Not knowing the exact stats but it hardly seems like a joke in comparison. The AVRE does not have to stand still for a minute to reload. That's worth a lot since you don't have to go way back to ensure safe surroundings while reloading.
Stnading for a minute is worth everything if you always penetrate, one shot medium tanks and shoot from fog of war without reaviling yourself to enemy
I'd say give it cooldown. With constant sight it is a bit broken.
But give it cooldown like "scanning for 20secs" and then you need to wait XX secs to use it again.
Oh yeah glorious OKW infantry design. Where a horde of basic (vet 5) long-ranged infantry is what you are facing with A move (+ Shrecks on volks). Jägers are no long range support, they are basically yet another infantry squad which happen to have a nice crit chance.
I did not say Jaegers, but like Jaegers/Pathfinders.
Fragile unit, with good sight, with % chance to snipe when model has X% of HP, but rather useless in real fight.
