I am playing around with this unit, I figure even the Tau need help with comms on the battlefield be it from the senior officers directing the over all battle to the men or just where comms are bad

I was thinking that it will only carry a crew of 6 a driver and five radio operators in the back. It will loose the gun drones for comms drones that can be detached to allow comms to be reached in dead spots. It wll however still have a burst cannon for self defence.
The primary role for the unit is comms so it would be used in 1500+ battles
The points cost would maybe be 90-95 points and I was thinking about maybe making the positional relay rule of deploying on 2+ make it that if a roll is failed you get a re roll and allowing all reserves to deploy.
Please feel free to trow in any ideas
