Adding armor. How does that work? 1 scrap adds 3-5 durability on a new "skin" with no limit?
The Armour plates are treated as new 'parts' that have their own health, and protect whatever it is they're covering. These would be pretty important to keep small arms fire from plinking away at the parts of the actual vehicle. You did have armour plates on the APC before this little incident, but they're all gone now - Either destroyed or left behind for a little extra speed for the getaway.
Does armor affect the speed?
Yes, the individual armour plates do of course have weight, so with too many it would start to effect the speed.
How bad is it to drive on the damaged treads?
As long as you get them fixed relatively soon, it shouldn't become that much of a problem.
Are there any concern about damage to treads on paved roads?
Much less of a concern than it is for driving on dirt roads and such.
Is it a soft top or fully enclosed metal?
Soft, hence the very low health and resistance.
Are the cab and passanger compartment accessable to each other from the interior?
Yes.
The 6/1 Gatling gun...
How is it fired? On a bipod? Tripod? Do I have the tripod if it has that? Can it be fired from the hip? What is the recommended crew for optimal deployment time with the weapon?
Tripod, the tripod is included with the weapon 'item' - It can't really be fired from the hip and it's designed for use by a single person 'crew'.
The AIM Warrior
I assume the Warrior requires a tripod if I want to use it off the vehicle?
Can I link belts together/make them with links and rounds or is it going to be a ammo magazine treatment of belts?
It does not
require a tripod/bipod, but without it the recoil would add up very quickly - So it'd be ineffective unless you were quite strong. However, a tripod/bipod is not included with the weapon 'item'.
For now, the belts are just treated as magazines.
The AIM Paladin...
Can a gunsmith feasably repair it with the right equipment or should it better be labled "scrap rocket launcher parts"?
A very, very good Gunsmith - potentially. So it's pretty much scrap parts for repairing any future rocket launcher you get a hold of.
And a question for you: What sort of place would your 'Headquarters' be located in/at?
