In my humble opinion, there is no need to create an entire Div's worth of Anti-tank capability. Usually infantry bns have trained hunter-killer teams with AT capability. In Pakistan, the Anti-tank capability exists in three forms. At Infantry unit level, they have their own AT weapons (RPG-7s etc.). Then you have the LAT (Light AT) units with jeep (Defender 90) mounted BakterShikan/Green Arrow ATGWs and then HAT (Heavy AT) with ITOW (improved TOW) capability (also known as M901s) or TOWs mounted on M-113 APCs. These units are attached to various brigades/divs on an as-needed basis based on adversary's armour threat perception.
