I've been capturing dozens of supply units from various White armies in my game. You would think this was a good thing, but I don't seem to be able to give them any replacements. They look like regular Red units. They all show heavily damaged, but when I look at my replacement screen the number of hits on supply units is quite low. I bought a pile of supply replacement points but my captured supply units don't seem to be taking up any replacements. I don't know how much supply they can carry but it doesn't look like they can take on a full load. I'm assuming that their carrying capacity is lower either in proportion to the amount of damage they've taken or perhaps because individual elements within the unit (there are 4 elements in a normal supply unit) have been destroyed. And can't be replaced...
Since the new patch makes it impossible to build forts or depots with damaged units (apparently?), these guys are pretty useless. Can we fix this in an upcoming patch? Either they should be regular red units or they should have some other status so you can buy replacements for them. Or there should be something you can do with them. Right now, I'm sending them around to my various fortified positions in hopes they will keep them from surrendering.
