Sturmtiger

The Sturmtiger is a German SPG/TD.

A assault gun which can play as both a tank destroyer and a self propelled gun. It can fire its 5+ ton shells over cover, has heavy firepower, and has a fixed casemate. It can switch from SPG mode, which enables it to fire over cover, to TD mode, which largely reduces the targeting range in turn for increased firepower, and vice versa.

Abilities and Strengths
The Sturmtiger has fantastic frontal armour for a TD. The shells are very powerful, able to punch through thick armor. Moreover, it also plays as an SPG, enabling it to hit foes protecting themselves behind cover. Plus, the gun is decently accurate, unlike the Conqueror Gun Carriage.

Weaknesses
Since it also plays as a TD, it has a fixed casemate, which means it has to turn around to defend itself from flankers and scouts. And since it's also an SPG, its ammo is limited, only 14 rounds per Sturmtiger.

Tactical Strategies
User:

The Sturmtiger's decent armor doesn't mean in should be placed in the line of fire. Instead, it's better to place it at the second line of fire, where it can switch to SPG mode and fire at enemies while being covered by other larger and heavier tanks. Or, if your enemy is using weak to medium strength clusters, it's advised to switch to TD mode at fire at the clusters with increased damage and place it at the frontlines. And make sure it doesn't get flanked by enemy flankers or scouts.

Enemy:

As with all casemate tanks, try flanking them from the sides and the rear
