1. What two reasons why 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.
2. What is the AN/PVS-4?
A: The AN/PVS-4 NVD is a portable, battery-operated electro-optical instrument used for observation and aimed fire of weapons at night. It amplifies reflected light, such as moonlight, starlight, and sky glow, so that the viewed scene becomes clearly visible to the operator. It can be mounted on the M16A2/A3/A4 rifle and M4/M4 MWS. Mounting brackets are provided for each type of weapon. REF: FM 3-22.9, 8-95
3. What are the four methods used to destroy a weapon?
A: Mechanical, Burning, Demolition, Disposal REF: FM 3-22.9, 3-28, Table 3-2
4. What are the eight cycles of function for the M4 carbine?
A: Feeding, Chambering, Locking, Firing, Unlocking, Extracting, Ejecting, Cocking
5. What are the two primary components of a marksmanship training strategy?
A: Initial training and sustainment training REF: FM 3-22.9, 1-4
6. What are two actions a firer can use to clear a stoppage?
A: Immediate action, Remedial Action REF: FM 3-22.9, 3-1
7. What is the difference between the M4 and M4A1 Carbine
A: M4A1 is fully automatic REF: FM 3-22.9, 2-2
10. External ballistics deals with factors affecting the flight path of the bullet between the weapon's muzzle and the target, name 4 of these factors?
A: Gravity, Muzzle Velocity, Air Resistance (drag), Altitude or air density, temperature, Trajectory, Wind, angles REF: FM 3-22.9, 5-100
11. What is the correct setting for the elevation knob on the backup iron sight in order to fire field fire?
A: 300 meter line (8-14)
12. In reference to external ballistics, a 5000 ft rise in elevation will move the bullet strike how far?
A: ½ to 1 MOA (5-98)
13. What is the cyclic rate of fire for the M4?
A: 700-900 rounds per minute (table 2-1)
14. Should the adjusted point of aim be higher or lower for a 150m target?
A: Lower (5-70)
15. What is the rifling twist ratio in the M4 carbine?
A: 1:7; 1 twist every 7 inches (5-87)
17. The BUIS provides a sighting capability for other sighting components without requiring live fire. What is the effective distance when zeroing other sighting components with the BUIS.
A: Approximately 20 meters. Ref: 3-22.9
20. What does LOMAH stand for, and how do you achieve a 300 meter zero using the LOMAH system?
A: Location of Misses and Hits. the Soldier shoots six rounds at the 175-meter/200-yard target while aiming at the target's center of mass. The outcome is evaluated using the following guidelines: If the shot group falls within the 11-inch circle on the LOMAH monitor, the Soldier continues the programmed scenario, which is identical to the downrange feedback scenario without LOMAH. If the Soldier shoots a shot group that is 11 inches or smaller but is clearly not zeroed, the instructor/trainer assists the Soldier in making sight adjustments based upon the data provided on the LOMAH monitor. If the shot group is not tight (greater than 11 inches), the Soldier should be removed from the firing line and given remedial training on the four fundamentals of marksmanship. Ref 3-22.9, Chg 1, 10 Feb 11, Page 5-19, Para 5-48
