110 Expeditionary Waterborne Fundamentals

Question 1

Reaction Zone

Answer 1

• 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.

Question 2

Intercept Zone

Answer 2

• 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.

Question 3

Assessment Zone

Answer 3

The outermost security zone for HVA protection and extends to the reach of organic and
inorganic sensors. This zone may be integrated into the overall defensive sea area force
protection plan.

Question 4

Discuss the following factors that determine navigability of waterways

Answer 4

Currents
Depth of Waterways
Water Levels
Natural Obstacles
Manmade Obstacles

Question 5

Guard Mount

Answer 5

A standardized watch turnover between on-coming and off-going watch
personnel. The supervisor must be thoroughly familiar with all matters directly related to the watch
and ensure all personnel are briefed and fully prepared to assume duties

Question 6

Five Paragraph Order

Answer 6

(SMEAC)

Question 7

Discuss waterborne threats

Answer 7

Small Craft
Aircraft
Deep Draft Vessels
Subsurface Threats
Swimmers / Divers
Mines and Improvised Explosive Devices

Question 8

Discuss the three types of Coastal Riverine Patrols

Answer 8

Reconnaissance
Security
Riverine Support

Question 9

Screening Vessel

Answer 9

The SV protects the HVA by determining a COI’s intent and proactively
screening and intercepting COIs in the assessment and intercept zones

Question 10

React Vessel

Answer 10

The primary role of the RV is to intercept, engage and, if necessary, destroy any
vessel attempting to enter a protected HVA’s exclusion zone.
