EXW QUESTIONS AND ANSWERS
110.1 Discuss the following security zones and factors that can effect zone
size/location.
[Ref. g, Ch. 6, Pg. 6-2 thru 6-3] - Answer -Security zones are established to provide
protection to HVAs and to control civilian/commercial vessel traffic in a designated area.
As a general rule, DOD has authority over security zones outside of U.S. Government
jurisdiction and the USCG has authority over security zones within areas of U.S.
Government jurisdiction. They are configured to protect stationary HVAs (assets at
anchor, pierside, or ashore) and underway HVAs. Tactical security zone configuration
and naming conventions are shown in Figure 6-1. Security zone is an overarching term
and inclusive of the following three zones:
1. Reaction Zone
2. Intercept Zone
3. Assessment Zone.
6.3.1 Reaction Zone
Ideally, the reaction zone extends at least 1,000 yards/meters from the HVA. The
reaction zone is where unidentified or potentially hostile contacts are engaged with
increasing levels of force until they retreat outside of the zone or are no longer a threat.
Potentially hostile threats are not allowed to approach the HVA inside this minimum
distance. Any vessel traffic in this zone must be kept under positive control. The actual
distance for this zone may be based on the FPCON in effect for that AO. Any attempt to
penetrate the reaction zone, after being warned off by security boats, could constitute
hostile intent.
6.3.2 Intercept Zone
Ideally, the intercept zone extends at least 1,000 yards/meters from the outer boundary
of the reaction zone away from the HVA. This zone is established to increase the time
to react to a threat. Screening vessels (SVs) patrol this zone and intercept COIs
entering this zone to determine their intent. Vessel traffic in this zone is controlled.
Personnel, vehicle, and vessel access control points may be constructed to control
shoreside and waterside access from outside the perimeter to this zone. The actual
distance for this zone m
.2 Discuss the following factors that determine navigability of waterways. [Ref. h, Ch.
5.4.1, Pg. 5-2 thru 5-3] - Answer -a. Currents
The river current along a route has a significant effect on fuel consumption and speed
capability, anchoring, craft orientation, and tactical operations.
b. Depth of Waterways
The depths of the various waterways in a riverine AO affect route selection as well as
anticipated speed of advance.
c. Water Levels
In most riverine areas, water levels are an important factor in riverine movement
planning and execution. Vertical datum for navigation charts and water-level gauges are
the same. For safety, chart datum display depths on a navigation chart from a low-water
surface or a low-water datum. On most lakes, chart datum adopts a single level surface
, over the whole lake. Along a river, chart datum is a sloping surface that approximates
the slope of the river surface under low-water conditions. Ideally, water levels on a lake
or river will seldom fall below its chart datum elevation and only rarely will there be less
depth available than what is portrayed on the chart. This is not always true, however, so
riverine forces must possess up-to-date navigation charts and know how water levels
compare to chart datum wherever they operate. In the absence of a local datum,
riverine forces should establish a local datum with a digital or manual measuring device.
d. Natural Obstacles
Natural obstacles in the riverine environment include floating debris, rapids/whirlpools,
low hanging branches and limbs, underwater stumps and roots, and sandbars.
e. Manmade Obstacles
Manmade water obstacles are numerous and can range in complexity and size from
simple fish stakes to earthen dikes. The enemy may place some obstacles designed to
damage craft or foul propellers just below the surface to avoid detection. If possible,
aircraft should conduct an aerial visual/electro-optical reconnaissance of the intended
route at both low a
.3 Discuss the following:
a. Guard Mount [Ref. f, Ch. 7, Pg. 7-12 thru 7-13] - Answer -Guard mount procedures
standardize watch turnover between oncoming and offgoing personnel. A thorough
guard mount is key to establishing the proper mindset in watch standers. The supervisor
must be completely familiar with all matters directly related to the watch, and ensure all
personnel are briefed and fully prepared to assume duties. Command-specific guard
mount procedures may amplify the specific procedures listed below.
Procedures that ensure an orderly turnover include the following:
1. Develop a ready-reference binder to contain:
a. General/special orders
b. Standard equipment checklist
c. Communication plan
d. Report formats
e. ROE/RUF
f. Intelligence information
g. Post-specific information.
2. Develop a guard mount logbook to record:
a. Changes to ROE
b. Watch events
c. Equipment turnover
d. Changes to information in the ready-reference binder.
Brief and Inspection
Prior to commencing watch turnover, oncoming watch standers should attend a guard
mount brief and inspection.
The COG, or designated supervisor, conducts the briefs and inspection. A standard
brief should include:
1. ROE/RUF guidelines
2. Status-of-forces agreement
