What is the only illuminating grenade currently available according to the SCH?
MK1
Its main use to to illuminate terrain in night operations. It provides about 55,000 candlepower for a period of 25 seconds. The MK1 grenade may also be used as an incendiary grenade to start fires in dry grass, leaves, or brush.
the most commonly used chemical grenade is the?
ABC-M25A2, CS riot control hand grenade
The grenades are filled with chloracetophenone, a type of tear gas that causes irritation and watering of the eyes, resulting in temporary, partial, or total blindness. The body of the grenade is spherical and is made of plastic. It contains about 3.5 ounces of a mixture of CS and weighs about 7.5 ounces.
This grenade does not have a safety lever as other grenades do. To prevent the grenade from activating after the safety pin is removed, you must keep pressure on the top of the arming sleeve with the thumb of your throwing hand.
The radius of the burst is approximately 6 meters, but fragments of the plastic body occasionally fly as far as 27 meters. Effective portions of the agent may be carried as far as 75 to 100 meters downwind. Personnel using these grenades should wear protective gas masks.
What is the COC?
COMBAT OPERATIONS CENTER
The COC is established to provide the battalion commander centralized command and control facilities for all combat tactical and operational operations conducted under his or her command. It is the focal point for the battalion and the terminating point for all tactical and nontactical radio nets.
The primary purpose of the COC is to monitor and record the tactical and nontactical operations of the battalion continually. The specific composition and functions of the COC will vary with the desires of the individual commander
A defined area of land in which responsibility is specifically assigned to the commander of the area for the development and maintenance of installations, the control of movement, and the conduct of tactical operations involving troops under the commander’s control, along with parallel authority to exercise these functions.
AREA OF RESPONSIBILITY (AOR)
How is the number 3 spoken over the radio according to the seabee combact handbooks?
THUH-REE
What is the range of the M67 fragmentation grenade?
This range depends entirely on the throwing ability of each individual. As a well-trained Seabee, you should be able to throw a grenade, such as the M67 fragmentation grenade, about 35 to 40 meters.
What is your first step in throwing an hand grenade?
First, observe the target and establish the distance between your throwing position and the target area
What is an antenna farm?
The antenna farm or communication site is the primary location of various antennas and communication equipment needed to establish communication in the field.
An air or ground route of attacking forces of a given size leading to its objective or key terrain in its path.
AVENUE OF APPROACH
What are the three types of combat signals?
1 - whistle
2 - special (rifle shots)
3 - arm and hand
what is currently the only mine authorized for use by the Seabees, is used only as an electrically controlled, one-shot weapon?
The Ml8A1 Claymore mine
It is used for support of other weapons used in the final protective fire of the unit. It is a directional, fixedfragmentation mine and is designed primarily for use against massed infantry attacks.
The mine weighs about 3 1/2 pounds and is 8 1/2 inches long, 1 3/8 inches wide, and 3 1/4 inches high. The outer surface is a curved rectangular, olive drab, molded plastic case. The front portion of the case has a fragmentation face containing steel spheres embedded in a plastic matrix (enclosure). The back portion of the case contains 1 1/2 pounds of Composition C4 (composite explosive).
When detonated, the Ml8A1 mine projects steel fragments over a 60-degree fan-shaped pattern approximately 6 feet high and 50 meters wide at a range of 50 meters. These fragments are moderately effective up to a range of approximately 100 meters and can travel up to 250 meters. The optimum effective range–the range at which the most desirable balance is achieved between lethality and area coverage–is 50 meters.
what is the firing device issued with each Ml8A1 mine?
M57
The device is a hand-held pulse generator. A squeeze of the handle produces a double 3-volt electrical pulse of sufficient energy to fire the electric blasting cap through the 100 feet of firing wire issued with the mine. On one end of the firing device is a rubber connecting plug with a dust cover.
What is the required timing for an immediate message?
30 minutes - 1 hour
FLASH: Not fixed. Handle as fast as humanly possible; objective is less than 10 minutes.
IMMEDIATE: 30 minutes-1 hour.
PRIORITY: 1-3 hours.

what is the most commonly used trip flare?
M49 trip flare
The M49 trip flare resembles a hand grenade in size and shape, except that it is provided with a bracket for attachment to a tree or post and a trigger mechanism for firing. The flare burns with a yellowish light and illuminates an area radius of approximately 300 meters. The trip fuze M12 resembles the hand grenade fuzes for cylindrical hand grenades, but it has no body tube or delay charge.
