-And if the entire platoon seeks cover because of a pyrotechnic order will the ones that find it choose the same cover their fellows discovered?
-Can HQ's in cover command units out of cover and on the same card, or units in different cover on the same card?
- No. Seek cover and move to cover are different commands. Everybody will get running around and look for cover. Resolve in random order until all cover is found. This is why I worded my seek cover pyro "All lone quads without leader, seek cover." It just does not make much sense to have a platoon seek cover.
- No, they cannot. Except for cease fire/ shift fire, which is always performed by all units on a card regardless of command structure and communication. I am not sure about platoon moves, but I think they apply only to units in communication with the leader, i. e. under the same cover.
