According to TM p. 136, small support vehicles cannot mount heavy weapons. Does this apply to the items listed under Special Equipment on the Inner Sphere Heavy Weapons and Equipment Table (p. 342)? I'm specifically interested in TAG, Guardian ECM, C3S, and Beagle Active Probes, but this section also includes A/B Pods, Narc, and iNarc systems. Most of the rest of the things under Special Equipment obviously can't be mounted, either because they are either too heavy for a small vehicle or apply to heavy weapons.
