Regiments operations There's also the matter of supply. Regiments follow the Wargame model, in that supply is quantum stem cells that can be used to repair tanks, heal/resurrect/respawn fallen men, and resupply ammo. However, it's a global resource that can and will run out, especially if you get a Grad. You'll still get a small trickle of supply by camping your own spawn point, but it's not nearly enough. Therefore, you have a good reason to spent precious points on something so easily expendable.
