Engaging Targets While Wearing the Field Protective Mask

While engaging targets in a combat environment, a Marine is under considerable stress caused by fear, fatigue, and the noise of battle. His stress is further aggravated by the fear and uncertainty associated with a nuclear, biological, and chemical (NBC) threat. However, a Marine must be able to operate under any battlefield condition, including an NBC environment. If a Marine wears the field protective mask, its bulk and reduced visibility can affect his firing position which in turn affects...

C Three Elements of a Good Shooting Position as they Apply with the Loop Sling There

13 are three elements of a good shooting position that apply when using a loop sling 14 (1) Bone Support. The body's skeletal structure provides a stable foundation to support the 15 rifle's weight. A weak shooting position will not withstand the repeated recoil of a rifle when 16 firing at the sustained rate or buffeting from wind. To attain a correct shooting position, the 17 bones of the body must support as much of the rifle's weight as possible. Proper use of the 18 sling provides...

Engaging Targets During Low Light and Darkness

Combat targets are frequently engaged during periods of darkness or under low-light conditions. Basic marksmanship fundamentals do not change, however, the principles of night vision must be applied and target detection is applied differently. During periods of darkness or low light, a Marine's vision is extremely limited. A Marine must apply the techniques of night observation in order to detect potential targets, and he must develop skills that allow him to engage targets under these...

Field Expedient Battlesight Zeroing

19 BZO is the elevation and windage setting established at 300 yards that enables a Marine to engage 20 point targets from 0-300 yards under ideal weather conditions. If a 300-yard range is not 21 available, a field expedient BZO can be established at a reduced range of 36 yards. When a rifle is 22 zeroed for 300 yards, the bullet crosses the line of sight twice. It first crosses the line of sight on 23 its upward path of trajectory at 36 yards, and again farther down range at 300 yards (see...

Figure Right Elbow

The placement of the shooter's cheek against the stock should remain firm and consistent from shot to shot. Consistency of stock weld is achieved through proper placement of the rifle butt in the pocket of the shoulder. A firm contact between the cheek and the stock enables the head and rifle to recoil as a single unit. This provides quick recovery between rapid fire shots, keeps the aiming eye centered in the rear sight aperture, and prevents the head from bouncing off the stock...

Factors Causing a BZO to be Reconfirmed

Marines are responsible for maintaining a BZO on their rifles at all times. Many factors influence the BZO of a rifle. If operating in a combat environment, Marines should confirm their BZO as often as possible. Atmospheric conditions, humidity, and temperature can cause BZOs to change on a daily basis. To confirm a BZO, a Marine may begin the zeroing process by using the previously established BZO sight settings rather than placing the sights at initial sight setting. The following factors...

A Temperature

32 1 Extreme changes in temperature cause fluctuation in the rifle's chamber pressure. This 33 fluctuation is caused by changes in the propellant's temperature. In cold weather, as rifle chamber pressure decreases, the bullet exits the muzzle at a lower velocity, and the bullet impacts the target below the point of aim. In extreme heat, the rifle's chamber pressure increases causing the bullet to exit the muzzle at a higher velocity and impact the target above the point of aim. Hot air is less...

Figure Clearing Barrel

On the command Load, the Marine will perform the following steps to take the rifle from Condition 4 to Condition 3 With a straight trigger finger, point the rifle in the clearing barrel. Ensure the rifle is in Condition 4. Withdraw a magazine from the magazine pouch. Ensure the magazine is filled. Fully insert the magazine into the magazine well. Without releasing the magazine, tug downward on the magazine to ensure it is seated. Close the ejection port cover. c....

Loop Sling

The loop sling provides the greatest amount of stability during firing. This stability allows the Marine to perfect marksmanship fundamentals. A loop sling takes longer to don or remove than a hasty sling. Therefore, it has limited combat application it is best used where stability of hold is needed for a precision or long-range shot. The loop sling is used in the prone, sitting, and kneeling positions. It provides maximum stability in all the supported firing positions.

Engaging Moving Targets

In combat, it is unlikely that a target will remain stationary. The enemy will move quickly from cover to cover, exposing himself for the shortest possible time. Therefore, a Marine must quickly engage a moving target before it disappears. a. Types of Moving Targets. There are two types of moving targets moving targets and stop and go targets. Moving targets move in a consistent manner and remain in a Marine's field of vision. A walking or running man is an example of a moving target. A stop...

Engaging Multiple Targets

When engaging multiple targets, a Marine must prioritize targets and carefully plan his engagements to ensure successful target engagement. Mental preparedness and the ability to make split-second decisions are the key to successful engagement of multiple targets. The proper mindset allows a Marine to react instinctively and to control the pace of the battle rather than just reacting to the threat. After the first target is engaged, a Marine must immediately engage the next target and continue...

Offset Aiming

The conditions of rifle fire in combat may not permit mechanical adjustments of the sights. To engage a target during combat, a Marine may be required to aim his rifle at a point on the target other than center mass. This is known as offset aiming. Offset aiming is used to compensate for the distance and size of the target, wind, and speed and angle of a moving target. There are two primary techniques for offset aiming point of aim technique and known strike of the round. a. Point of Aim...
