Sure, keep it to a minimum.
Seriously, I would love to be able to give orders to an HQ, (lets say Brigade) and then have the Battalions under that HQ react realistically based on their doctrine and the situation. One thing I do not like about most wargames is the amount of micro-management needed to play effectively. I have only played one game (Highway to the Reich - or HTTR) that deals with this problem effectively and realistically.
HTTR allows the player to give orders at any echelon, from Company (smallest element on the map) to the supreme HQ (usually Corps or Division level).. often I play somewhere in between, giving orders to Battalions and Brigades/Regiments.
