerful support tank that will have no problem filling in this spot. It is the most well armoured 21. Panzer unit save for the infamous Königstiger and it can take hits from most Allied tanks and anti-tank guns with relative impunity. Indeed, the Brummbär can take the lead in an armoured push with Panzer IV's at the back, soaking up hits from anti-tank guns and returning fire. Only the 17-pdr and its mounted variants really pose a threat against the front of this monstrosity.

Its gun fires incredibly potent 25 HE shells at 1000m range and can take out most infantry groups with one or two shots (depending on their cover). Its closest rival, the AVRE, fires even more powerful 30 HE shells but sacrifices 400m range, some rate of fire and 1 accuracy for this. Of course, HE power will do little good against enemy armour and the Brummbär should be supported by tank & anti-tank units to deal with them.

Its frontal armour, while impressive, comes at a cost. The biggest disadvantage of the Brummbär is that it is turretless and therefore needs to rotate its body in order to fire. This risks exposing its weak sides to anti-tank fire. The player must be careful not to overextend his forces and allow the enemy to flank the Brummbär.
