2-107. When conducting an area security mission, the battalion prevents threat ground reconnaissance 2004

elements from directly observing friendly activities within the area being secured and prevents threat ground 2005

maneuver forces from penetrating the defensive perimeters established by the commander. The commander may 2006

direct his subordinate companies to employ a variety of techniques such as observation posts, battle positions, 2007

ambushes, and combat outposts to accomplish this security mission. A reserve or quick reaction force (QRF) 2008

enables him to react to unforeseen contingencies. Using information collection and intelligence capabilities 2009

available to the battalion and BCT, the battalion can execute ambushes and preemptive strikes proactively and 2010

with great precision.

2011

2-108. An analysis of METT-TC determines the augmentation for the CAB. Particular consideration is given 2012

to the need for aviation, engineers, and artillery. Early warning of threat activity is paramount when conducting 2013

area security missions, and provides the commander with time and space to react to threats. Proper information 2014

collection planning, coupled with dismounted/mounted patrols and aerial reconnaissance, is key to successful 2015

operations, especially when securing fixed sites. Failure to conduct continuous reconnaissance can create a 2016

vulnerable seam through which the enemy can execute an infiltration or attack.

2017

2-109. A perimeter is established when a unit must secure an area where the defense is not tied into an 2018

adjacent unit. Perimeters vary in shape and distribution of assets based on the results of IPB and METT-TC. A 2019

most probable direction of attack may require extra “weighting” of that portion of the perimeter to defeat an 2020

attack or infiltration.

2021

2-110. Perimeters typically are divided into company/platoon areas with boundaries and contact points. The 2022

battalion establishes a screen by integrating observation posts, ground-based sensors, UAS, HUMINT, and 2023

mounted and dismounted patrols. Tanks, BFVs, and other antiarmor weapons systems (attached or organic) are 2024

emplaced on high-speed avenues of approach. Infantry and snipers can observe and cover dismounted avenues 2025

of approach. UAS and ground-based sensors provide overlapping information collection capabilities at extended 2026

distances from the perimeter. Figure 2-8 depicts a CAB conducting area security of a small village.

2027

2-111. Most circumstances will not permit establishment of defined, neat perimeters. When a perimeter is not 2028

feasible, the battalion secures the area by establishing a presence and conducting operations throughout the area.

2029

Subordinate units may establish perimeters around base camps, critical infrastructure, and high-value assets, 2030

while other units conduct operations to establish presence, provide security, assist the conduct of stability tasks, 2031

or provide the minimum levels of security, food, water, shelter, and medical treatment as described in ADRP 3-2032

07. The battalion may position reaction forces or disperse its reserve between several secured perimeters. (Refer 2033

to FM 3-37 for more information.) Other missions or tasks in support of area security may include the 2034

following:

2035

 Screens along zones of separation or other designated areas.

2036

 Route and convoy security of critical LOCs.

2037

 Checkpoint operations to monitor or control movement.

2038

 Demonstrations to maintain an observable presence.

Route Security 2042

2-112. Route security is a subset of area security. The purpose of route security is to prevent a threat from 2043

attacking, destroying, seizing, containing, impeding, or harassing traffic along the route. It also prevents the 2044

threat from interdicting traffic by emplacing obstacles on or destroying portions of the route. Route security 2045

operations are defensive in nature and, unlike screen operations, are terrain-oriented.

2046

2-113. Roads and railways may be mined; ambush sites can be located adjacent to the route being secured; or 2047

bridges and tunnels can be destroyed by demolitions. Because of the nature of this mission, very long routes 2048

may be extremely difficult to secure; however, measures can be enforced to reduce the effect of threat forces.

2049

(Refer to FM 34-22 for more information.) 2050

Route Security Methods 2051

2-114. The following discussion highlights three methods that the CAB can use in executing route security.

2052

The method the CAB chooses to use depends on the nature of the threat, purpose of the security mission, and 2053

characteristics of the route.

2054

2-115. In the first method, the battalion conducts route reconnaissance at irregular intervals to avoid 2055

developing a pattern that the threat may exploit. Companies reconnoiter the route, including conducting patrols 2056

to either flank. Attached aviation assets or UAS may reconnoiter in advance of ground units or assist in 2057

screening flanks. In addition to reconnaissance, companies or platoons may conduct combined arms operations 2058

with engineers conducting route clearance, or escort engineers conducting route improvements/maintenance;

2059

clearing terrain at potential ambush sites; and repairing damage caused by threat actions.

2060

2-116. The second method entails using an economy of force technique to protect only critical lengths or 2061

locations along the route. The battalion or company establishes mutually supporting combat outposts and 2062

provides security between them. The battalion or company establishes outposts at critical points to prevent 2063

sabotage and to defend against or respond to attacks to interdict the route between outposts. Based on METT-2064

TC, a company can establish one or two combat outposts, and a battalion typically can establish up to eight.

2065

Usually, the unit does not secure or patrol the route outside the reach of the combat outposts. A battalion can 2066

provide route security by combining this method at two locations or critical points with patrols along the rest of 2067

the route. Combat outposts should include a well-defined fire support plan. Battalion mortars or howitzer 2068

sections are positioned so they are capable of massing fires in support of both the outposts and the operations 2069

between them. Units conduct patrols at irregular intervals between the outposts based on threat trends and 2070

recent activities. Patrols must be organized with sufficient combat power to destroy near ambushes and to 2071

survive initial threat contact from far ambushes. Each combat outpost maintains a reaction force to respond to 2072

threat activity or reinforce patrols.

2073

2-117. The third method is one that the battalion uses if it must take actions to seize or secure terrain needed to 2074

permit use along the entire route. The battalion conducts an initial route reconnaissance, with follow-on units 2075

establishing a screen to either flank, checkpoints at access points to control access, and combat outposts at 2076

critical choke points. As time and forces allow, the battalion establishes defensive positions on key terrain, with 2077

subsequent positions prepared to support observation posts on the screen. It also establishes checkpoints at 2078

intersections, start points, and release points to monitor and control nonmilitary traffic. Checkpoints may also be 2079

established at irregular intervals so that troops can stop and search vehicles and personnel. Checkpoints should 2080

be situated along the route or in terrain that does not allow travelers to observe and turn away from the 2081

checkpoint holding area. As in the second method, the outposts established at critical choke points include 2082

sensors to provide early warning from immediate and surrounding areas. All positions must be defensible, with 2083

reinforced fighting positions. (See Figure 2-9a-e.) For this example, the BCT must provide the CAB with 2084

specialized combat engineer augmentation to perform the inherent route clearance task associated with route 2085

security.
