2. INTRODUCTION The most common application of a patrol
harbour is the establishment of a Triangular
Harbour by a Platoon. This drill can also be
adapted by a smaller Patrol. A patrol
harbour is a defendable location in which a
platoon or section can administer
themselves prior to and during intensive
patrol activity.
3. AIM The aim of this lesson is to teach patrol harbour
drills so that by the end of the lesson you will know
the process of;-
Selection
Occupation
Clearance patrols
Sentries
Work routine
Security
4. REASONS FOR HARBOUR To avoid detection
To lie up whilst a Recce of an objective is made and issue of orders
A base from which Op’s can be mounted
Provide an RV after infiltration into enemy area or withdrawing from such an area
To provide security for admin (Long periods of movement / contact)
5. SELECTION Selection of a possible area can be done from
Map appreciation
Air photograph
Aerial photograph
From the ground
The detailed sighting must be confirmed by Recce and area secured before occupation
6. SELECTION CONSIDERATIONS Mission
Concealment
Easily defendable
Away from habitation
Away from steep slopes, valleys, re-entrants
Boggy or marshy areas
Obvious locations
Known suspect or previous locations
7. OCCUPATION Break track
Lay ambush – Pl Sgt
Recce Party go forward;-
Sect Comd’s
Radio Op
At least one guide
8. OCCUPATION Pl Comd points out HQ position
Sighting of Section Areas
LSW Positions
Perimeter wire
9. OCCUPATION Sect Comd and Guide sent to bring the main body into the harbour area
Sections are met at the apex of their location and each man put into position
Each man removes his pack and is stood-to
Noise is kept to a minimum
10. OCCUPATION Sect Comd’s are sited centrally within their sect positions so that they can see the Pl Comd and their 2IC’s
Pl Comd should check the perimeter to ensure cohesion between sections
11. CLEARANCE PATROLS Sect Comd or 2IC and 1 or 2 men
Move out through neighbouring LSW position
Back in through own LSW Position
Out to limit of visibility and sound
Move along their own section frontage
Remainder of the section are stood-to
12. CLEARANCE PATROLS The Sect Comd or 2IC and 1 or 2 men
Out through neighbouring LSW position
In through own LSW position
Limit of visibility and sound
Move along their own section’s frontage
13. CLEARANCE PATROLS Clearance Patrols are to detect and report the
following;-
Signs of enemy activity
Possible enemy approach routes
Streams and dominating ground
Unexpected obstacles (i.e. mines & ravines)
Possible ERV locations
14. SENTRIES Sentries posted beyond limit of noise from the harbour
One sentry per section posted in depth
Sentries are to act as early warning
Rifle is only to be used in self defence
Withdrawal route is via the LSW position
Sentries are to be clearly understood
15. SENTRIES Com’s cord from sentry to LSW position
Sentries are pulled in at night
Staggered double manning at night from LSW positions
Double manning provides continuity at the sentry post, allows one sentry to fetch relief and reduces the chance of a sleeping sentry
16. WORK ROUTINE Once sentries are posted work begins to
strengthen the harbour area;-
Preparation of stand-to positions
Shell Scrapes
Fields of fire
Warning devices (trip flares)
Track Plan (silent movement)
17. WORK ROUTINE Laying of coms cord from sentry to LSW position / Sect Comd
From Sect Comd to Pl Comd
Shelters erected over shell scrapes
Shelters erected at last light and taken down before first light
Shelters may be erected in poor weather at Pl Comd’s discretion
18. WORK ROUTINE Confirmatory orders by Pl Comd to establish
operational and admin routine. The points are
for routine in defence;-
Future Op’s (patrols)
Alarm Position
Orders for opening fire and defence
Location of Pl ERV
Stag list
19. WORK ROUTINE Re-supply (Ammo, Water and Rations)
Sleeping and feeding
Track discipline
Staggered cleaning of weapons
Latrines
20. SECURITY Pl Comd must ensure;-
Sentries are correctly posted and briefed
All round defence has been achieved
Good coms with sentries (early warning)
21. SECURITY Pl Comd must ensure that good battle discipline has been achieved;-
Camouflage and concealment
No lights or smells
No unnecessary noise
Webbing worn and weapons carried at all Times
Kit not in use is to be packed away
22. SECURITY The harbour area is to be as compact as possible
Clearance patrols at first and last light
All movement into the harbour through 6 o’clock position (or route taken during occupation)
Precautions taken to counter possible enemy follow up
23. SUMMARY Harbour drills can be summed up by
remembering the following General headings;-
Selection
Occupation
Sentries
Security
Work routine
