Building LOS

[Doug Leslie]

Is there LOS between a unit on the ground level of P8 and level one of O9? I would have thought not but the VASL LOS tool disagrees.

It's perhaps unfair to say the LOS tool disagrees. It's probably better to say that it has not been coded for that situation.

 

[Bill Kohler]

I say no. I explored this issue previously, and concluded that what matters is where the LOS crosses the hexside, if it's within the building depiction or not. (See the last sentence of B23.25.)
I sent a Q&A to MMP about it a couple of months back but haven't gotten a reply.


My conclusions:
Open LOS between different floors:










Blocked LOS:









Borderline Case:






This question is also pertinent to Factory TEM and Factory MF/MP.

Rule #1: The LOS tool is not the rule. Consider it a cheat sheet that is interpreting the rules.

Paper and eASLRB LOS rules have it blocked.

If there is not LOS between P9 and O8, then the ground level units are not ADJACENT. Broken unit in P9, KEU rolls up on O9. If there is not LOS, then the broken unit is not DM.

The rule is A6.2.

LOS extends into or out of obstacles, but not through them into hexes beyond the obstacle except in
certain cases wherein the target/firer are at an elevation ≥ the height of the obstacle or are adjacent to
a hexside obstacle.

P9 and O8 are clearly in obstacles. There is a piece of O8 that requires LOS to leave and reenter the building and then enter P9. The LOS extends out of the obstacle.

Consider board 18a. Does the separate structure in P6 block LOS from P6 to Q7? How about P8 to Q10? It is interesting to see a statement that the rule says "x" without any effort to use the rule and apply it.
