I need advice, I can't handle it in the late game 30+ min, I mainly playing Soviets. DPS from multiple Su-85 isn't enough cause they use loss blockers or retreat at any threat. Mines also doesn't work cause I can't put it in neutral ground and players never overextend their Sturm. The problem is constant resource bleed and I can't bleed my opponent more effectively.
This following guide will help you destroy any and all axis heavy armor (that fucks up) in the game, relatively easily. The sturmtiger has a lot of health, AT guns or some tank destroyers might do damage, but it is all in vain if it lives.
What to do? bum rush the tank
Short explanation: The skilltiger is a behemoth with loads of health, you will have to do more than park an AT gun or two and hope for the best, he can take the DPS and safely retreat. You gotta stun the sturmtiger and rush him with your team's armor
Okay, how do you do this? Two ways:
With UKF ally: Get your ally to make at least one or two firefly tanks, upgrade them with the Tulip rockets. in the meanwhile, get your own tank destroyers, i assume SU-85s, and perhaps even a T-34 along, and wait. Once you inevitably see a sturmtiger pulling up to fire at your own lines, you collapse with your whole might upon him. Firefly tanks will chain stun the ST, the rockets themselves do great damage, and your tanks will collapse easily upon the tank. It is a lot of force and hopefully it should die. Additionally add AT overwatch for good measure.
Without UKF: The procedure is basically the same, except you will compensate with T-34 rams instead. This is a bit unreliable due to many factors that can come in, but you can follow up on the ram with guard button, AT overwatch, and tanks driving behind the sturmtiger. Generally you simply want to stun the ST and even damage it's engine, so it cant escape death, a t-34 or two are acceptable casualties
