Combat Arms Training and Maintenance (CATM), or simply Combat Arms are United States Air Force Security Forces personnel who train base populace on the use of small arms, oversee, maintain and repair all small arms in the U.S. Air Force inventory.
 AFSC 3P0X1B, SEI 312 (TSgt and above) are Security Forces personnel who completed the 7 week Combat Arms Apprentice Course (Lackland AFB) and conduct marksmanship training to prepare all Air Force personnel for home station and deployment operations.
 Combat Arms specialists lead, manage, supervise and implement small arms weapons training programs.
 Their duties include operating firing ranges and associated facilities, enforcing range safety, inspecting/repairing weaponry, performing preventative maintenance, developing/utilizing training aides and determining training/maintenance resource requirements.
 Combat Arms personnel also provide training in safeguarding weapons, ammunition and equipment; instructing small arms weapons qualification training and providing guidance on weapons placement to SF and other ground defense force commanders.
 Combat Arms Instructors are the Air Forces small arms weapons Subject Matter Experts (SME).
Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to a higher internal pressure than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
 This is done typically to produce rounds with a higher muzzle velocity and stopping power, such as ammunition used for defensive purposes.
 Because of this, +P ammunition is typically found in handgun calibers which might be used for defensive purposes.
An Yue Jiang (Chinese: 安岳江, Hanyu Pinyin: "Ān Yuè Jiāng") is a People's Republic of China container vessel operated by the state-run shipping firm COSCO.
 In 2008, it became notable because of controversy surrounding a cargo of arms and ammunition destined for Zimbabwe.
 The cargo reportedly includes some 3 million rounds of small arms ammunition, 1,500 rocket propelled grenades, and 2,500 mortar rounds.
 The vessel originally planned to dock at the South African port of Durban and unload its cargo for shipment to landlocked Zimbabwe.
 However, there were widespread protests by persons concerned that the arms would be used by Robert Mugabe's regime in suppressing political opposition in the wake of disputed elections.
 Dock workers stated that they would not unload the cargo, and others threatened to stop the shipment on South African roads.
 Finally, a South African judge ruled that the ship could not dock as planned.
An Ammunition Column consists of dedicated military vehicles carrying artillery and small arms ammunition for the combatant unit to which the column belongs, most noted as being the Artillery Brigade or a Divisional Artillery.
 Thus the Ammunition Columns of a division, formed of the brigades of field artillery, carry reserve ammunition for the guns, the machine guns of the infantry and the rifles of all arms.
 Generally speaking, the Brigade Ammunition Column of the Artillery Brigades furnishes ammunition for its own batteries and for one of the brigades of infantry, and each is supported by a Divisional Artillery.
Millway railway station was a short lived railway station built by the London, Midland and Scottish Railway to serve ROF Radway Green in Cheshire.
The Lightweight Small Arms Technologies (LSAT) program is funded by the U.S. Joint Service Small Arms Program, with the goal of significantly reducing the weight of small arms and their ammunition.
 Following a series of military programs to investigate advances in small arms (the SPIW program, the Future Rifle Program, the ACR program, and the OICW program), the LSAT program is the US Military's latest project to replace existing US small arms.
 Tactical concepts and the research from the previous small arms programs indicates that lightening small arms is only the first significant step in small arms design towards increasing soldiers' lethality and survivability.
Green bullet, green ammunition or green ammo are nicknames for a United States Department of Defense program to eliminate the use of hazardous materials from small arms ammunition and from small arms ammunition manufacturing.
 Initial objectives were elimination of ozone-depleting substances, volatile organic compounds, and heavy metals from primers and projectiles.
 These materials were perceived as causing difficulties through the entire life cycle of ammunition.
 The materials generated hazardous wastes and emissions at manufacturing facilities and use of ammunition caused contamination at shooting ranges. Potential health hazards made demilitarization and disposal of unused ammunition difficult and expensive.
The LSAT light machine gun, of the LSAT (Lightweight Small Arms Technologies) program, is a developmental, powerful light machine gun (LMG).
 The purpose of the program was to develop a lighter, yet very reliable LMG.
 The program was initiated in 2004, when the Joint Service Small Arms Program (JSSAP) challenged the American defence industry to develop a lighter small arms and also design lighter ammunition.
 The LMG provides a major reduction in weight over legacy weapons, as well as improvements in other areas, such as controllability and reliability.
 As of 2008, it had two configurations, one that fires cased telescoped ammunition, and one that fires caseless ammunition.
 After further research and development into both technologies and the guns that fire them, one of the two variants was to be chosen for production.
 By May 2015, 85,000 cased-telescoped rounds had been fired through 10 test weapons, with testers claiming the weapon had gone as far as it can go until the Army decides if it wants to make it a program of record.
The United States Cartridge Company was an early manufacturer of cartridge ammunition for small arms.
 The company was founded in 1869 by American Civil War general Benjamin Butler.
 Company startup was during the most rapid evolution of cartridge design to date.
 Lowell, Massachusetts emerged as one of the most successful cartridge producers in the United States while Butler served as a congressman from Massachusetts from 1867 to 1879 and as governor from 1883 to 1884.
 After supplying 65 percent of American small arms ammunition production for World War I, the company was acquired by the owner of Winchester Repeating Arms; and the Lowell factory closed as manufacturing shifted to New Haven, Connecticut.
The former Royal Ordnance Factory (ROF), Radway Green manufactures small arms ammunition for the British armed forces.
 It is located in the hamlet of Radway Green near Barthomley near Alsager in Cheshire in the UK.
 The factory, which is now owned by BAE Systems Global Combat Systems, was established in 1940.
 It has manufactured a wide range of ammunition, including:
