Katabatic is an arctic map. The main flag bases are huge. Having a vehicle station, top mounted turret, and a forward turret for defenses. There are multiple inventory stations inside as well as the generators. So try to keep enemies from getting inside. As there is plenty of room to hide inside this massive base. The side bases hold inventory stations as well as the pulse sensor atop. These are in the middle of the map. So occasionally you can make a quick run with the flag and stop there to refill. Watch out for enemy vehicle traffic and keep at least one heavy defending the flag along with medium armor support.
