Head Position Ebook
It should be explained to a new shooter that it is important to place his spotting telescope in a favorable location (Figure 18). This is true of all the shooting positions, but it is most critical when shooting the prone positions. The scope should be placed so that only a slight movement of the head is necessary to bring the eye to the lens. If the shooter must raise or move his body to see through the scope, he may change the established position for his next shot. This shifting can change the natural point of aim or the head position. Unless the change of position is redressed it can move the point of impact.
Body-Rifle Weight Supported by Bone Structure As a result of this back bend and body twist, the weight of the rifle and upper torso falls upon the bones of the lower spinal column. Hip and leg bones transmit this weight ultimately to the feet. Thus the weight of the rifle is almostly completely supported by bones. The only work required of body muscles is to keep the body in a standing posture and prevent it from swaying from its point of balance.
When the firer is firing unassisted, changes in his head position and or stock weld will be necessary, especially when using weapon-target alignment techniques. His head is positioned high so that he is aligning his weapon on the target and looking just over the iron sights. His cheek should remain in contact with the stock. Repeated dry-fire practice, followed by live-fire training, is necessary to learn and refine these modifications and still achieve the steadiest position.
Cheek pressure is also critical in affecting the angle of jump. If the cheek is moved forward or back on the stock, or if the cfieek pressure is increased or decreased on the stock, there will be a noticeable change in the point of impact. This can occur in any position, and it occurs even though each shot may break with the sights in perfect alignment on the target. The shooter should take care to apply the exact same check pressure to the exact same point on the stock throughout a series of shots. Most good shooters rest the head naturally against the stock. They do not attempt to increase or decrease this natural pressure by use of the muscles. Experience will teach the shooter to sense unintentional changes in head position or cheek pressure. The shooter should attempt to hold the rifle in exactly the same way each time he fires during a string.
All the movements of the eyeball, as well as the holding of its fixed position at moments when the glance is fixed on some object, are effected by the work of three pairs of eye muscles. During the time when the eyes are at work, including the times when the eye is aiming, these muscles are in a state of indiscernible, slight vibration or quivering. For example, when aiming a pistol and the shooter turns his head down and to the right, the eyeball turns respectively upward and inward, it is held in the least desirable position one that requires the combined, intensified work of all three groups of muscles (Figure A2-8). When the eye muscles become fatigued, the involuntary quivering of the eyeball increases considerably and this lessens the accuracy of aiming. Therefore, the shooter must devote major attention to the position of his head when firing. He must select that firing stance in which the head position is the most natural one, with the least amount of tilt, so that the shooter...
The palm rest is used to bring the rifle stock up to the level of the face. Some shooters are able to accomplish this without the use of a palm rest. They simply support the rifle with the left hand. Others use only a small block of wood (Figure 51). The important point is that the correct position of the body is assumed and the rifle is fitted to the body, not the body to the rifle I The palm rest is positioned on the heel of the hand, and the left wrist is comfortable. The beginning shooter will find that correctly adjusting the palm rest and butt hook may prove to be a oewildering task. Part of this difficulty arises because he does not yet know his position. He has not used the standing position enough to be able to sense minor changes in body posture. Consequently, he will not know whether he has assumed the same position each time he fires. As a result, from time to time it will appear that the rifle is not adjusted.
Wearing the field protective mask affects the aiming process and the ability to locate targets. The bulk of the mask may require an adjustment to stock weld, eye relief, head position, and placement of the buttstock in the shoulder. 9 (3) Head Position. The mask's shape and bulk can make sight alignment difficult to achieve.
Improvement of recovery must be approached from two angles Reestablish a hold in the center of the aiming area, and realignment of the front and rear sights in perfect relationship. Practice and re-practice assuming a proper position that furnishes the shooter with a natural hold that points the shooting arm and weapon at the center of the aiming area. Get a proper grip and head position that
A head position which will allow for the most efficient use of the shooter's eyes throughout the sighting and aiming process. a. When assuming the firing stance, the head must be held as level as possible, so that the shooter can see the target directly in line with the arm and sights. It is necessary to take all steps to eliminate the tilting of the head to the right or left or an excessive tilting forward. It is not necessary to look sideways or to look at the sights from beneath the eyebrows. The head should not be pushed forward closer to the rear sight neither should the head be tilted back excessively. This causes undue tension upon the neck muscles and, as a consequence, a slight movement of the head develops from fatigue. This may hinder the maintenance of perfect sight alignment. k. The group of muscles which do not directly participate in maintaining the shooter's body in the vertical position or holding the pistol aimed at the target is the muscles of the left arm and...
When the firer is firing unassisted, changes in his head position stock weld will be necessary, especial when using weapon-target alignment techniques. When using rifle-mounted night vision devices, head position stock weld must be changed to bring the firing eye in line with the device. Also, such mounted devices alter the rifle's weight and center of gravity, forcing a shift in placement of the support (non firing arm or sandbags). Repeated dry-fire practice, followed by live-fire training, is necessary to learn and refine these modifications and still achieve the most steady position.
Unlike the bipod, the tripod does not allow the machine gun to be canted. This requires the gunner to position his head behind the stock to use the sight. Skilled gunners who make adjustments to the T&E quickly can confirm their sight picture and then look over the sights to observe the strike of the round while firing. This not only provides relief for the neck muscles but aids in making adjustments.
The bulk of overgarments may require adjustments to the position for stability and comfort. A consistent stock weld is difficult to maintain because of the shape of the protective masks. The gunner has to hold his head in an awkward position to see through the sight. If necessary, he may cant the weapon to overcome this situation. This procedure relieves the neck muscles and places the eye on line with the center of the rear sight.
