TBS PHASE 3 STUDY EXAMS GUIDE ALL QUESTIONS
AND ANSWERS SET A+
✔✔Probable Line of Deployment - ✔✔Designated line for a unit to deploy into assault
formations prior to beginning an assault.
As close as possible without detection, in obstacle belt.
Preferably located on a recognizable linear terrain feature.
Provides platoon with direction, does not need to be covered and concealed position,
ideally placed on terrain that prevents discovery.
✔✔Platoon Patrolling Operations - ✔✔- When you are in a high threat area longer than
you expected.
- Establish a secure area to stay combat effective
- Temporary defensive position
✔✔Things Required for a Patrol Base Site - ✔✔- Communications
- Little value to the enemy
- Off main lines of communications
- Away from populated areas
- Concealed from ground & air
- Near a water source
- Defendable for a short period
- Easy routes of egress
✔✔Patrol Base Sequence of Events - ✔✔Selection, Occupation, Security Patrol,
Sentries, and Work Routine
✔✔Patrol Base Selection - ✔✔1) LR - Plt Com, Sqd Leader, guides, GOTWA before
moving to site
2) Reconnaissance party sites & marks quad positions & apexes
,3) Guides return to main body, squad leaders stay at 6 o'clock position to guide in main
body.
✔✔Patrol Base Occupation - ✔✔1) Enter through the 6 o'clock position
2) SL place their Marines in pairs
3) Belt fed weapons placed on apexes to provide 360 security
4) 10 o'clock to 2 o'clock facing most likely enemy avenue of approach
5) Plt Com will cosign assign each squad an apex to man
6) 30 min stand-to SLLS
✔✔Patrol Base Security Patrol - ✔✔- O/S each squad pushed tow marines to the limit of
sight & sound - looking for RP, dead space, water, obstacles.
✔✔Patrol Base Sentries - ✔✔- must be posted to provide security for the platoon as
they begin work routine.
a) Inner Sentry Position - permanently occupied with belt fed weapon system, provides
depth and firepower to by time for the rest of the platoon.
b) Outer Sentry Position - LP/OP (platoon's early warning) Collapsed at night.
✔✔Patrol Base Work Routine - ✔✔1) Priorities of Work - Sentry positions
2) Preparation of stand to positions
3) Track Plan - cleared of obstacles & 550 cord tied around perimeter to the inner sentry
position
4) Plt Commander brief squad leaders on actions on contact and location of primary and
alt rally points
5) Personal admin once all platoon tasks are complete
Marines -> Wpns -> Gear -> Position -> Self
✔✔Patrol Base Self Care - ✔✔Dress into dry kit, eat, dry and wash body, clean wounds,
foot care, treat open wounds, wash face, brush teeth, shave, rest and recover.
✔✔Patrol Base - Hasty - ✔✔Same principles apply as deliberate, except: No LP/OP,
security patrols, or work routine. Situational awareness sacrificed to increase stealth.
✔✔Actions on Contact in the Patrol Base - ✔✔Stand, fight, and look to repel. No firing
takes place across the PB. Once repelled, collapsing PB and stowing of personal kit
done on a 50/50 basis. Once all marines are ready to move, squad move towards rally
point from the 6 o'clock position. Speed is of the essence but not at the expense of
being tactically sound. The squads not engaged will pack kit.
✔✔Primary Role of Engineer in the Defense - ✔✔1) Impede the mobility of the enemy
2) Field Fortification
3) Provide general engineering tasks to amplify sustainability of supported unit.
, ✔✔Battlefield Functions in the Defense - ✔✔1. Counter-Mobility.
2. Survivability.
3. Mobility.
4. General engineering
✔✔Mobility - ✔✔Mobility is a quality or capacity of military forces which permits them to
move from place to place while retaining their primary mission. Mobility support assists
forces to move rapidly, mass, disperse, and be resupplied. Engineers conduct the
following mobility tasks in the defense:
- Prepare counterattack routes clear of obstacles and/or have prepared breaches.
- Prepare combat trails for counterattacks and lateral movement between battle
positions.
- Prepare lanes and gaps through obstacle zones and belts.
- Reduce obstacles created by enemy fires and sabotage.Clear landing zones for
resupply and medical evacuations (MEDEVACs).
✔✔Counter-Mobility - ✔✔The primary intent of counter-mobility operations is to deny
the enemy's ability to execute his plan by:
• Disrupting his combat formations.
• Interfering with his command and control.
• Creating a vulnerability that friendly forces can exploit.
The secondary intent is to destroy or disable his vehicles. Engineers conduct the
following counter mobility tasks in the defense:
• Development of the obstacle plan to support the maneuver commander's concept of
operations.
• Assist in the installation and recording of minefields.
• Provide technical assistance and supervise the construction of specific obstacles.
✔✔Survivability - ✔✔A key component of the defense, survivability includes all aspects
of protecting personnel, weapons, and supplies. The objective of survivability is to
reduce exposure to threat acquisition, targeting and engagement, and the effects of
weather and thereby contribute to a successful defense. Depending on the priority of
work and engineer assets available, engineers will provide technical assistance or
assist in constructing:
Foritications:
- Anti armor an crew served weapon positions (hot and cold)
- Armored vehicle positions (hull defilade vs turrent defilade)
- Hardend command posts and combat support positions
✔✔General Engineering - ✔✔Those engineer tasks that establish and maintain the
infrastructure required to conduct and sustain military operations.
Engineers also conduct the following general engineering tasks in the defense:
