There are 2 pictures of the BMP 1 and 2. BMP 1 : The BMP-1 is a Soviet amphibious tracked infantry fighting vehicle, in service 1966–present . BMP stands for Boyevaya Mashina Pyekhoty 1 (Russian: Боевая Машина Пехоты 1; БМП-1), meaning "infantry fighting vehicle, 1st serial model"1. It was the first mass-produced infantry fighting vehicle (IFV) of the Soviet Union. The BMP-1 was designed in the early 1960s to replace BTR-50P series tracked APCs and was first seen in public in 1967. It was replaced in production by BMP-2 ICV, which, although similar in appearance, has a slightly different layout and new turret and weapon system. The BMP-1 has a crew of three (commander, driver and gunner) plus eight passengers. It is equipped with a 73 mm 2A28 Grom smoothbore gun (40 rounds), a 9M14 Malyutka ATGM (4 rounds), and a 7.62 mm PKT coaxial machine gun (2,000 rounds)1. The BMP-1 has a UTD-20 V6 diesel engine that produces 300 hp (224 kW) at 2,600 rpm1. It has a maximum speed of 65 km/h on road and 45 km/h off-road13. The BMP-1 has been used in various conflicts around the world including the Soviet-Afghan War, the Gulf War, the Iraq War, and the Syrian Civil War. BMP 2 : Although the BMP-1 was a revolutionary design, its main armament, the 2A28 Grom and the 9S428 ATGM launcher capable of firing 9M14 Malyutka (NATO: AT-3A Sagger A) and 9M14M Malyutka-M (NATO: AT-3B Sagger B) ATGMs, quickly became obsolete. Therefore, the Soviet Union decided to produce an updated and improved version of the BMP-1. The main emphasis was put on improving the main armament. In 1972, work got under-way to develop an improved version of the BMP-1. During its combat debut in the Yom Kippur War, Egyptian and Syrian BMPs proved vulnerable to .50 calibre machine-gun fire in the sides and rear, and to 106 mm M40 recoilless rifles. The 2A28 Grom proved inaccurate beyond 500 metres, and the 9M14 Malyutka missile could not be guided effectively from the confines of the turret. Several Soviet technical teams were sent to Syria in the wake of the war to gather information. These lessons, combined with observations of western AFV developments, resulted in a replacement project for the original BMP in 1974. The result was the BMP-1P upgrade, which was intended as a stopgap to address the most serious problems with the existing design. Smoke grenade launchers were added to the rear of the turret and the manually guided 9M14 Malyutka missile system was replaced with the semi-automatically guided 9K111 / 9M113 Konkurs system. The BMP-1P was in production by the late 1970s. Existing BMP-1s were gradually upgraded to the BMP-1P standard during the 1980s. Facts about BMP 2 : The commander now sits with the gunner in an enlarged, two-man turret. Armament changed to the 2A42 30 mm autocannon and the 9P135M ATGM launcher capable of firing SACLOS guided 9M111 (AT-4 Spigot), 9M113 "Konkurs" (AT-5 Spandrel) and 9M113M "Konkurs-M" (AT-5B Spandrel B) anti-tank missiles. Only seven troops can be carried instead of eight. Two rear infantry roof hatches instead of four. Slightly improved armor.
