Combat Medic: Most medics are just as capable in combat as their regular squadmates.
Even in the US campaign it is told that the GRM tanks and technicals are useful addition to your forces and that you should try and capture them by forcing the crew to bail out and have your engineers restore them to working order. The first GRM mission tells you to order your poorly armed militia to pick up UAF weapons.
Enemy Exchange Program: Very strongly encouraged in the game.
Civil Warcraft: The final GRM mission is a civil war within the GRM. Break Out the Museum Piece: Somehow, Lee-Enfield bolt action rifles were common for the insurgent arsenal, before they upgrade to the infamous AK rifles. The UAF has no qualms regarding executing innocent unarmed civilians ( according to the GRM view, anyway).
Black-and-Gray Morality: The GRM vs UAF conflict. Authority Equals Asskicking: The UAF General in the GRM campaign will pick up a rocket launcher and try to fight you. Arbitrary Gun Power: With the exception of Hardcore mode, direct hit, even point-blank and to the head, isn't enough to kill an enemy soldier, possibly to prevent the direct control mode abuse.
