Since you asked for feedback, silversurfer, here's my two cente:

First of all: I like your changes and they do make sense, so no problem there generally.

I feel weapon's condition degrades too fast. I don't like playing with militias, so what I usually do is leave a single merc in every sector I need to keep (mostly towns and sectors with a lot of loot), but him in sone room without a window and ambush all the attackers when they come through the door. Gamey, I know, but I don't see an alternative, since I simply don't like militias. Long story short: I was defending Tixa with Shank and he went through two rifles (Mini-14 and M4, I think), each starting out with 85+ condition. With the Mini-14 he couldn't even get through half a mag before it jammed so badly he had to drop it. I know it's a desert sector, but he never left the armory next to the bathrooms...

Also, some questions regarding the new repair system: Does this mean that you need MEC to clean guns now? Gun-cleaning skills drilled into recruits are a far cry from actual engineering skills, so I would really object to a situation where low-MEC soldiers take hours cleaning there guns.

What do you consider the "default" setting in your new system? If set to only allow Perko and Arnie to actually repair weapons, doesn't that completely invalidate all the engineers?

Biggest problem: Guns jamming can very quickly lead to the gun being ruined (dropping to 1%) - does this affect the dirt status only or does this reduce the threshold to 1% as well? The latter would be terrible, because this would mean a rifle in pristine condition could very well be utterly destroyed in single Tixa defence.
