List of signal grenades of the United Kingdom

Last updated

The British Army used several signal grenades from their introduction in the 20th century.

Contents

Usage

The grenades were used to communicate information through pre-arranged combinations of coloured smoke and lights. Generally smoke was for daytime use and lights at night but some light producing grenades were suitable for daytime use. [1]

List

Rifle grenades

Used with rifle discharger clipped to front of rifle and propelled by blank cartridge with 30 grains of ballistite. [2] Signal grenades were fired holding the rifle at 70 degrees, the butt on the ground and the rifle trigger uppermost. [3] [lower-alpha 1]

Rodded grenade type where a 15-inch long rod at base of grenade is inserted into the rifle [lower-alpha 2] and fired from barrel with a blank cartridge of 43 grains cordite. [2] This was older method of firing grenades.

Hand grenades

Notes

  1. A gas port on the discharger was used to adjust range between 80 and 200 yd (73 and 183 m) when firing other types of grenades but signal grenades were used with port closed [4]
  2. The rifle was given reinforcement in the form of wire binding round the fore end of the gun over 5 inches [2]

A grenade launcher is a weapon that fires a specially designed, large-caliber projectile, often with an explosive, smoke, or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces.

<span class="mw-page-title-main">M203 grenade launcher</span> Grenade launcher

The M203 is a single-shot 40 mm under-barrel grenade launcher designed to attach to a rifle. It uses the same rounds as the older stand-alone M79 break-action grenade launcher, which utilizes the high-low propulsion system to keep recoil forces low. While compatible with many weapons, the M203 was originally designed and produced by the United States military for the M16 rifle and its carbine variant, the M4. The launcher can also be mounted onto a C7, a Canadian version of the M16 rifle; this requires the prior removal of the bottom handguard.

A rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade were thrown by hand.

<span class="mw-page-title-main">Blank (cartridge)</span> Firearms filler device that produces an explosion but does not fire a projectile

A blank is a firearm cartridge that, when fired, does not shoot a projectile like a bullet or pellet, but generates a muzzle flash and an explosive sound like a normal gunshot would. Firearms may need to be modified to allow a blank to cycle the action, and the shooter experiences less recoil with a blank than with a live round. Blanks are often used in prop guns for shooting simulations that have no need for ballistic results, but still demand light and sound effects, such as in historical reenactments, special effects for theatre, movie and television productions, combat training, for signaling, and cowboy mounted shooting. Specialised blank cartridges are also used for their propellant force in fields as varied as construction, shooting sports, and fishing and general recreation.

The .30-06 Springfield cartridge, 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. In the cartridge's name, ".30" refers to the nominal caliber of the bullet in inches; "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03 Springfield, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. The cartridge remains a very popular sporting round, with ammunition produced by all major manufacturers.

<span class="mw-page-title-main">United States 40 mm grenades</span> Ammunition variants in military use

The United States Armed Forces has created a plethora of different types of 40 mm grenades in both the low-velocity 40×46 mm and high-velocity 40×53 mm calibers which uses what it calls a high-low propulsion system which keeps recoil forces within the boundaries of an infantry weapon. Presented on this page is a basic overview.

The Sturmpistole ("assault-pistol") was an attempt by Germany during World War II to create a multi-purpose weapon which could be used by any infantryman. It consisted of a modified flare gun (Leuchtpistole) which could fire a variety of grenades, including a 600 g shaped charge Panzerwurfkörper 42 which could penetrate 80 mm (3.1 in) of rolled homogeneous armor. The idea was not pursued wholeheartedly, and took second stage to the then current anti-tank rifles and later weapon developments, such as the Panzerfaust recoilless and Panzerschreck rocket.

The M7 grenade launcher, formally rifle grenade launcher, M7, was a 22 mm rifle grenade launcher attachment for the M1 Garand rifle that saw widespread use throughout World War II and the Korean War. The M7 was a tube-shaped device, with one end slotting over the muzzle of the rifle and attaching to the bayonet mount, and the other end holding the grenade in place. Blank cartridges were loaded into the rifle prior to firing. When fired, the expanding gases generated by the cartridges propelled the grenade forward with considerable force. The M7 could fire grenades up to 200 metres, compared with the maximum of 30 metres achieved by a hand-thrown grenade.
