A hand grenade is a hand-held bomb, made to be thrown by a soldier. The word "grenade" has a Spanish origin in the word granada (" pomegranate"), in reference to the general size of early grenades, and because its content of shrapnel pellets reminded them of the seeds in a pomegranate. Grenadiers were originally a class of soldier specialized in throwing grenades. Some grenades are designed to be fired by a grenade launcher.
Some grenades are cylindrical and are designed to be fired from riot guns designed for the purpose.
Grenades come in different sizes and shapes, for different purposes, but all have two things in common. First, they are hollow so they can be filled with the explosive or chemical filler. Second, they contain a threaded hole into which a fuse can be screwed or inserted.
A grenade is essentially a small bomb, and works very much like a simple firecracker. A firecracker is made up of a paper body filled with gunpowder and has a small fuse. Once lit, the fuse burns down to the powder and blows the paper body apart. A grenade differs mainly in that the fuse is lit by an internal mechanical device rather than an external flame.
Hand grenades share the following three common characteristics:
Hand grenades have the following main parts:
A classic hand grenade has a handle and a removable safety pin that prevents the handle from coming off. After removing the pin and subsequently releasing the handle, the grenade will detonate in approximately four secondThis article is about the unit of time. See second (disambiguation) for other uses The second (symbol s is a unit for time, and one of seven SI base units. It is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transis.
When using a grenade, the objective is to have the grenade land with too little time for the enemy to throw it back.
One grasps the grenade, including the handle, in the strong handAmbidexterity is the ability of being equally adept with each hand (or, to a limited degree, feet). See laterality. While ambidexterity can be learned, most people still gravitate towards performing certain types of tasks with a specific hand. The degree. Next one estimates the time of flight to the enemy and subtracts four from it. Then one pulls the pin out of the grenade, releases the handle, waits the time not needed for flight and throws the grenade at the intended target.
Note: Modern USA and NATOThe North Atlantic Treaty Organisation NATO , sometimes called North Atlantic Alliance Atlantic Alliance or the Western Alliance is an international organization for defense collaboration established in 1949, in support of the North Atlantic Treaty signed soldiers are trained not to "burn off" (also called "cook off") grenades in this way, due to the danger of it explodingAn explosion is a sudden increase in volume and release of energy in a violent manner, usually with the generation of high temperature and the release of gases. An explosion causes pressure waves in the local medium in which it occurs. Explosions are cate in hand if the soldier is distracted or shot.
One of the classic mistakes is to grasp the grenade in the weak hand, pull the pin, and then throw the pin. (This mistake is a staple of humorous cartoons involving war.)
Another classic mistake is to fail to grasp the handle, and then pull the pin. In this case, the grenade might explode while one is calculating times.
A basic safety precaution is to always throw a grenade from cover. Therefore, if anything goes wrong, it can be thrown quickly out of the cover.
When a grenade is out of control, yell "grenade." When a grenade is dropped into a enclosed space like a tunnel, the dropper should yell "Fire in the hole!" to alert his comrades that an explosive is about to detonate.
Grenades are often used in the field to construct booby-traps. The basic concept is to use some action of the intended target (such as opening a door, or starting an auto) to trigger the grenade. These grenade-based booby-traps are simple to construct in the field using readily available material. However, they contribute to the problem of unexploded ordnance.
