Sir Digby Chicken Caesar's X2 XP Mod
This mod cuts the time it takes for a unit to get a promotion
So if it took your unit 150 kills to get their first stripe, it now takes them 75 kills to get it ... etc ...
Now tested & working fine
This is a mod so unzip & place file in data folder and add this line to your user.script:
mod "MOD_SirDCC_x2_XP_MOD.pack";
