Sure. That'S my mission
Batallion-level battles were possible with SB without problem, I even set up something that was close to a clash between two-on-two brigades, but it was quickly over.
If the new SB Pro is able to manage something of that size remains to be seen. A year ago a beta tester or so wroite in their forum that frames were stable despite him setting up "multiple batallion" sized battles.
