communications detachments on all naval communications matters. It also provides Naval Industrial Fund (NIF) AIS services to Navy customers.

NAVAL COMPUTER AND TELECOMMUNICATIONS DETACHMENT

A Naval Computer and Telecommunications Detachment (NAVCOMTELDET) is a small telecommunications facility that is assigned a limited, or specialized, mission and has a limited number of personnel and facilities.

NAVAL DATA AUTOMATION FACILITY

A Naval Data Automation Facility (NAVDAF) comes under the control of an NCTS or a NARDAC. NAVDAFs provide AIS services in areas where no NARDACs are located. The workload of a NAVDAF is normally less than that of a NARDAC. NAVAL SECURITY GROUP DEPARTMENTS

The Naval Security Group Departments (NAVSECGRUDEPTs) come under the authority of Commander, Naval Security Group Command (COMNAVSECGRU), and are responsible for the cryptologic and related functions of the Navy. NAVSECGRUDEPTs maybe part of a NCTAMS or a NAVCOMTELSTA. As such, COMNAVSECGRU exercises technical control over the cryptologic operations, whereas COMNAVCOMTELCOM has overall responsibility for the management and operating efficiency of the NAVSECGRUDEPTS.

MILITARY AFFILIATE RADIO SYSTEM (MARS)

A function of the Military Affiliate Radio System (MARS) is to provide auxiliary communications to military, civil, and/or disaster officials during periods of emergency. The Navy encourages amateur radio operators to affiliate with MARS. Many of the

operators have earned their amateur radio licenses from the Federal Communications Commission.

The amateur radio operators, using their amateur stations on Navy radio frequencies, receive training in naval communications procedures and practices. Besides assisting in emergency situations, MARS operators also create interest and furnish a means of training members in naval communications.
