No problem. Are you sure you’re playing RF correctly? Units get to fire in an opponents turn if they haven’t moved in their previous turn, like an ambush, so holding off pays off.
Good question, and I don’t know. This was back in the nineties and I just remember my Republicans disintegrating in the face of Nationalist firepower. Part of that was certainly the fact that my guys had to assault the Nationalist positions in the couple of games we played, but it just seemed to encourage static battles.
