TBS PHASE 1 EXAM UPDATED ACTUAL
Questions and CORRECT Answers
Given a tactical scenario with a mission and scheme of maneuver, select communication assets that will
enable command and control to support the scheme of maneuver.
What does FIRST-S Stand for in Communications? - CORRECT ANSWER o Flexibility
o Interoperability
o Reliability
o Security
o Timeliness
o Survivability
Given a tactical scenario with a mission and scheme of maneuver, select communication assets that will
enable command and control to support the scheme of maneuver.
Goal of Comms? - CORRECT ANSWER To manage massive flows of info IOT provide
commanders with only the info needed to be effective, while giving access to wider flows of info when
necessary.
Given a tactical scenario with a mission and scheme of maneuver, select communication assets that will
enable command and control to support the scheme of maneuver.
Role of Tactical Comms - CORRECT ANSWER Must be capable of facilitating speed and tempo,
while dealing with the problems of uncertainty and time. Ultimately, it must allow info to pass throughout
all levels of the MAGTF.
Given a tactical scenario with a mission and scheme of maneuver, select communication assets that will
enable command and control to support the scheme of maneuver.
AN/PRC 117F - CORRECT ANSWER VHF, UHF, and SATCOM Capable
, Highly Portable
VHF Range: 0-10Km
UHF Range: 20Km-LOS
Given a tactical scenario with a mission and scheme of maneuver, select communication assets that will
enable command and control to support the scheme of maneuver.
AN/PRC 152 - CORRECT ANSWER Highly Portable
Max effective range=5-7km
Given a tactical communications scenario, select the correct frequency spectrum to enable tactical
communications.
High Frequency (HF) - CORRECT ANSWER 2-29.99 MHz
Used for long distance comms when SATCOM is unavailable
Given a tactical communications scenario, select the correct frequency spectrum to enable tactical
communications.
Very High Frequency (VHF) - CORRECT ANSWER 30-89.99 MHz
Range extends slightly beyond Line of Sight (Approximately 50km)
Most widely used in Infantry Battalions for ground to ground comms
Given a tactical communications scenario, select the correct frequency spectrum to enable tactical
communications.
Ultra High Frequency (UHF) - CORRECT ANSWER 225-511.99 MHz
Used for ground to air comms
Range=Approximately 500km when communicating with aircraft if aircraft is within Line of Sight
Cannot bend around obstacles; therefore, is not good for ground comms
