Editing BMP-3 (section)

=== Weaponry and optics ===
The BMP-3 is one of the most heavily armed infantry combat vehicles in service. The original version has a turret fitted with a low-velocity 2A70 100&nbsp;mm rifled gun which can fire conventional shells or [[9M117 Bastion]] Anti Tank Guided Missiles (AT-10 Stabber). It carries 40 100&nbsp;mm rounds and 8 ATGMs. A 2A72 30&nbsp;mm dual feed autocannon with 500 (300 [[High-explosive incendiary|HEI]] and 200 [[Armour-piercing ammunition|AP-T]]) rounds and a rate of fire of 350 to 400 rounds per minute and a 7.62&nbsp;mm [[PKT machine gun|PKT]] [[machine gun]] with 2,000 rounds are mounted coaxially in the turret. The main gun elevates from −5° to +60°.<ref>{{cite web |author=John Pike |url=http://www.globalsecurity.org/military/world/russia/bmp-3-specs.htm |title=BMP-3 Fighting Vehicle |publisher=Globalsecurity.org |date=2010-05-13 |access-date=2010-08-24 |archive-url=https://web.archive.org/web/20121104015925/http://www.globalsecurity.org/military/world/russia/bmp-3-specs.htm |archive-date=2012-11-04 |url-status=live }}</ref> There are also two 7.62&nbsp;mm PKT bow machine guns, again with 2,000 rounds each. The BMP-3 is capable of engaging targets out to 5,000–6,000 metres with its ATGM weapon system 9K116-3 "Basnya". With conventional ammunition, such as the [[High explosive|HE-Frag]] [[shell (projectile)|shell]] 3OF32, the 2A70 gun has a range of 4,000 metres.

According to the manufacturer's website, all weapons can be fired while still, on the move, and afloat with the same effectiveness. The ability to hit targets on the move with missiles was successfully demonstrated during competitive evaluations in the UAE in 1991.<ref>{{cite web |url=http://www.enemyforces.com/apc/bmp3.htm |title=Infantry Combat Vehicle BMP-3 |publisher=Enemyforces.com |date=1991-07-27 |access-date=2010-02-07 |archive-url=https://web.archive.org/web/20080723235819/http://www.enemyforces.com/apc/bmp3.htm |archive-date=2008-07-23 |url-status=live }}</ref>
