State the magazine capacity, maximum range, maximum effective range, employment, rates of fire, and types of ammunition of the following weapons:
A. M9 Service Pistol
B. M4 Rifle
**Common Core*
A. M9 Service Pistol
Magazine Capacity: 15 rounds (9mm NATO)
Maximum Range: Approximately 50 meters (164 feet)
Maximum Effective Range: Approximately 50 meters (164 feet)
Employment: The M9 is used as a sidearm for military personnel, especially in close-quarters situations or when a primary weapon (like a rifle) is not ideal or unavailable. It can also be employed as a secondary weapon during operations requiring mobility or for self-defense.
Rates of Fire:
Types of Ammunition: 9mm NATO FMJ (Full Metal Jacket)
B. M4 Rifle
Magazine Capacity: 30 rounds (5.56mm NATO)
Maximum Range: Approximately 3,600 meters (3.6 km or 11,811 feet)
Maximum Effective Range: Approximately 500 to 600 meters (1,640 to 1,970 feet)
Employment: It is suitable for both close-quarters battle and mid-range engagements.
Rates of Fire:
Semi-Automatic Mode: One round per trigger pull.
Fully Automatic Mode: Approximately 700-900 rounds per minute (depending on the version of the M4).
Burst Mode: In some M4 models, a burst mode fires a 3-round burst with each trigger pull.
Types of Ammunition:
Standard Ammunition:
5.56mm NATO FMJ (Full Metal Jacket)
**Common Core*
Discuss loading/unloading procedures of the following weapons
A. M9 service pistol
B. M4 rifle
**Common Core*
**Common Core*
Describe and discuss the following types of grenades
A. Fragmentation
B. Illuminating
C. Chemical
D. Incendiary
E. Smoke
F. Practice/Training
G. Concussion
**Common Core*
A. Fragmentation grenades are designed to explode and release numerous sharp, high-velocity fragments in all directions, causing damage to both personnel and equipment within a certain radius.
B. Illuminating grenades are designed to emit a bright light when they explode.
C. Chemical grenades release toxic chemicals or gases when detonated. These chemicals may cause harmful effects such as suffocation, nausea, blindness, or even death. The specific chemical agents used depend on the grenade type, but they can include nerve agents, blister agents, or choking agents.
D. Incendiary grenades contain a flammable substance (e.g., white phosphorus, thermite) that ignites upon detonation, creating intense heat and flames. These grenades are designed to cause fires or to burn through materials, such as vehicles, equipment, or structures.
E. Smoke grenades produce a large volume of smoke when activated. They typically release colored smoke, such as white, green, or red, which can be used for signaling or to obscure vision.
F. Practice or training grenades are non-lethal replicas of live grenades. These grenades are designed for training purposes, allowing soldiers to familiarize themselves with the mechanics of grenade use without the danger of actual detonation.
G. Concussion grenades, also known as flash-bang grenades or stun grenades, are designed to create a loud noise and a flash of light to disorient and incapacitate enemy personnel temporarily. These grenades rely on shockwaves, loud explosions, and bright flashes to temporarily blind and deafen enemies, rather than causing physical injury.
**Common Core*
Discuss hand grenade safety procedures
**Common Core*
- Treat every grenade as live and handle with care.
- Do not remove the pin until ready to throw the grenade.
- Keep the spoon secure until the grenade is thrown.
- Always check your surroundings before throwing the grenade to avoid unintended injuries.
- Seek cover immediately after throwing the grenade to avoid injury from the blast or shrapnel.
- If a grenade fails to detonate, do not approach it, and report it as a dud.
**Common Core*
Discuss the characteristics and purpose of the Claymore mine
**Common Core*
fragmentation pattern and remote detonation
**Common Core*
For the 7.62mm M240B machine gun
Describe the characteristics of the machine gun
**Common Core*
Medium - 240B
Heavy - M2
Designed for sustained fire. It is capable of firing multiple rounds in rapid succession with a single pull of the trigger. Machine guns are primarily used in military applications and are designed to provide suppression, firepower, and area denial against enemy forces.
