BTW - for the german raiders, how about including an upgrade/technology to simulate disguises (like the one for "Orion" above)? It could be equipped just like how you equip better weapons & radar for subs. Once enabled it could suppress the detection abilities of enemy units' sensors, simulating them being fooled by your neutral paint scheme. I know this is already possible for U-Boats with the rubber coating that impedes sonar - maybe you could dig around in the files and create a corresponding trick to impede visual sensors...
