3.13 vs. 12.56 in 4th edition rules

[g1ul10]

Technically I don't think you need to designate the hex, but you would give the fire order and note they are assaulting. Sort of like with the move order, but actually rallying or digging in. That is why the activation loop in Vassal was setup the way it was.

Maybe it would be nice to have an "assaulting" icon in vassal to mark the "firing" units that are actually assaulting. Maybe a command that appears in the menu only when the unit is given the "fire" marker. This is clearly not a top priority, but I can try to modify the module and send it to you by email if you are interested to see a proof of concept.
