Aircrew - responsible for the operation, maintenance, and troubleshooting of the radios, computers, antennas, networking, and cryptographic equipment on TACAMO and AWACS missions.

Seabee
Surface warfare - responsible for maintaining communication links, troubleshooting radio and computer equipment, satellite communications, cryptographic equipment, and is responsible for the administration of the shipboard LAN, WAN links, and servers/networking equipment.

Expeditionary Warfare
Fleet Marine Force - responsible for landing after the Marines have secured an area to set up fleet communications, networking, and cryptographic equipment to support joint communications within a battlefield environment.
