071-010-0006 (SL1) - Engage Targets with an M249 Machine Gun

Standards: Applied correct M249 machine gun target engagement techniques and hit each target in your assigned sector of fire.

Conditions: Given an M249 machine gun and linked 5.56-mm ammunition.

Standards: Applied correct M249 machine gun target engagement techniques and hit each target in your assigned sector of fire.

Performance Steps

1.   Assume a suitable firing position. Based on the situation, assume the position that will allow you to observe and engage targets, yet minimize your exposure to enemy fire.

a. Bipod-supported prone. The bipod-supported prone position (figure 071-010-0006-1) and the bipod-supported fighting position (figure 071-010-0006-2) are the best positions for delivering effective fire on targets. Assume these positions when possible.


Figure 071-010-0006-1. Bipod-supported prone position

 


Figure 071-010-0006-2. Bipod-supported fighting position

 

b. Shoulder.  Use the shoulder firing position (figure 071-010-0006-3)  to engage targets at ranges less than 100 meters when no other position can be assumed or when the situation dictates its use, for example in the final stages of the assault.


Figure 071-010-0006-3. Shoulder firing position

 

c. Underarm.  Use the underarm firing position when moving in and around the objective during the assault (figure 071-010-0006-4).


Figure 071-010-0006-4. Underarm firing position

 

d. Hip.  Use the hip firing position when closing with the enemy, when a heavy volume of fire in the target area is required, and when rapid movement is not necessary (figure 071-010-0006-5).


Figure 071-010-0006-5. Hip firing position

 

2.   Fire the weapon using the correct sight picture (figure 071-010-0006-6).

a. Sight alignment. Center the front sight post in the peep sight (A, figure 071-010-0006-6).

b. Focus of the eye. Place the eye directly on line with the center of the rear sight. Focus on the tip of the front sight post. The natural ability of the eye to center objects in a circle and to seek the point of greatest light (center of the peep sight) aids in providing correct sight alignment.

c. Sight picture. Center the target over the front sight post (B, figure 071-010-0006-6). If firing on a 10-meter range target, use the sight picture in C, figure 071-010-0006-6.


Figure 071-010-0006-6. Sight picture

 

3.   Fire the weapon in three-round bursts at the rate of fire appropriate for target size. Use correct trigger manipulation: Pull straight to the rear and release.

4.   Apply correct engagement technique based on target types (figure 071-010-0006-7).


Figure 071-010-0006-7. Classes of fire with respect to the weapon

 

a. Fixed fire. This type of fire is delivered against a point target when the depth and width of the beaten zone will cover the target. Only one aiming point is necessary to cover the target with fire.

b. Traversing fire. This type of fire is distributed in width by successive changes in direction. This means moving the muzzle of the weapon to the left or right to distribute fire laterally. To make minor changes in direction, shift the shoulders to the right or left to select successive aiming points throughout the width of the target area. For major changes, move the elbows and align the body to remain directly behind the gun.

c. Searching fire. This type of fire is distributed in depth by successive changes in elevation. This means moving the muzzle of the weapon up or down to distribute fire in depth. Select successive aiming points in depth throughout the target area. To make changes in elevation, move elbows closer together to lower the muzzle or farther apart to raise the muzzle.

d. Traversing and searching fire. This type of fire is distributed in width and depth by successive changes in direction and elevation. Combining traversing and searching fire provides good coverage of the target. Adjustments are made in the same manner as described for traversing and searching fire. This means moving the muzzle of the weapon to the left or right to distribute fire laterally. To make minor changes in direction, shift the shoulders to the right or left to select successive aiming points throughout the width of the target area. For major changes, move the elbows and align the body to remain directly behind the gun.

5.   Use observation of fire and adjustment of fire to place effective fire on the target.

a. Observation of fire. Observe the burst of fire by noting the strike of the rounds in the target area, the tracers in flight or, in the case of the 10-meter range, the holes made in the target.

b. Adjustment of fire. Use the adjusted aiming point method to quickly adjust fires without making a sight adjustment. If the initial burst misses the target, rapidly select a new aiming point the same distance from the center of impact of the initial burst but in the opposite direction. Fire a second burst (figure 071-010-0006-8).

6.   Use correct application of fire to engage specific targets.

a. Point target. Engage point targets with fixed fire (figure 071-010-0006-9).


Figure 071-010-0006-9. Engagement of point target

 

b. Area target. Initially, aim at the midpoint of the target area. Traverse and search to either flank, then back to the opposite flank (figure 071-010-0006-10).


Figure 071-010-0006-10. Engagement of area target

 

c. Linear target. Initially, aim at the midpoint of the target. Traverse fire to one flank and then to the other to cover the entire target (figure 071-010-0006-11).


Figure 071-010-0006-11. Linear target

 

d. Deep target. Initially, aim at the midpoint of the target unless another portion of the target is more critical or presents a greater threat. Search down to one aiming point in front of the near end and back up to one aiming point beyond the far end (figure 071-010-0006-12).


Figure 071-010-0006-12. Deep target

 

e. Linear target with depth. Initially, aim at the midpoint of the target unless another portion of the target is more critical or presents a greater threat. Traverse and search to the flank closest to your position then back to the other flank to cover the entire target (figure 071-010-0006-13).


Figure 071-010-0006-13. Linear targets with depth

 

f.  Moving target. To hit a moving target, estimate the speed of the target and the lead required to fire and hit it, fire and track the target as it moves, and adjust the lead by observing tracers and the strike of the bullets (table 071-010-0006-1 and figure 071-010-0006-14).

Evaluation Preparation: 

Setup: Evaluate this task on a live-fire range by having the soldier fire Table IV in FM 3-22.68. Evaluate the soldier's ability to use correct engagement techniques to engage specific types of targets. Provide the soldier with equipment and materials required to fire the course.

Brief Soldier: Brief soldier on range safety per installation regulations. Tell the soldier to assume the bipod-supported prone position or bipod-supported fighting position. Tell the soldier you are evaluating both his ability to adjust fire and his ability to hit the target.
