We should be able to repaint any captured vehicles, so there's no chance of mixing them up. It's already difficult enough to distinguish our own units and theirs on sight.
It's a bit scary how much my brain's been occupied with coming up with strategies for that assault on the airbase that I've been talking about. Especially when it's likely that two minutes into the assault the usual thing happens: three of us end up bleeding out on the ground, while Dema manages to hole up in a nearby hut, waiting for us to respawn and come back with reinforcements.
