This variant gives me a bit more speed and durability with the increase in standard engine size. I am thinking about backing the engine down to the standard 300 for another ton of SRM ammo but I have had good luck with this. It has a bit of range with the AC5's and the SRM4's with the Mlas are good in close quarters. Weapon Groups 1. MLas 2. AC5 3. SRM4+A 4. Alpha
