I like the idea of Salvaging, but there are some big questions that go along with it. First, would you be salvaging individual pieces, i.e. engine, wheel, axel, gears, seat, windo, armor plating, turret, sensors, , radar, etc. Now this could be really cool, because it could potentially lead to the creation of a custom vehicle of pretty much your own design. Everbody loves a little moped with tank armor on it. These wouldn't necessarily be uber vehicles, just vehicles with more weapon or armor (which would decrease speed), better engines, axels, wheels or treads (increasing speed), and the like. However, the problem is when scavenging, do things miracously appear in your inventory, or do the weigh you down, or must you pull them along or do you just load them up on a sled or something, which zooms you and your scrap metal back to your base?
The second possibility would be to scavenge a generic, all-purpose material, i.e. "scrap" or "parts" or "gears", which you would pick up from anything, you'd get more from a tank than a gun for example. These things could then be crafted into whatever you want and would not have to be lugged around, but easily carried and stored. However, you loose the uniqueness of items and creating your own things, unless you created various parts from these pieces, then put them together to form your custom vehicle. Personally, the first way seems a lot more interesting and fun.
Either way, it would require some type of workshop, which is where a guild would come in handy, to create these items. Maybe you would only need a workbench to create armor and weapons (think KotoR and KotoR II) and a garage to make the big things, which would also be helpful in repairing vehicles. You could also throw in the need for certain tools/lifts to be able to create these things and pu them together. Now you could sell these costum items to other people possibly or hand them out to your guildmates. Also a vehicle could be customed designed or tweaked for a mission or while on the battlefield. Can't get troops past their line of defense? Create a small quick APC or just take off the weapons from one of the APCs on the field to quicken it up. Enemy tanks hasseling your troops? Paste some armor and massive turrets onto your vehicles and blast them away. Sure these is a little far-fetched, but it would be extremely fun and really add to the game.
