Brummbar + Sturmtiger - What You Can Expect

The Brummbar and Sturmtiger are probably the most wanted tanks in the game, closely competing with the Sherman Firefly. 

Brummbar

The Brummbar can be found in the main list of leaked supertest icons, but no official models exist in the game. Supertest leaks  show the Brummar as tier 5 artillery, and as a premium. While shown as a premium, this tank is most likely going to be part of a German assault gun line that will be shown in 2014. This tank would play as a hybrid between an artillery and a tank destroyer. It would have a short range gun and slow reload, but monster damage for a tier 5.

Wikipedia: The Sturmpanzer was a development of the Panzer IV tank designed to provide direct infantry fire support, especially in urban areas. The result was the Sturmpanzer, which used a Panzer IV chassis with the upper hull and turret replaced by a new casemate-style armored superstructure housing a new gun, the 15 centimetres (5.9 in) Sturmhaubitze (StuH) 43 L/12 developed by Skoda. It fired the same shells as the 15 cm sIG 33 heavy infantry gun. Thirty-eight rounds, with separate propellant cartridges, could be carried. It used the Sfl.Zf. 1a sight. The combined weight of the shell and cartridge (38 kilograms (84 lb) for an HE shell and 8 kilograms (18 lb) for a propellant cartridge) made the work of the loader arduous, especially if the gun was elevated to a high angle. 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.

Sturmtiger

The placement of this tank is on that has been speculated many times over along with the Brummbar, is it a TD or an Artillery piece? While its design and fixed super-structure say TD, its nasty rocket gun is one that would put the T92 to shame. If anything WG would classify it as an "Assualt Gun" which would get different MM than say a TD or artillery piece. Expect this thing to play like a KV-2, minus the turret that is.

Wikipedia: Sturmtiger (German: "Assault Tiger") is the common name of a World War II German assault gun built on the Tiger I chassis and armed with a large rocket launcher. 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.
