The acquisition process is a series of progressive andinterdependent steps (or actions): detection, location,identification.

•Crew and Squad Search/Detect -Ground search -Air search

•Locate -Target direction -Target range

•Target Identification -Classify -Identify -Discriminate

ACQUISITION PROCESS

TARGET SEARCH

PROCESSACQUISITION

Crew and squad search (observation) is theact of carefully watching designated areas.Sectors of observation are assigned by the BCto each crew member and fire team memberfor target acquisition.

RAPID SCAN--- is usually the first method used, moving or not

---quickly detect obvious signs of enemy activitynote: scan starting from center sector, from near to far

- Optics or the naked eye may be used

GROUND SEARCH TECHNIQUES:

PROCESSACQUISITION

RAPID SCAN

PROCESSACQUISITION

SLOW(50meter)SCAN--- If no targets are detected in rapid scan crew and squad members conduct a more deliberate search. Slow scan follows the rapid scan, and is a more deliberate scan of the terrain.

--- optics are always used for this technique ( ISU, Bino’s) note: scan starts from left to right overlapping the first scanned area

in 50 meter increments best used when in a defensive position or from a short halt

DETAILED SEARCH---is the third search technique when no targets have been detected during the rapid and slow (50meter) scan

---the crew concentrates on one specific area or location and studies that area intensely.

---they look for direct and indirect target signatures in a clockwise manner around the focal point of the sector

AIR SEARCH TECHNIQUES:FLAT TERRAIN SCAN -Crews search the horizon using

short movements from object to object more detail is seen this way than with a continuous scan of the horizon

HILLY TERRAIN SCAN -Crews search the sky beginning just below the horizon and move upward. Crews use prominent terrain features to ensure overlapping search areas

PROCESSACQUISITION

NOTE: When conducting ground search, crews search near to far. When conducting air search, crews search far to near.

SEARCH TIPS

1. Initial scanning done without optics*All squad members should scan differentareas

2. Continuous search*Any targets missed on the first scan maybe seen in subsequent scans of the sector

3. Sectors of observation*All squad members must look for targets within their assigned sectors

4. Scanning on the move*The Gunner should use the rapid scan method

PROCESSACQUISITION

SEARCH TIPS

5. Turret optics adjustments*Gunner should adjust the reticle brightness,dome lights should be off, panel light dimmershould be adjusted. This aids the acquisition process.

6. BC’s sight extension*The BC’s sight extension should be coveredwhen not in use.

7. NBC operations The crew members’ fields of view are narrowedWhile wearing protective masks, scanning must be continuous.

PROCESSACQUISITION

SEARCH TIPS

8. Areas to search*The crew must search in areas where targets are most likely to appear.

PROCESSACQUISITION

ENABLING LEARNING OBJECTIVE

ACTION: Explain the elements of target detection.

CONDITIONS: Given a classroom, writing instrument, paper and FM 3-22.1.

STANDARDS: The student must correctly explain the elements of target detection.

TARGET DETECTION

Target detection is the discovery of any target

such as personnel, vehicles, equipment, or objects

of potential military significance on the battlefield.

Target detection occurs during crew search.

PROCESSACQUISITION

TARGET SIGNATURES

Target signatures are indicators or clues that aid an observerin detecting potential targets. The six signature types are.

•Soldier signatures

•Tracked vehicle signatures

•Antitank signatures

•Artillery signatures

•Aircraft signatures

•Obstacle and mine signatures

TARGET SIGNATURES

DETECTION CHALLENGES

•Peripheral targets

•Targets that are camouflaged or in shadows

•Targets that can be heard but not seen

•Targets under less than ideal indirect illumination

•Mirage effects caused by high temperatures and heat waves near the ground

•Small, single targets such as lone, dismounted ATGM or

RPG positions

•Natural or man-made obstacles

•Behavioral or physical deficiencies (Fatigue)

PROCESSACQUISITION

THERMAL SIGHTS

5 Sources of heat:

•Solar heat

•Fuel combustion

•Body heat

•Friction

•Thermal reflections

PROCESSACQUISITION

ENABLING LEARNING OBJECTIVE

ACTION: List the target location methods

CONDITIONS: Given a classroom, writing instrument, paper and FM 3-22.1.

STANDARDS: The student must correctly list the target location methods.

TARGET LOCATION

Target location is the determination of

where a target is on the battlefield. Locating a

target occurs as a result of observation and

detection during crew search.

PROCESSACQUISITION

TARGET DIRECTION

•Sector method

•Traverse method

•Reference point method

•Grid method (Least desired)

PROCESSACQUISITION

•Clock method

ENABLING LEARNING OBJECTIVE

ACTION: Define the two range estimation techniques.

CONDITIONS: Given a classroom, writing instrument, paper and FM 3-22.1.

STANDRDS: The student must correctly define the two range estimation techniques.

At times, because of the tactical situation, the BC or gunner may have to estimate range. These methods are used ONLY to estimate range. The two methods are:

RANGE ESTIMATION

PROCESSACQUISITION

100 meter unit-of-measure method-Visualizes 100 meter increments on the ground.

For ranges greater than 500 meters the crew member selects a point halfway to the object determines the number of increments to the halfway point and then doubles the range.

RANGE ESTIMATION

PROCESSACQUISITION

Flash to bang method -Multiply number of seconds from flash to bang by 350 meters

EXAMPLE: Two seconds between flash and bang2 x 350 = 700

ENABLING LEARNING OBJECTIVE

ACTION: List the methods of range determination.

CONDITIONS: Given a classroom, writing instrument, paper and FM 3-22.1.

STANDARDS: The student must correctly list the methods of range determination.

RANGE DETERMINATION

Range determination significantly affects

target engagement. Errors in range

determination (over/short of the target) cause

more first round misses than errors in

deflection (left/right of the target).

WHY IS THAT?

PROCESSACQUISITION

ENABLING LEARNING OBJECTIVE

ACTION: Define the three steps in target identification.

CONDITIONS: Given a classroom, writing instrument, paper, and FM 3-22.1.

STANDARDS: The student must correctly define the three steps in target identification.

TARGET IDENTIFICATION

Target identification is the recognition of a

potential target by type. This identification

must determine the target as friendly or

enemy. Target identification consists of:

PROCESSACQUISITION

• Classification

• Description

• Discrimination

CLASSIFICATION

Classification is the process of categorizing

targets by types (truck, tank, IFV). Soldiers

quickly scan the targets key recognition

features, and then categorize it accordingly.

Classification is the first step toward

identification.

PROCESSACQUISITION

IDENTIFICATION

Once a target has been classified, it must be

identified. Identification is the positive

determination of a target by nomenclature or

series (T-80, Scorpion series).

Note: Identification does not determine whether or

not a target is friendly or threat.

PROCESSACQUISITION

DISCRIMINATION

PROCESSACQUISITION

Discrimination is the determination that a target iseither friend or threat. Although Russian equipmenthas been sold in large numbers world wide, soldierscould find themselves facing British, French, andAmerican made equipment. It is critical that soldiersidentify and discriminate a target before pulling thetrigger.

Some tools and techniques available to soldiers to assist in target discrimination are:

•Combat identification panel (Battle board)•Battlefield Combat Identification System (BCIS)•Unit markings (VS-17 panel, chem lights,

unit symbols)

CHECK LEARNING

What is the Acquisition Process?Series of progressive and interdependent steps or actions: detection, location, identification

How many ground search techniques are there? And name them.

Rapid scan, slow(50meter)scan, deliberate search, off-center vision method

PROCESSACQUISITION

What are the two types of crew and squad target search techniques?

Ground search techniques and air search techniques.

ENABLING LEARNING OBJECTIVE

ACTION: Identify and define the steps in the engagement decision process.

CONDITIONS: Given a classroom, writing instrument, paper, and FM 3-22.1.

STANDARDS: The student must correctly identify and define the steps in the engagement decision process.

•Target determination

•Weapon / Ammunition selection

•Target confirmation

The engagement decision process is a series of progressive and interdependent steps (or actions):

ENGAGEMENT DECISION

TARGET DETERMINATION

Targets are categorized by the threat level

that they represent. To defeat multiple targets,

the most dangerous targets must be engaged

first.

DECISIONENGAGEMENT

TARGET THREAT LEVELS

•MOST DANGEROUS: Enemy target with armor defeating capabilities, that appears to be preparing to engage you.

•DANGEROUS: Enemy target with armor defeating capabilities that is not preparing to engage you.

•LEAST DANGEROUS: Enemy target that does not have an armor defeating capability.

DECISIONENGAGEMENT

DETERMINING FACTORS

When multiple targets of the same threat level are

encountered, the targets must be prioritized according to

the threat they represent. Factors used to determine

this are:

•Engage close-range targets before long-range targets.

•Engage stationary targets before moving targets.

•Engage frontal targets before flank or rear targets.

DECISIONENGAGEMENT

WEAPON / AMMUNITIONSELECTION

The logical selection of a weapon or

ammunition that is appropriate for a

given target.

DECISIONENGAGEMENT

TARGET CONFIRMATION

The rapid verification of the initial identification

and discrimination of the target.

* The Bradley Commander is solely responsible

for target confirmation.
