section::::design and development.









































in 1900, john moses browning filed a patent for a recoil-powered automatic gun. browning did not work on the gun again until 1910, when he built a water-cooled prototype of the 1900 design. although the gun worked well, browning improved the design slightly. browning replaced side ejection with bottom ejection, added a buffer for smoother operation, replaced the hammer with a two piece firing pin, and some other minor improvements. the basic design of the gun was still the 1900 design.

the bradley is equipped with the m242 25 mm autocannon as its main weapon. the m242 has a single barrel with an integrated dual-feed mechanism and remote feed selection. the gun has 300 ready rounds in two ready boxes (one of 70 rounds – usually ap-type rounds, the other of 230 rounds – usually he-type rounds), with another 600 rounds in storage. the two ready boxes allow a selectable mix of rounds, such as the m791 apds-t (armor-piercing discarding sabot (with) tracer), and m792 hei-t (high explosive incendiary (with) tracer) rounds. the 25 mm automatic gun is primarily used for clearing bunkers and firing on lightly armored vehicles. while the 25 mm automatic gun is not the weapon of choice for engaging tanks, vehicle commanders, crews, and call and army infantry center personnel reported isolated instances in which the 25 mm automatic gun had killed tanks. however, army materiel systems analysis activity (amsaa) officials stated that, on the basis of their assessment of combat vehicles in the persian gulf war, for the 25 mm automatic gun to kill a tank, the tank would have to be hit at close range in its more vulnerable areas. subsequent ammunition developments resulted in the m919 apfsds-t (armor-piercing fin stabilized discarding sabot with tracer) round, which contains a finned depleted-uranium penetrator similar in concept to armor-piercing munitions used in modern tanks. the m919 was used in combat during the 2003 invasion of iraq.
