1 BASIC RIFLE MARKSMANSHIP Instructor Name

2 TASKTASK Conduct Basic Rifle Marksmanship Training prior to scheduled zero and qualification range. Given a classroom environment, a knowledgeable instructor and highly motivated soldiers, ready to receive BRM instruction. To have a full understanding of the basic rifle marksmanship techniques and marksmanship fundamentals and employ them during the practical exercises and the qualification range. CONDITIONSCONDITIONS STANDARDSSTANDARDS

3 M4 RIFLE SYSTEM Consists of a Rifle, a Magazine, and a sling. It is a lightweight, gas operated, air cooled, magazine fed, semi- automatic and burst rate, shoulder fired weapon with a collapsible stock.

4 M4 SPECIFICATIONS Caliber: 5.56 mm Muzzle Velocity: 2,970 fps Weight: W/30 round magazine 7.5 lbs Cyclic Rate of Fire: rpm (approx.) Max Effective Range: 500M (Point)- 600M (Area) Max Range: 3600M Length: 29.75” to 33” Barrel Rifling: RH 1/7” twist

5 CLEAR THE WEAPON 1. Place the Weapon on SAFE 2. Remove the Magazine 3. Lock the Bolt Open 4. Check the Ejection Port and Chamber for ammo 5. With Selector Lever on SAFE, let the bolt go forward

6 DISASSEMBLYDISASSEMBLY 1. Clear your weapon. 2. Remove sling. CAUTION Do not use a screwdriver or any other tool when removing the handguards. Doing so may damage the handguard and/or slip ring. 3. Place the weapon on the buttstock and press down on the slip ring with both hands. 4. Have another a person pull the handguards free (the ‘Buddy System").

27 Pre-Marksmanship Training MARKSMANSHIP FUNDEMENTALS 1. Steady Position 2. Aim 3. Breathing 4. Trigger Squeeze

28 Steady Position Non Firing Hand : The rifle hand guard rests on the heel of the hand n the V formed by the thumb and fingers. The grip is light and slight rearward pressure is applied. Rifle Butt Position: The butt of the stock is placed in the pocket of the firing shoulder. This reduces the effect of recoil and helps ensure steady position

29 Steady Position Firing Hand Grip : The firing hand grasps the pistol grip so that it fits in the “V” formed by the formed by the thumb and forefinger. The forefinger is placed on the trigger so that the lay of the weapon is not disturbed when the trigger is squeezed Firing Elbow Placement: The location of the firing elbow is important in providing balance. The exact location, however, depends on the firing/fighting position used. Placement should allow shoulders to remain level.

30 Steady Position Stock Weld : The stock weld is taught as an integral part of various positions. Proper stock weld position should allow for correct sight alignment from the rear sight to the front sight to the target. Neck should be relaxed allowing cheek to fall naturally onto the stock. To begin proper stock weld, start by placing your nose on the charging handle when assuming a firing position. Non-Firing Elbow: The non-firing elbow is positioned firmly under the elbow to allow for comfortable and stable position. When the soldier engages a wide sector of fire, moving targets, and targets at various elevations, his non firing elbow should remain free of support.

31 Steady Position Support : If artificial support (sandbags, logs, stumps) is available, it should be used to steady the position and to support the rifle. If it is not available, then bones, not the muscles, in the firer’s upper body must support the rifle. Muscle Relaxation : If support is properly used, the soldier should be able to relax most of the muscles. Using artificial support or bones in the upper body as support allows him to relax and settle into position. Natural Point of Aim: When the soldier first assumes his firing position, he orients his rifle in the general direction of the target. Using proper support and consistent stock weld, the soldier, rifle and sight should align naturally on the target. As the weapon firers, the muscles tend to relax, causing the weapon to move away from the target toward the natural point of aim. Adjusting this point to the desired point of aim eliminates this movement.

32 AimingAiming Rifle Sight Alignment : Alignment of the rifle with the target is critical. It involves placing the front sight post in the center of the rear sight aperture. Any alignment error between the front and rear sight repeats itself for every ½ meter the bullet travels.

33 AimingAiming Focusing the Eye : A proper firing position places the eye directly on line with the center of the rear sight. When the eye is focused on the front sight post, the natural ability of the eye to center objects in a circle and to seek the point of greatest light. The firer must place the tip of the front sight post on the aiming point, but the eye must be focused on the tip of the front sight post. This causes the actual target to appear blurry, while the front sight post is seen clearly. This technique is used for two reasons: - Only minor error should occur since the error reflects only as much as the soldier determines the target center - Focusing on the tip of the front sight post aids in the firer maintaining proper sight alignment.

34 AimingAiming Sight Picture : Once the soldier can correctly align his sights, he can obtain a sight picture. A correct sight picture has the TARGET, FRONT SIGHT POST, and REAR SIGHT aligned. The sight picture includes two basic elements: sight alignment and placement of the aiming point.

35 AimingAiming Sight Picture : A technique to obtain a good sight picture is the side aiming technique. It involves positioning the front sight post to the side of the target in line with the vertical center mass, keeping the sights aligned. The front sight post is moved horizontally until the target is directly centered on the front sight post.

36 AimingAiming Front Sight : The front sight is vital to proper firing and should be replaced when damaged. Two techniques that can be used are the carbide land and the burning plastic spoon. The post should be blackened anytime it is shiny since precise focusing on the tip of the front sight post cannot be done otherwise.

37 Breath Control There is a moment of natural respiratory pause while breathing when most of the air has been exhaled from the lungs and before inhaling. Breathing should stop after most of the air has been exhaled during normal breathing cycle. The shot must be fired before any discomfort is felt.

38 Trigger Squeeze If the trigger is not properly squeezed, the rifle is misaligned with the target at the moment of firing. Rifle Movement : - Any sudden movement of the finger on the trigger can disturb the lay of the weapon and cause the shot to miss the target - The precise instant of firing should be a surprise to the soldier Trigger Finger : - The trigger finger is placed on the trigger between the first joint and the tip of the finger. The trigger finger must squeeze the trigger to the rear so that the hammer falls without disturbing the lay of the rifle. Proper trigger squeeze should start with slight pressure on the trigger during initial aiming process. More pressure is applied one front sight post is steady on the target and the firer is holding their breath.
