I don't plan much for using Halo Arsenal instead i plan to use Red Faction Arsenals like Grinder with explosives, Arc Wielder that the electricity can kills the operator inside any vehicle, Proximity Mines, Thermobatic Rocket include Nano Rifle, etc.
Hmm... i still want to bring some walkers and some arsenals like gauss rifle, perhaps some rail driver as well as i get some references from the games i play in.
For my faction effect is as long as my faction was entrusted in some productions the production rate can be increased, naturally they are often used as a messenger or combat because of high mobility and well-trained. If not entrusted then the production increase effect will not be applied.
