Visit Visit our website This 1955 U.S. Army film was one of a series about how to fire a machine gun. This particular film focuses on the “auxiliary aiming point“. For instructional purposes the film uses an M1919 Browning, which is a .30 caliber medium machine gun that was widely used during the 20th century, especially during World War II, the Korean War, and the Vietnam War. The demonstration utilizes the M74 weapons mount or tripod for stability, and a water jacket for cooling of the barrel. Narration: “As a machine gunner, you may find it necessary to use auxiliary aiming points in order to engage targets. An auxiliary aiming point is an object or a point used by the gunner for laying a gun on a target, when the target cannot be seen. The aiming point must be visible to the gunner regardless of his ability to see the target and must be not more than 20 mils off the line gun target. Using the heavy machine gun to obtain data using an auxiliary aiming point -- the gun is first played on the target with the correct sight setting. When the tactical situation permits, the initial lay is verified by firing. Then, without disturbing the lay of the gun, the rear sight is adjusted for deflection and elevation until the line of aim is directed at a well-defined part of the auxiliary aiming point. The center of the white “X“ on the stump. The settings of the rear sight leaf and the windage scale are carefully noted in this case. They are: deflection right one seven, elevation 1500. These site readings are then recorded. Now that sight readings for the auxiliary aiming point have been recorded, the gunner has the necessary data to enable him to re-engage this target during any condition of visibility. He is now free to engage other targets within his sector of fire. Should he wish to re-engage the first target, he would set the previously recorded data on his sights. He then aims at the stump, being sure to aim at the exact same spot the center of the white X on the stump. Although the gunner can no longer see his target, by aligning his sights on the auxiliary aiming point he has laid the gun to engage the target. Auxiliary aiming points -- these are the steps to remember: First, lay on the target with the correct sight setting to hit the target. Fire and adjust if the tactical situation permits, then without disturbing the lay of the gun, adjust the rear sight for deflection and elevation until your line of aim is on a well-defined part of the auxiliary aiming point. Record this information. When you have recorded the sight readings, you may then lay on other targets in your sector. To re-engage the first target, place the auxiliary aiming point data back on your sight. Direct your line of aim at the auxiliary aiming point, being sure to aim at the exact same spot from which the original sight readings were taken. If you have made your sight settings correctly, the gun is properly laid to engage the target.“ We encourage viewers to add comments and, especially, to provide additional information about our videos by adding a comment!
