From the Ranged Combat rules, p.19:
Attacker may use Ranged Squads to Flank. Defending Friendly Squads being Attacked cannot participate in any sort of defensive Flanked Combat with other Squads.
I think I understand the first sentence. I have no idea what the second sentence means. Please help me understand.
That makes sense, but the second sentence needs the word "Ranged" somewhere in it. It's not clear to me whether it's talking about:
(1) other squads adjacent to (and allied to) the squad being attacked at a range;
(2) other squads with range capability separated from (and allied to) a squad being attacked in melee; or
(3) something else I haven't considered.
