One of the most overlooked part of the game is outfitting soldiers when it comes to SP/Co-op or Dedicated Servers - this is a context sensitive huge pain in the ass. You guys should've had something built into the editor long before Zeus came along in order to really make co-op mission making greatly accessible to everyone.
I'm kind of in awe of the fact that it's not in there and that it takes days and even weeks to get enough time to learn enough scripting to deal with such a fundamental issue for anyone not just wanting to make SP-only maps.
