Having watched a few battles and the methods employed to command multiple
legions I've evolved 'COM' to allow for easier concurrent control of
more than one legion. You may have been using COM <commands> to send your
orders to your legion while at the commandpost. You can still use COM in
this fashion but you can also type COM <legion> <command> to send the
command to the selected legion, as a one off. This works when you are in
the same location as the designated legion, or if you're at the commandpost
of one legion and you wish to send a command to another legion nearby. I
suggest all those with an interest in military affairs experiment with
this to hone your skills on the battlefield.
