I guess this falls into the "game" side of this HOBBY. I can tell you DAK has had 3 Different Sturm Tigers over the years and they obviously are IFA and a royal pain to fight! We kid the operators that we should put 6 emitters in the barrel to simulate the "spread" and only let them fire 11 times during the whole event. The reality is to battle with it you need to spin the tank a bit and flank it a lot. Eventually it throws a track and you can kill it.

IFAs have their place but I'd really like to see more elephants..

The only real equalizer is more allied TDs come on Chaffee / Hellcat / M10!
