How about rangers and airborne that laugh at MG42's while sprinting right past em? Just saying... Well, yeah, that picture says it all.
You're right... but FireUp! is totally different compared to a lol cloak in front of an HMG.
The cloak give you the ability to lure away if you made a mistake, FireUp! gives you a temporary boost, but you get punished when the
Airbornes/Rangers will go into the exhaustion.
Allthough the Sturmtruppen have more HP then the Airbornes or Ranger will normally take significant loses with the first bursts, while I have seen
Sturmtruppen doing some weird shit without loses.
