Shrapnel NMG

 was an active ability available to the Heavy Assault. It was unlocked and upgraded using Certification Points.

When activated, the ability presumably applied an absorption overshield to the user, consuming energy to absorb damage. The ability was to be more efficient when used to absorb damage from Anti-Personnel Explosives, and less effective against other sources of damage.

This ability was never available for acquisition, and only appeared locked in the certification menu.
