Honestly haven't bothered using it in the latest iteration.
But isn't the design flawed to begin with? You get a guy with an StG (close to mid range) yet want to keep the Kar98k Grens at range. Wasn't really that cool on Volks to begin with... and those get more StGs.
Yeah its terrible. Another thing destroyed by the classic double nerf. Don't understand why they go through the effort to destroy something into the ground just to end up buffing it again later on.
The original upgrade if im not mistaken gave an extra man, a recieved accuracy buff, and more damage which is obvious that it was going to be too strong.
The 5th model plus maybe a slight reduction in reinforcement cost would have been enough.
