SECTION II. INTRODUCTION

Motivation           Use the following points to motivate the students:

· Ninety percent of first round misses are because the Bradley crew does not estimate range correctly.
· Knowing the components of the Bradley Eye-safe Laser Range Finder (BELRF) and their functions will   enable the students to use the capabilities of the BELRF.
· The students have already been introduced to some of the BFV-ODS improvements; during this lesson   they will learn to operate the BELRF.

Terminal               The terminal learning objective for this lesson is:
Learning
Objective

Action	Operate the Bradley Eye-safe Laser Range Finder,
Conditions	given the materials presented in this lesson,
Standards	and successfully complete 7 of the 10 checks-on-learning.

Instruction            GOOD MORNING, I AM ________________________________________.
Lead-in                 YOU HAVE ALREADY LEARNED ABOUT SEVERAL OF THE IMPROVEMENTS MADE                               TO THE BRADLEY FIGHTING VEHICLE AS A RESULT OF LESSONS LEARNED
                              DURING OPERATION DESERT STORM. INCLUDED AMONG THESE
                              IMPROVEMENTS IS A LASER RANGE-FINDING CAPABILITY KNOWN AS THE
                              BRADLEY EYE-SAFE LASER RANGE FINDER OR "BELRF."

Instructional         SHOW VGT BELRF-1, BFV-ODS Bradley Eye-safe Laser Range Finder.
Lead-in,
Continued             THE BELRF USES A LASER TO DETERMINE THE RANGE TO A TARGET. THE
                              BELRF TRANSMITS A PULSE OF LASER LIGHT, RECEIVES THE LIGHT REFLECTED
                              BACK, AND CONVERTS THE TIME FROM TRANSMISSION-TO-RECEPTION INTO
                              RANGE.

DURING GUNNERY EXERCISES, OVER 90% OF FIRST-ROUND MISSES ARE BECAUSE OF THE CREW’S INABILITY TO ESTIMATE RANGE CORRECTLY. THE BELRF AUTOMATICALLY DETERMINES ACCURATE RANGE TO TARGETS.

THIS LESSON TEACHES YOU HOW TO OPERATE THE BELRF PROPERLY.

Operation

THE ISU IS THE PRIMARY SIGHT UNIT ON THE BRADLEY ODS VEHICLES. IT ALLOWS FOR LOCATING, SIGHTING, AND TRACKING THE TOW MISSILE, 25mm GUN, AND 7.62mm COAXIAL MACHINE GUN. IT IS ALSO USED WITH THE BCIS.

WHEN THE TOW IS BEING FIRED, THE ISU DISPLAYS THE TOW RETICLE (CROSS HAIR). THE CROSS HAIR REPRESENTS THE ISU LINE OF SIGHT TO WHICH THE MISSILE IS GUIDED ONCE IT IS FIRED. CROSS HAIR PLACEMENT ON THE TARGET IS CRITICAL TO MISSILE ACCURACY.

                              FOR THE WEAPON SELECTED.

PUSHING (NOT PULLING) THE BELRF TRIGGER ACTIVATES THE BATTLEFIELD COMBAT IDENTIFICATION SYSTEM. THE GUNNER WILL BOTH SEE AND HEAR A SIGNAL INDICATING IF THE TARGET IS FRIENDLY OR UNKNOWN OR IF THERE IS A FRIEND IN SECTOR.

IF THE AMMUNITION INDICATORS BLINK, THE TARGETS ARE OUT OF MAXIMUM EFFECTIVE RANGE FOR THAT AMMUNITION.

Operator
Tasks--                 THE TENTH STEP IN THE BELRF OPERATION PROCEDURE IS TO CHECK THE
Operations-           RANGE STATUS INDICATOR.
Step 10

YOU LOOK INTO THE GUNNER'S EYEPIECE TO CHECK THE STATUS INDICATOR. IF THE FOUR-DIGIT DISPLAY BLINKS, INDICATING MULTIPLE RETURNS, THE COMMANDER SHOULD CHECK THE TARGET, ESTIMATE THE RANGE, AND DECIDE WHICH RETURN POSITION SHOULD BE USED. ALTERNA-TIVELY, HE MAY REPOSITION THE RETICLE ON THE TARGET AND LASE AGAIN.

BELRF
Information          THE FOLLOWING ADDITIONAL INFORMATION IS IMPORTANT TO THE
                             OPERATION OF THE BELRF.

·  TO FIRE IN THE GUN MODE, FOR BOTH THE 25mm AND THE COAXIAL    MACHINE GUN, THE DAY SIGHT BALLISTIC SHIELD DOORS MUST BE OPEN.

·  THE BELRF IS CAPABLE OF DETERMINING RANGE OF TARGETS 2.3 X 2.3    METERS AT RANGES FROM 200 TO 6,000 METERS. LARGER OBJECTS CAN BE    RANGED UP TO 9,990 METERS.

·  THE FOUR FAILURES NORMALLY EXPERIENCED DURING THE BUILT IN TEST    ARE REVIEWED AGAIN:

·  F1 - INDICATES PFN AND POWER SUPPLY FAILURE.

·  F2 - INDICATES TRANSCEIVER FAILURE.

·  F3 - INDICATES SUPERELEVATION FAILURE

·  IF ALL THE LEDs ARE OFF - INDICATES A TOTAL BELRF FAILURE.

·  THE MESSAGE "C024" INDICATES NO FAILURES WERE FOUND.

Additional            SHOW VGT BELRF-46, BELRF - Additional Information, Continued.
BELRF
Information,         ·  OUT OF RANGE INDICATION IS SET AT 900 METERS FOR 7.62mm, 1500 METERS
Continued                FOR THE 25mm GUN HE/AP, AND 2200 METERS FOR THE M919 ROUND.
                                 RANGING BEYOND THESE SETTINGS WILL RESULT IN A FLASHING AMMO
                                 INDICATOR FOR A 5-SECOND PERIOD. HOWEVER, FLASHING RANGE DOES
                                 NOT MEAN YOU CANNOT ENGAGE THE TARGET. MAXIMUM EFFECTIVE
                                 RANGES FOR ALL AMMUNITION STILL APPLY.

·  RANGE COMPENSATION FOR THE M919 ROUND IS SET BY SELECTING THE
   CENTER POSITION ON THE AP AMMO CAN SELECT SWITCH.

·  THE BELRF SYSTEM WILL NOT LASE IN THE TOW MODE.

·  MULTIPLE TARGETS AS CLOSE AS 20 METERS CAN BE DISCRIMINATED.

·  THE LASER IS CAPABLE OF CONTINUOUS FIRING FOR MORE THAN TWO    MINUTES.

·  WHEN THE BRST PRSM IS ENGAGED, THE TOW LIGHT COMES ON AND THE    LASER WILL NOT FIRE.

·  EXCESSIVE TURNING OF THE LASER BORESIGHT KNOBS WILL CAUSE LOSS OF    THE BORESIGHT RETICLE IN THE EYEPIECE DURING BORESIGHTING.
