How to Jagdtiger?

DomoSapien: It's a sniper tank. The armor is somewhat forgiving when top tier but the gun is a fast firing laser with good penetration.

Coupled with the lack of mobility and turret, it's effectively a back line support vehicle that becomes more of a mid-range support when top tier. 

The gun is very accurate and punchy, so you don't necessarily need to get to the fight quickly (because you won't)
