Earlier this morning, the Proton M ILV has been rolled out to the Fueling Station for loading the Breeze M low-pressure tanks with propellants.It should take several days to complete fueling operations and then the ILV should be moved to the Launch Pad.

IF Briz-M had a unified fuel system, then the 40 kg thrusters could be used as backup for the main engine in the event that the main engine should fail during orbital maneuvers.
If my memory is correct the deployment of the payload to a super-synchronous altitude from a Proton launch is a rare event. I think this might even be the highest super-synchronous altitude to be used on a Proton launch.
