My bad - didn't read close enough. Yea, that is a question. I would only guess it is a specific member of the team giving orders.
Q did say there are less than 10 and only 3 who are not military. So I interpret that to be 3 (including POTUS) who are civilians and 2 and upto 6 who are M. 5-9 either on the team or know of the team.
