ICMC EXAM QUESTIONS AND
ANSWERS 100% PASS 2026/2027
What is C4I? - ANS We use COMPUTERS, connected to live COMMUNICATION circuits to
either send or receive COMMAND and CONTROL orders and operational INTELLIGENCE.
What is IT21? - ANS An information transfer strategy that currently leverages off of
acquisition programs to provide an integrated, coordinated end-to-end warfighting capability.
What are the weaknesses of "LEGACY" design? aka "STOVEPIPE". - ANS -Specialized circuit
-Specialized purpose
-Can't be shared; very inflexible
-Very bandwidth inefficient. 2400bps
-Not using "open" standards. cannot use commercial products on the Military Circuit.
Type of "LEGACY" design? - ANS CUDIXS
What are the IT21 Objectives? - ANS -Information superiority
-Network Centric Warfare
-Quality of Life

, What is DISA? - ANS Defense Information System Agency. Provide C4I (NIPR, SIPR, JWICS,
DSN, DRSN, and JCA) to the war fighter, world wide.
What is FLTCYBERCOM/C10F? - ANS Central operational authority for networks,
cryptology/SIGINT, IO, cyber, EW, and space in support of forces afloat and ashore.
What is SPAWAR? - ANS Space and Naval Warfare Systems Command.
It provides the systems/equipment to meet the requirement. PMW 130 = IA; PMW 150 =
Command and Control; PMW 160 = Networks and Ent. Services; PMW 170 = Communications
What is CID? - ANS Center for Information Dominance.
-Training for Information Dominance positions. i.e. IT's, CT's, IP officers......
Radio Frequency in general. - ANS The lower the frequency, the longer the wavelength, and
the Bigger the antenna must be to radiate the signal.
The higher the frequency, the shorter the wavelength, the higher the B.width, and the more info
that can be encoded on the wave.
HF - ANS High Frequency 3 - 30MHz
Long range Tactical Comms.
VHF - ANS Very High Frequency 30 - 300MHz
-LOS/ Bridge to Bridge
-Marines SINCGARS (30 - 88MHz)
-International Air Distress (IAD) and Military Air Distress (MAD)
