I propose distance factor into fights more than it does already. For example, if you're attacked by someone with a gun in an outdoor room, you could have to spend a combat round rushing to close the distance to start hitting them. And perhaps there could be a 'disengage' verb or the like, only available in neutral (?)/defensive/guarded posture, with accompanying dodge check to create this distance at the cost of a combat round, along with people out of melee 'range' having significant bonus to their chance to escape a fight if their attacker does not 'rush' to close the distance.
