Command Network Module
From Halopedia, the Halo wiki
The External Command Network Module or CNM, is an external attachment to MJOLNIR Powered Assault Armor helmets.[1]
Two different models are known, one designed for the Military Police helmet and the other for the Mark V[B] helmet. The former is standard issue to Special Force unit commanders, while the latter is used by Beta-5 Security units patrolling the Inner Colonies.[1]
The CNM is available as a helmet attachment in Halo: Reach.
