My troops are replenished with fresh replacements and stationed back at home. However, when I view the troops in the GU menu, their supplies have not replenished, although they are at home (Earth). How do you replenish the group supply of your formations after a war? Do you have to produce group supplies or something?
I do have supply trucks, but they're also running low due to them continually resupplying the troops in the past conflict.
