I read this on DriveThruRPG today:
The combat rules are a major breakthrough. One general combat resolution procedure covers all types of combat: hand-to-hand, melee weapons, small arms fire and fire against armored vehicles. Once the basic three-step combat sequence is understood (Did you hit? Where did you hit? How hard did you hit?), combat is quick and easy to resolve, but the wide range of weapons values keeps the system rich in detail.
I'm not familiar with Twilight 2000: how do the combat rules compare with Traveller, Snapshot, AHL, etc? Are they compatible?
