A rule that came up in one my games during the EEC-tournament was the crossifre rule. I was shooting at a swarm within some buildings. I had another formationon the opposit side of the buildings. That formation was within 45 cm from my shooters but beeing on two sides of said buildings couldn't see each other.
My opponent then said I couldn't claim crossfire because my two formations couldn't draw a line of fire to each other. I looked up the rule and showed it to him. I can't see any such requirement in the rule and he couldn't either so I was alowed the use the crossfire bonus.
Was that the right interpretation or did we miss something? I have quoted the rule below (highlighted the most relevant parts). It only says I have to draw a straight line between my formations, but nothing about the shooting and friendly formation having to actually see each other.
Line of fire is only mentioned ones in the rule but that is in regard to the enemy formation being shot at.

1.11 CROSSFIRE
Formations that take fire from the flank or rear are caught in a deadly crossfire, and will suffer additional casualties as troops struggle to find cover from attacks coming from an unexpected direction.
To represent this, formations are allowed to use the following rules to claim a crossfire bonus when they shoot. You can claim the crossfire bonus if you can draw a straight line up to 45cm long from any of the units in the shooting formation to any unit in another friendly formation and this line crosses a unit from the target formation or the gap between two units from the target formation.
The friendly unit that the crossfire line is drawn to must have a line of fire to a unit from the target formation, but does not have to be in range with any of its weapons. You may not use units that are in broken or marching formations to claim the crossfire bonus.
There's nothing in the FAQ
(tournament pack 2013-08-07) mentioning the requirement of line of fire either when I checked.
