I can't seem to get the ranged changed for the le_ig and I'm pretty sure it has to do with the fact that it has a UI range (represented by a yellow circle).
The Leig has 4 different hardpoints (weapons) in ebps/combat_ext. 1 for autoattack and 3 for abilities. You need to edit them all, and also the 5 abilities in ebps/ability_ext.
I added a panzerfaust attack to obersoldaten but I'm not sure I want to keep it. For one there is no animation so it looks silly. The ability also was only working when you click the ability on the right side of the screen; the hotkey didn't work and I'm sure it is because I didn't click something somewhere.
The hotkey probably doesn't work because andother ability or upgrade uses the same one.
The animation must be added to the model:
"..\\..\\..\\german\\weapons\\panzerfaust_100\\panzerfaust_100",

The only outstanding errors I need to fix are the Elefant call in still being displayed and the OKW command panzer being available for the Ostheer.
The elefant call-in is located in army/abilities.
I saw a notice in the files about okw base unpacking and I will give that a go when I get back to modding. Being able to move the trucks around is another cool feature I plan to steal from your mod.
This feature requires a few steps which a not present in the existing files. I will try to keep it short:
Create a wreck with health_ext/rebuild_squad: the sws truck.
Create an ability which spawns that wreck (spawn_entity), kills the structure and finally adds 1000 hp to the wreck. The wreck will spawn a new truck in the exact same direct as you structure. (The spawn_squad action has a random rotation).
The animation which I use has 9 delayed actions, one every 1 sec, which sets te build variable from 0.9 to eventually 0.1. The whole ability takes 10 sec.
