My army list contains five Ghulams which I plan to put in a fireteam, a Ghulam Doctor who I plan to keep outside the fireteam, and a Nasmat servant peripheral which I plan to link to the Doctor. At deployment time, based on the situation on the ground I decide that I want to put the Doctor in the fireteam instead of one of the other Ghulams. This would leave the Nasmat without a controller. Can I do so, or am I required to deploy the Nasmat with a controller? If I'm allowed to put the Doctor in the fireteam, do I deploy the Nasmat in a permanently disconnected state, or leave it off the table?
