I just finished a protracted fight on a planet; my forces won, but were completely supply-deprived by the end.
In preparation for the next fight, I transported them all home, and then added Supply units to every formation. If I read the rules correctly, this means they should be "consumed" to bring the supply of the unit back up to 100% (or at least above the 0% it is sitting at, in case I haven't added enough. I can always build more).
Instead, the formations are staying at 0%, and the supply units are just chilling with them. I guess they are playing poker or something.
Am I misunderstanding how to resupply?
I know I can have Supply units "In the field" with the troops, and if I do, the combat troops supply% won't go down per round, as the LOG units get used up instead. But once a unit gets dropped out of supply, how do I get them to visit the local depot to pick up some spare bullets before lifting off again?
