The trigger for the AT4 is a red button on the right side of the tube. To fire the launcher, you must apply pressure straight forward with the thumb of your right hand in a steady, smooth movement. Proper trigger manipulation (fig. 14-37) can be developed by dry-fire practice with an expended AT4 or AT4 training devices.

FIRING POSITIONS

The AT4 is fired from the right shoulder only. It may be fired from the standing, kneeling, sitting, or prone position. The exact position may vary slightly to allow for the configuration of an individual's body. Any of these positions are suitable for stationary targets. In general, the most suitable positions for engaging moving targets are standing and kneeling. Situation, terrain, and gunner preference should govern the selection of the best position. Whenever possible, support should be used to stabilize the gunner's aim.

Standing Position

The standing position (fig. 14-38) is similar to that of firing a rifle. Face the target, execute a half-right face, spread your feet a comfortable distance apart, and place the launcher on your right shoulder; your body should be well-balanced with your hips level. Your left hand

should be directly under the front of the launcher, grasping the carrying sling. Your left elbow should be placed against your body for stability. Grasp the firing mechanism with your right hand and keep your right elbow placed tightly against the body.
