Coalition Headquarters

What I would like is to have a Coalition Headquarters which allows the owner to issue orders to coalition member units in a certain range. The HQ could then be increased by levels till you have Supreme Headquarters Allied Expedition Force (SHAEF).

It should be on its own little Tech Treat.

The other members of the Coalition would have to activate an allowance for the control and you would have to have only one HQ within its range. Players could then arrange a more effective and closer to realistic command structure and compensate for those who can be on line a lot as opposed to those that are on line for only 10 to 20 minutes twice a day.
