MJOLNIR power supply control unit

"Let's not even talk about the power supply..."

- Cairo Station's Master Gunnery Sergeant, reviewing the damaged components of John-117's Mark V MJOLNIR armor.

The power supply control unit is a component of the MJOLNIR Powered Assault Armor.

Description
The power supply control unit is integrated into the miniature fusion reactor located on the back of the MJOLNIR suit. It provides power distribution to the suit's functions and can be overloaded when too much power is allocated to one function or all functions for long periods of time. An example would be overcharging the shields, getting them drained, and then recharging them over a sustained period, such as when John-117 fought the overwhelming Flood for days during the Battle of Installation 04. While fitting the Master Chief with new armor on Cairo Station, an unnamed gunnery sergeant suggested that the power supply to his suit had sustained heavy damage from his use of it.

Destroying or disabling the control unit will instantaneously render the armor inert. This was demonstrated during the crisis on Gao in July 2553, after Special Inspector Veta Lopis detonated a small explosive she had placed in the power supply control unit of Fred-104's Mjolnir armor, leaving the suit entirely without power.
