And only USF armour can heal itself. You can't have everything. Think to yourself and your factionally biased self "would a Panther that can self heal be great for balance?" and then when you inevitably answer no re-evaluate why you think it would be OK with a Jackson behind it and double bar rifles in front of it.
usf pays for self repair by having shit durability on its tanks. why do you think people love the dozer 75mm so much?
