I have quickly check :
- Open the equipment file of the sub-mod (not vanilla game or main MC mod);
- Find E8, you can read "0,1,2,4,5,6" inside;
- replace all the values by just one "21".
I have not tested, but it should work.
I strongly advise you to keep a copy of the equipment file unmodified somewhere, so that you can put it back again in its place if it don't work.
Edit: There is one last thing to do. Open each map on the scenario editor.
In edit ---> Scenario Params ---> Nations : put Ukraine as "Axis".
Make sure that each scenario have Ukraine in Axis side, and you should be good
I'm not sure that the campaign is balanced like that: you can modify the starting date of the ukrainian units in the "equipement" file to be sure your vehicles have a chance against what the ennemy send at you
I think that Akkula and Rimski created their equipment file to have balanced campaigns, but Ukraine was certainly not thought to have its own. it could be wise to experiment a bit with starting date.
Edit if someone want to made the same change in the future and find this post.
I was talking about the campaign file in this post, not the equipment one. I was certainly tired...
You also have to unload the mod from JGSME, modify its files, then reload it to apply your changes.
