I can provide a page number when I get home, I don't have access to TW from work. Yesterday I played my first game with Hidden Units as per the Breakthrough scenario in TW. When my unit revealed itself with a surprise attack, we ruled that "a weapon attack" means ONE weapon. We figured that using all weapons would be grossly OP and devalue Ambush roles a lot, since most of those units have at least one big damage weapon. Did we rule that correctly?
