Kalran: Tales of the four nations/Volunteer center

Volunteers, citizens of Ouroboros who chose to fight and defend their government, are uber-infantry, which have the combined features of tanks and infantry. Volunteers are uncrushable, and in fact some of the heavier ones can crush infantry. They are resistant to anti-infantry weapons but takes a bit more damage to anti-tank weapons. They can garrison structures as well. But Volunteers requires mandate to purchase, meaning its going to be harder to create squads.
