I'm not terribly good with the rules on matrix/rigging/hacking/vehicles really, so I'm not quite sure how this works.
If you have a suit of Heavy Milspec Armor, and you equip it with two Articulated Weapon Arms, how exactly do you control them? Can you replace the default Targetting/Pilot Autosofts? Would you be able to add Fuzzy Logic to the arms and have them do their attacks against enemies with a +2 DP? Is it possible anywhere to get an autosoft at higher than R4, or is that really as high as it goes?
EDIT: How would this work out with a Cybertorso with Bulk Modification to grab three AWAs, and then Heavy Milspec to grab two more, and then dual wielding HMGs as a troll? Yes, I am aware of how utterly unstealthy, obvious, and likely to get me murdered it would be. Would it be possible though?
