XM307
The XM307 Advanced Crew Served Weapon (ACSW) was a developmental 25 mm belt-fed automatic grenade launcher with programmable airburst capability. It is the result of the ''OCSW'' or ''Objective Crew Served Weapon'' project. It is lightweight and designed to be two-man portable, as well as vehicle mounted. The XM307 can kill or suppress enemy combatants out to 2,000 meters (2,187 yd), and destroy lightly armored vehicles, watercraft, and helicopters at 1,000 meters (1,094 yd). The project was canceled in 2007. Overview The system was under development by General Dynamics Armament and Technical Products for the U.S. Army Tank-Automotive and Armaments Command (TACOM). As a part of the ''Small Arms Master Plan'' (SAMP) program, it is intended to either replace or supplement the Mk19 automatic grenade launcher and the M2 heavy machine gun.

XM312
The XM312 is a heavy machine gun derived from the XM307 25 mm autocannon and chambered for the .50 BMG cartridge. It was designed in response to a request by the Military of the United States, U.S. military for a replacement for the aging M2 Browning heavy machine gun, and as a complement to the heavier XM307 Advanced Crew Served Weapon grenade launcher. It is capable of being converted quickly into an XM307 with a small number of parts and a few minutes of work at the unit level (and vice versa from the XM307). The Fiscal Year 2008 Appropriations bill awarded $10 million to General Dynamics for the XM307 and XM312. In May 2008 the United States Army, U.S. Army had awarded General Dynamics Armament and Technical Products (GDATP) a $9 million contract to develop a lightweight .50-caliber machine gun called the XM806 to supplement the Browning M2.

OCSW
The OCSW (''Objective Crew Served Weapon'') was a U.S. Military arms program started in the 1980s that led to a hybrid smaller prototype automatic autocannon developed by General Dynamics Armament Systems. It led to the XM312 and XM307 designs. As a part of the SAMP (''Small Arms Master Plan'') program, it had the same laser targeting system as the XM29 OICW, but was intended to supplement the 40 mm Mk 19 grenade launcher and the .50 M2 Browning machine gun. It could fire armor-piercing or explosive 25 mm grenades at a cyclic rate of 260 rounds per minute, and had an effective range up to 2 kilometres. It underwent combat trials before being cancelled.

Air Burst
An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion (as well as any shell fragments) is distributed more evenly over a wider area; however, the peak energy is lower at ground zero. History Air burst artillery has a long history. The shrapnel shell was invented by Henry Shrapnel of the British Army in about 1780 to increase the effectiveness of canister shot. It was widely used by the time of the War of 1812 and stayed in use until it was superseded during the First World War. Modern shells, though sometimes called "shrapnel shells", actually produce fragments and splinters, not shrapnel. Air bursts were used in the First World War to shower enemy positions and men with shrapnel balls to kill the largest possible number with a sing ...

Airburst Round
An airburst round is a type of tactical anti-personnel explosive ammunition, typically a shell or grenade, that detonates in midair, causing air burst effect fragment damage to an enemy. This makes it easier to hit enemy soldiers behind a wall, in a defensive fighting position, or in a confined space or room. It is used on many guns, from artillery to the hand-held XM25 Individual Airburst Weapon System (derived from the XM29 OICW). Unlike traditional grenades, such as the 40 mm grenade, smart grenades can be electronically programmed to explode after traveling a certain distance. A fire control computer or some other electronic sighting system is used to quickly program the electronic fuse with any distance, as conditions dictate. Orbital ATK developed 30x173mm Mk310 PABM-T airburst rounds for Mk44 Bushmaster II. Terminology It is also called an airburst shell, air burst grenade, programmable ammunition, 3P ammunition or smart grenade. List of airburst round platfo ...

Future Combat Systems
Future Combat Systems (FCS) was the United States Army's principal modernization program from 2003 to early 2009. Formally launched in 2003, FCS was envisioned to create new brigades equipped with new manned and unmanned vehicles linked by an unprecedented fast and flexible battlefield network. The U.S. Army claimed it was their "most ambitious and far-reaching modernization" program since World War II. Between 1995 and 2009, $32 billion was expended on programs such as this, with little to show for it. In April and May 2009, Pentagon and army officials announced that the FCS vehicle-development effort would be canceled. The rest of the FCS effort would be swept into a new, pan-army program called the Army Brigade Combat Team Modernization Program. Development history The early joint DARPA–Army Future Combat Systems program to replace the M1 Abrams main battle tank and Bradley Fighting Vehicles envisioned robotic vehicles weighing under six tons each and controlled remotely ...

Remotely Operated Vehicle
A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the air. ROVs are unoccupied, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform or on proximate land. They are common in deepwater industries such as offshore hydrocarbon extraction. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimize ...

Collateral Damage
Collateral damage is any death, injury, or other damage inflicted that is an incidental result of an activity. Originally coined by military operations, it is now also used in non-military contexts. Since the development of precision guided munitions in the 1970s, military forces often claim to have gone to great lengths to minimize collateral damage. Critics of use of the term "collateral damage" see it as a euphemism that dehumanizes non-combatants killed or injured during combat, used to reduce the perceived culpability of military leadership in failing to prevent non-combatant casualties. Collateral damage does not include civilian casualties caused by military operations that are intended to terrorize or kill enemy civilians (e.g., the bombing of Chongqing during World War II). Etymology The word "collateral" comes from medieval Latin word ''collateralis'', from ''col-'', "together with" + ''lateralis'' (from ''latus'', ''later-'', "side" ) and is otherwise mainly use ...
