What about if you had two different multi-story building adjacent and the enemies are on the same floor. That wound be considered adjacent, correct? I always thought the +2 was for concentrated fire, hand grenades, and whatever other close quarters weapons (Trench guns, grease guns, etc...) are available. I would think that the +2 would stand as the range is the same for grenade, shotguns, etc... In fact maybe it should be + 3 for adjacency from attack from a higher level building to an enemy on the ground. After all, the men in the building will have windows and kill holes to use and protect, grenades would be easier to throw and aim, and knowing the entrances should carry that over if OP fire is taking place. Say the enemy is coming up the stairs. Staying with that the men on the ground should get a +1 for their adjacency bonus. It's harder to trow grenades upwards and you'd be spotting "smaller" targets. This is the only thing that kills me with Lock N Load rules. Why can't we have the "why". Why is it that way, what is the designers thinking behind the rules. We always say Lock N Load has a historic component based on realism. So rules explanations should be easy. I was under the impression Bunkers, Multi-Story Buildings, and there are a few other such cases concerning in-hex terrain which I can't remember now were considered two distinct, separate hexes in one.
