Has the SecDef ordered it yet? Haven't seen it.
Question is, what goes down during the 10 days of darkness?
Whatever it is must be simple enough to promulgate the required orders that meet the mission requirements as laid down by SecDef. If the planning circle is small (as it most likely would be for something like this), the requirements would have to be relatively simple in order to make it happen quickly. Likely 'go here, on order do this'. The Reserves would be the backup follow on muscle.

My guess is will be used to backfill AD units that are performing operations.
