Cycle Of Functioning

The gunners can recognize and correct stoppages when they know how the M249 machine gun functions. The weapon functions automatically as long as ammunition is fed into it, and the trigger is held to the rear. Each time a round is fired the parts of the weapon function in a cycle or sequence. Many of the actions occur at the same time. These actions are separated in this manual only for instructional purposes. a. The cycle is started by putting the first round of the belt in the tray groove or...

Respect To Target

Fire with respect to the TARGET includes frontal, flanking, oblique, and enfilade fires. a. Frontal Fire.Frontal fire is when the long axis of the beaten zone is at a right angle to the front of the target. An example is when firing at the front of a target (Figure 5-4). b. Flanking Fire. Flanking fire is firing at the side of a target (Figure 5-4). Figure 5-4. Frontal fire and flanking fire. Figure 5-4. Frontal fire and flanking fire. c. Oblique Fire. Oblique fire is when the long axis of the...

Left Five Meters Drop One Hundred Meters

Fire commands need not be complete to be effective. In combat, the leader gives only the elements necessary to place fire on a target quickly and without confusion. During training, however, he should use all of the elements to get gunners in the habit of thinking and reacting properly when a target is to be engaged. After the gunner's initial training in fire commands, he should be taught to react to abbreviated fire commands, using one of the following methods....

Description

The M240B is a general-purpose machine gun. (Figure 3-1) It can be mounted on a bipod, tripod, aircraft, or vehicle. The M240B is a belt-fed, air-cooled, gas-operated, fully automatic machine gun that fires from the open bolt position. Ammunition is fed into the weapon from a 100-round bandoleer containing a disintegrating metallic split-link belt. The gas from firing one round provides the energy for firing the next round. Thus, the gun functions automatically as long as it is supplied with...

Warning

The M240B is carried loaded with the bolt locked to the rear in tactical situations where noise discipline is critical to the success of the mission. Trained gun crews are the only personnel authorized to load the M240B and only when command directs the crew to do so. During normal training exercises, the M240B is loaded and carried with the bolt in the forward position. e. Sight Setting and Sight Change Exercises. These exercises are designed to train the gunner in the operation and adjustment...

Mounting And Zeroing The Anpvs

Zeroing aligns the AN PVS-4 to the M249. The sight may be zeroed during daylight or darkness. (See TM 11-5855-213-10.) If done during daylight, the daylight cover must be used. To obtain a precise zero, it is best done at 300 meters and at night. Once an AN PVS-4 has been zeroed on an M249 machine gun, any soldier who knows how to use the reticle should fire the weapon effectively. However, there may be some changes in zero when the objective focus is adjusted to engage targets at various...

Reference Knockedout Tank Left Two Fingers Target Troops Three Hundred

This element includes manipulation and rate of fire. Manipulation prescribes the class of fire with respect to the weapon. It is announced as FIXED, TRAVERSE, SEARCH, or TRAVERSE AND SEARCH. Rate controls the volume of fire (sustained, rapid, and cyclic). Normally, the gunner uses the sustained rate of fire. The rate of fire is omitted from the fire command. The method of fire for the machine gun is usually 3- to 5-round bursts (M249) and 6- to 9-round bursts (M60 M240B).

A Bipod

When firing unassisted, changes in head position and stock weld are necessary especially when using weapon-target alignment techniques. Normally, the gunner positions his head so that he can align the weapon on the target and look over the sights. In some cases, the lower part of his jaw makes firm contact with his nonfiring hand on the stock, with his eyes an inch or so above the sights. The key is to use the natural pointing ability to align the machine gun on the target....

Reloading

The gunner must reload rapidly to avoid lulls in the firing. This can be achieved by practicing and by applying the following techniques. a. Before the assault, the gunner conducts prefire checks on the machine gun. He inspects ammunition to ensure that it is clean and serviceable, and he checks the box for serviceability. b. During the assault, the gunner must continue moving forward and reload as rapidly as possible. The sling allows the gunner to reload using both hands. This chapter helps...

Removal of the buffer, operating rod, and bolt assemblies. Figure 2-10. Removal of the buffer, operating rod, and bolt assemblies. c. Removing the Cover, Hanger and Cartridge Feed Tray Assemblies. The gunner uses a cleaning rod to unlatch the hook of the hinge pin latch. He removes the hinge pin latch and cover hinge pin. He removes the cover assembly, torsion spring, and hanger and cartridge feed tray assembly (Figure 2-11).

Bore Light

The bore light is an accurate means of zeroing weapons and the most aided vision equipment without the use of ammunition. Time and effort are applied to ensure a precise boresight, which in turn saves time and ammunition. Table G-1 outlines weapon aided vision device combinations that can be zeroed using the bore light with the M249 M60 M240B weapons. With optics, a 25-meter zero must follow boresighting. The precise boresighting of a laser allows the soldier to directly engage targets without...

Installtion

The M145 straight telescope mounts directly to the mounting rail on the M249, and M240B machine guns. It is necessary that you adjust the position of the M145 telescope either backwards or forward on the rail in order to achieve the correct eye relief (distance of the eye from the back of the telescope). If the same sight is installed in the same position slot on the rail on the same weapon, rezeroing is not required. a. Back off on the torque limiting knob just enough for the rail grabber to...

Stabilize

Stabilization of the weapon is crucial. The weapon can be stabilized on a tripod or using the bipod as a field-expedient method. The weapon does not have to be perfectly level with the ground when boresighting the weapon. Every barrel is different therefore, with every weapon, steps (d) through (f) must be done to ensure that the bore light is zeroed to that barrel. If the bore light is zeroed, then go directly to the boresighting procedures. a. Attach the 5.56-mm or 7.62-mm mandrel to the bore...

Always assume that weapons are loaded until they have been thoroughly examined and found to contain no ammunition and barrel is clear. c. Mark firing limits with red-and-white-striped poles that are visible to all firers. d. Never place obstructions in the muzzles of...

Marksmanship Fundamentals

The four fundamentals for firing are the same for all machine guns, they are steady position, aim, breath control, and trigger control. a. Steady Position. In automatic fire, position is the most important aspect of marksmanship. If the gunner has a good zero, correctly aims his weapon, and properly applies a steady hold in firing a burst of automatic fire, the first round of that burst hits the target at the point of aim. However, this procedure is not necessarily true of the second and third...

The leader should describe it briefly. If the target is obvious, no description is necessary. (4) Range. The leader always announces the estimated range to the target. The range is given, so the gunner knows how far to look for the target and what range setting to put on the rear sight. Range is announced...

B Conduct

(1) The gunner is given the command to aim at vertical line B and horizontal line 4. The next command is RIGHT 150 mils ADD 50 mils. The instructor then asks the gunner where he is aiming. (2) Lay on the horizontal line 15 and vertical line O. The next command is, LEFT 100 mils ADD 10 mils. The instructor then asks the gunner where he is aiming now. (3) The leader or instructor can have as many of these types of questions set up, until he feels the gunner is proficient at this task.

Transition Fire Limited Visibility

Night or limited visibility firing requires the soldier to apply the fundamentals of gunner marksmanship while using nightsights. This training instills confidence in the machine gunner. Each soldier learns how to engage targets using nightsight. He learns to mount the sight, boresight the weapon at 10-meters, and zero the aided vision devices (IAW Appendix G for that device) at 10-meters using a 10-meter (M16A2) zero target. Finally, he learns to detect and engage a series of undetermined...

To make minor changes in direction, the gunner shifts his shoulders to the right or left to select successive aiming points in the target area. Major changes require him to redistribute his weight to his elbows and toes and raise his body off the ground. Using his toes, he shifts his body to the right or left to be in the opposite direction of the target, and pivots on his elbows until he is aligned with the target. The gunner rapidly assumes a steady position, obtains the proper...

Program Phases

Since firing is a learning process, certain prerequisites must be satisfied before a trainer passes from one phase of marksmanship to another. The trainer must qualify with the machine gun (the trainer must pass all tasks and qualify on the 10-meter and transition fire) that he will be teaching to the machine gunners in his unit. To obtain maximum results on the battlefield, the machine gunners are trained in the fundamentals before they engage a combat target. The phases of the...

Assistant Trainers And Cadre Coaches

Assisting the trainer and coaching a soldier to fire the machine gun are highly technical jobs that must be done well. The most valuable soldiers in the program are those who not only have obtained a high standard, but those who can effectively teach this knowledge to others. Once the individual is consistent in this train-the-trainer program, he can then develop into a competent assistant trainer. It is worth the effort to train these individuals to become a successful assistant trainer,...

Section Vii Advanced Gunnery

Once the gunner masters the four fundamentals of marksmanship in the prone position and fighting position, he needs practice in engaging targets that will most likely replicate the battlefield. The advanced gunnery field firing exercise for the gunner exposes him to different types of targets at various ranges to simulate combat conditions. The objectives of this training are to reinforce the fundamentals and increase the effectiveness of the gunner by building his confidence (not for...

Ensure the reticle illumination switch is turned to the OFF position when not required.

Alternate Firing Positions

All gunners must master the bipod-supported prone firing fighting position, and tripod-supported prone firing position to be effective. But it is also equally important that they know other positions. Each gunner must be trained to assume different positions quickly during various combat conditions. The situation determines the appropriate position. The gunner must establish his position so that he can effectively observe and engage the target yet minimize his exposure to enemy fire. a....

Distribution Concentration And Rate Of Fire

The size and nature of the target determine how the gunner applies his fire. He must manipulate the machine gun to move the beaten zone throughout the target area. The rate of fire must be controlled to adequately cover the target but not waste ammunition or destroy the barrel. a. Distributed fire is delivered in width and depth such as at an enemy formation. b. Concentrated fire is delivered at a point target such as an automatic weapon or an enemy fighting position. c. The rates of fire that...

Machine Gun In The Attack

The potential increase of air and ground attacks on the unit demands every possible precaution for maximum security while on the move. Where this situation exists, the machine gun crew must be thoroughly trained in the hasty delivery of antiaircraft fire and of counterfires against enemy ground forces. The distribution of the machine guns in the formation is critical. The machine gun crew is constantly on the alert, particularly at halts, ready to deliver fire as soon as possible. If the leader...

Overhead Fire

Fire delivered over the heads of friendly soldiers is called overhead fire. It is used during training ONLY AFTER SOLDIER SAFETY IS CHECKED AND VERIFIED. The terrain and visibility dictate when overhead fire can be delivered safely. (See AR 385-63 for a complete summary of training safety requirements.) Overhead fire is delivered with any machine gun mounted on a tripod because the machine guns provide greater stability and accuracy, and because vertical mil angles can be measured by using the...

Engagement Of Moving Targets

The fundamentals used to hit moving targets are the same as those needed to hit stationary targets. However, the procedures to engage moving targets vary as the angle, speed, and range of the target varies. Targets moving directly at the gunner are engaged the same as a stationary target there is no change in the application of the fundamentals. But fast-moving targets at varying ranges and angles do require changes in the application of steady position and aiming. (For aerial targets...

The inspection of equipment for crew drill from the prone position is the same as that for bipod training and tripod training. b. Placing the Machine Gun Into Action. The leader...

Lateral Distance Measurement

In addition to estimating range accurately, the gunner needs a quick method of measuring lateral distance (right or left) from a reference point to a target. When the machine gun is tripod-mounted, width can be measured by aiming on a point, manipulating the traversing handwheel, and counting the clicks from one point of aim to another point of aim. Each click equals 1 mil and is equivalent to 1 meter at 1,000 meters, or half a meter at 500 meters. When the machine gun is bipod-mounted, the...

Field Zero

A gunner must know how to zero the machine gun at distance. He should select a known distance target between 300 and 700 meters. As the range increases, it becomes more difficult to determine where the center of the beaten zone is in relation to the target. Therefore, the 500-meter target on the transition range is recommended because of the ease of determining adjustments. a. Setting of the Sights. The gunner uses the same procedures as for 10-meter zeroing except that he places the rear sight...

Engagement Skills Trainer

The engagement skills trainer (EST) 2000 (Figure F-4, page F-6) is a home station, indoor, multipurpose, multilane, small arms simulator. The EST augments and substitutes individual, crew, and static-squad collective training.

Weaponry for the EST 2000 includes the M16A2 rifle, M4 carbine, M9 pistol,...

Cleaning Lubrication And Preventive Maintenance

The M249 machine gun should be cleaned immediately after firing. It should be disassembled into its major groups before cleaning. After it has been cleaned and wiped dry, a thin coat of CLP is applied by rubbing with a cloth. This lubricates and preserves the exposed metal parts during all normal temperature ranges. When not in use, the M249 should be inspected weekly and cleaned and lubricated when necessary. a. Cleaning. All metal components and surfaces that have been exposed to powder...

Danger Space

The danger space is the space between the machine gun and the target where the trajectory does not rise above 1.8 meters (the average height of a standing soldier). This space includes the area of the beaten zone. When the machine gun is fired on level or uniformly sloping terrain at a target less than 700 meters away, the trajectory does not rise above the average height of a standing soldier. When targets are engaged on level or uniformly sloping terrain at ranges greater than 700 meters, the...

Fire Commands

The standard fire commands are used as means of control during preliminary, basic, and advanced gunnery. The fire command must be explained to the gunner. The elements are given (as appropriate) before each dry-fire or live-fire exercise. The gunner takes action as directed and repeats each element as it is announced. (For a detailed explanation of fire commands, see Chapter 5.) When using the basic 10-meter range target, the fire command elements are as follows a. Alert. The alert is given as...
