Para 3-28 Who can authorize the destruction of weapons? | Only the Commander |
Para 3-28 What are the Authorized Methods of Destruction of Weapons and how are they performed? | 1. Mechanical; Use an axe, pick, mattock, sledgehammer, crowbar, or other heavy implement 2. Burning; Use gasoline, oil, incendiary grenades, other flammables, or a welding/cutting torch 3. Demolition; Use suitable explosives, ammunition or, as a last resort, hand grenades 4. Disposal; Bury essential parts, dump them in streams or marshes, or scatter them so widely that recovering them would be impossible |
Para 3-30 What is priority order in which weapon parts should be destroyed? | (1) Bolt carrier group. (2) Upper receiver group. (3) Lower receiver group |
Para 4-0 What is an Infantryman’s basic battlefield tool? | An Infantryman’s basic battlefield tool is his weapon |
Para 4-1 How do you properly clear an M16-/M4-series weapon? | (1) Point the muzzle in a designated safe direction or in a clearing barrel. (2) Attempt to place the selector lever on SAFE. If the selector lever cannot be placed on SAFE because the weapon is not cocked, proceed to Step 3. (3) Remove the magazine (4) Lock the bolt open. (5) Visually inspect the receiver and chamber to ensure that these areas contain no ammunition. (6) Allow the bolt to move forward by pressing the upper portion of the bolt catch. (7) Place the selector lever on SEMI. (8) Squeeze the trigger. (9) Pull the charging handle fully rearward and release it, allowing the bolt to return to the full forward position. (10) Place the selector lever on SAFE. (11) Close the ejection port cover |
Para 4-2 What are the eight cycles of functioning for the M16/M4 Series weapon? | 1. Feeding. 2. Chambering. 3. Locking. 4. Firing. 5. Unlocking. 6. Extracting. 7. Ejecting. 8. Cocking. |
Para 4-12 What are three modes of fire for the M16/M4 series weapons? | 1. Semiautomatic. 2. Automatic. 3. Burst |
Para 4-32 What are the Four Fundamentals of Firing? | 1. Steady Position 2. Aiming 3. Breathing Control 4. Trigger Squeeze |
Para 4-34 How can the Firer tell if they have a Good Steady Position? | If he can hold the front sightpost steady through the fall of the hammer |
Para 4-34 What are the Elements that make up a Good Steady Position? | 1. Nonfiring hand grip. 2. Rifle's buttstock position. 3. Firing hand grip. 4. Firing elbow placement. 5. Nonfiring-side elbow placement. 6. Cheek-to-stock weld. 7. Support and muscle relaxation. 8. Natural point of aim |
Para 4-42 What should be used to steady the position and support the weapon? | Artificial support (for example, sandbags, logs, or stumps) |
Para 4-42 What should be used if No Artificial support is available? | The Bones of the upper body and Not the Muscles, using the muscles can lead to fatigue which will cause the weapon to move more |
Para 4-52 What are the Two breath control techniques practiced during dry-fire? | 1. Breath control for engaging single targets. 2. Breath control for engaging short-exposure targets |
Para 4-57 What are the Two reasons Trigger squeeze is important? | 1. Any sudden movement of the finger on the trigger can disturb the lay of the rifle and cause the shot to miss the target. 2. The precise instant of firing should be a surprise to the Soldier. If a Soldier knows the exact instant that the rifle will fire, the Soldier will naturally compensate for the weapon's noise and recoil, causing him to miss the target. Soldiers usually tense their shoulders when expecting the rifle to fire; it is difficult to detect since the Soldier does not realize that he is flinching |
