Stokes mortarThe Stokes mortar was a British trench mortar designed by Sir Wilfred Stokes KBE that was issued to the British and U.S. armies, as well as the Portuguese Expeditionary Corps, during the latter half of the First World War. The 3-inch trench mortar is a smooth-bore, muzzle-loading weapon for high angles of fire. Although it is called a 3-inch mortar, its bore is actually 3.2 inches or 81 mm. The Stokes mortar was a simple weapon, consisting of a smoothbore metal tube fixed to a base plate (to absorb recoil) with a lightweight bipod mount.
Bombard (weapon)The bombard is a type of cannon or mortar which was used throughout the Middle Ages and the early modern period. Bombards were mainly large calibre, muzzle-loading artillery pieces used during sieges to shoot round stone projectiles at the walls of enemy fortifications, enabling troops to break in. Most bombards were made of iron and used gunpowder to launch the projectiles. There are many examples of bombards, including Mons Meg, the Dardanelles Gun, and the handheld bombard.
Grenade launcherA 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. Grenade launchers are produced in the form of standalone weapons (either single-shot or repeating) or as attachments mounted to a parent firearm, usually a rifle.
Fire supportFire support is a military term used to describe weapons fire used to support friendly forces by engaging, suppressing, or destroying enemy forces, facilities, or materiel in combat. It is often provided through indirect fire, though the term may also be used for some forms of supporting direct fire. The United States Department of Defense defines fire support as "fires that directly support land, maritime, amphibious, and special operations forces to engage enemy forces, combat formations, and facilities in pursuit of tactical and operational objectives.
Infantry support gunInfantry support guns or battalion guns are artillery weapons designed and used to increase the firepower of the infantry units they are intrinsic to, offering immediate tactical response to the needs of the unit's commanding officer. They typically have short, low-velocity barrels, and light construction carriages, allowing them to be more easily manoeuvered on the battlefield. They are generally used for direct fire, rather than the indirect fire of other types of artillery.
Gun-howitzerGun-howitzer (also referred to as gun howitzer) is a type of artillery weapon that is intended to fulfill the roles of both an ordinary cannon or field gun, and of a howitzer. It is thus able to convey both direct and indirect fire. Modern gun-howitzers are usually identified just as howitzers. To be able to serve as a howitzer, gun-howitzers are typically built to achieve at least 60° to 70° of elevation. For effective direct fire, the gun-howitzers typically employ a fairly long gun barrel, usually not shorter than 30 calibres.
Smoke screenA smoke screen is smoke released to mask the movement or location of military units such as infantry, tanks, aircraft, or ships. Smoke screens are commonly deployed either by a canister (such as a grenade) or generated by a vehicle (such as a tank or a warship). Whereas smoke screens were originally used to hide movement from enemies' line of sight, modern technology means that they are now also available in new forms; they can screen in the infrared as well as visible spectrum of light to prevent detection by infrared sensors or viewers, and they are also available for vehicles in a super-dense form used to block laser beams of enemy laser designators or rangefinders.
No man's landNo man's land is waste or unowned land or an uninhabited or desolate area that may be under dispute between parties who leave it unoccupied out of fear or uncertainty. The term was originally used to define a contested territory or a dumping ground for refuse between fiefdoms. In modern times, it is commonly associated with World War I to describe the area of land between two enemy trench systems, not controlled by either side. The term is also used metaphorically, to refer to an ambiguous, anomalous, or indefinite area, in regard to an application, situation, or jurisdiction.
