I'm liking the idea of a Panzerjager squad, but the MP-40s are bad and I think its safe to say nobody really wants to see LMG blobs replacing Shrek blobs.
Personally, I think they should be a little like the PE with a variety of upgrades. Give them stick-nade back, remove flame-nade and give them either a 2x AT Rifle package, a 3-4x G43 package and a Flamethrower package, all mutually exclusive.
Recently I'm working on a mod to play with my friends. Three of the changes are the next:
-Volksgrenadiers now have grenadier panzerfaust ability (copy paste)
-Volksgrenadiers can choose one (and only one) from the following upgrades:2x G43 for 60 muni (requirement: 1. halftruck set), 3x MP40 (con ppsh stats) for 40 muni (requirement: 2. halftruck set), 1x Mg34 for 60 muni (requirement: 3. halftruck set)
-tankbuster squad (2.truck): 320manpower, 4man, 3xMP40 (inferior stats to volk MP40 package) 1xShrek.
The thing is, I really don't know how this would work in the game, so hard testing will be done.
