TBS PHASE 4 EXAM SCRIPT 2026
QUESTIONS AND ANSWERS GRADED A+
●● TBS-ATFP-2101a Given a terrorist threat, identify physical security
measures to protect an
installation from terrorist attack.
Answer: Passive Security Measures: Require considerable effort to
establish, but once in place require few, if any, Marines for
support. Several of these measures are obstacles including:
Barriers: most common passive security measure; either
natural or manmade.
Fences: define a perimeter, canalize, and limit access
points. To maximize the effectiveness of a fence, clear
zones are generally established inside and outside the
perimeter to deny the enemy cover and concealment while
providing security forces with good fields of fire.
Alarm systems: provide extensive surveillance while
economizing manpower
Lighting: employed to increase the risk to the intruder;
eliminating the cover of darkness will restrict the enemy's
free movement. Effective lighting can also provide
concealment for security forces.
, Active Security Measures: Patrols to detect, deter, apprehend,
and/or destroy the enemy. Depending on the environment, rules
of engagement (ROE) are likely to be an overriding concern.
Ensure that all members of your unit understand and adhere to
ROE. Sentries provide access control, surveillance, and random
searches. When an interior guard is established, attention must
be paid to guard orders and passive measures which will support
the sentry. "Guardian Angels" utilize armed personnel in
positions of over watch, providing the ability to identify and if need
be, engage threats.
