ICMC QUESTIONS AND ANSWERS | 2026 UPDATE | WITH COMPLETE SOLUTION.
What is C4I? - (ANSWER)We use COMPUTERS, connected to live COMMUNICATION circuits to either
send or receive COMMAND and CONTROL orders and operational INTELLIGENCE.
What is IT21? - (ANSWER)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". - (ANSWER)-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? - (ANSWER)CUDIXS
What are the IT21 Objectives? - (ANSWER)-Information superiority
-Network Centric Warfare
-Quality of Life
What is DISA? - (ANSWER)Defense Information System Agency. Provide C4I (NIPR, SIPR, JWICS, DSN,
DRSN, and JCA) to the war fighter, world wide.
What is FLTCYBERCOM/C10F? - (ANSWER)Central operational authority for networks,
cryptology/SIGINT, IO, cyber, EW, and space in support of forces afloat and ashore.
What is SPAWAR? - (ANSWER)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? - (ANSWER)Center for Information Dominance.
-Training for Information Dominance positions. i.e. IT's, CT's, IP officers......

Radio Frequency in general. - (ANSWER)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 - (ANSWER)High Frequency 3 - 30MHz
Long range Tactical Comms.
VHF - (ANSWER)Very High Frequency 30 - 300MHz
-LOS/ Bridge to Bridge
-Marines SINCGARS (30 - 88MHz)
-International Air Distress (IAD) and Military Air Distress (MAD)
UHF - (ANSWER)Ultra High Frequency 300 - 3000MHz (3GHz)
-UTILITY
-LOS and SATCOM voice/data/video
-Low = 75bps - Max = 2400bps
SHF - (ANSWER)Super High Frequency 3 - 30GHz
-CAPACITY
-Satcom = DSCS, CWSP internet
EHF - (ANSWER)Extremely High Frequency 30 - 300GHz
- SURVIVABILITY
- Highly Sensitive Comms / Tomahawk Strike Missions
- MDU, TIP / LDR, MDR
