30mmvs556nato
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th c ...

Mi-28
The Mil Mi-28 (NATO reporting name "Havoc") is a Soviet all-weather, day-night, military tandem, two-seat anti-armor attack helicopter. It is an attack helicopter with no intended secondary transport capability, and is better optimized than the Mil Mi-24 gunship for the role. It carries a single gun in an undernose barbette, plus external loads carried on pylons beneath stub wings. Development Origins In 1972, following the completion of the Mil Mi-24, development began on a unique attack helicopter with transport capability. The new design had a reduced transport capability (3 troops instead of 8) and omitted the cabin to provide better overall performance and higher top speed. Improved performance was important for its intended role fighting against tanks and enemy helicopters and covering helicopter landing operations. Initially, many different designs were considered, including an unconventional project with two main rotors, placed with engines on tips of wings (in ...

Expeditionary Fighting Vehicle
The Expeditionary Fighting Vehicle (EFV) (formerly known as the Advanced Amphibious Assault Vehicle (AAAV)) was an amphibious assault vehicle developed by General Dynamics during the 1990s and 2000s for use by the US Marine Corps. It would have been launched at sea, from an amphibious assault ship beyond the horizon, able to transport a full marine rifle squad to shore. It would maneuver cross country with an agility and mobility equal to or greater than the M1 Abrams. The EFV was designed to replace the aging AAV-7A1 Assault Amphibious Vehicle (AAV), which entered service in 1972, and was the Marine Corps' number one priority ground weapon system acquisition. It was to have had three times the speed in water and about twice the armor of the AAV, as well as superior firepower. The vehicle was to be deployed in 2015; however, on 6 January 2011, Secretary of Defense Robert Gates recommended the EFV program be canceled. The program, which was projected to cost $15 billio ...
