When the Lockheed P-38 Lightning, armed with four "light barrel" AN/M2 .50 cal. Browning machine guns and one 20 mm autocannon, and the Grumman F6F Hellcat and Vought F4U Corsair, each with six AN/M2 .50 calibre Browning guns, appeared in the Pacific theater, the A6M, with its low-powered engine and lighter armament, was hard-pressed to remain ...
The DTED format for level 0, 1 and 2 is described in U.S. Military Specification Digital Terrain Elevation Data (DTED) MIL-PRF-89020B, and amongst other parameters describes the resolution for each level: Level 0 has a post spacing of approximately 900 meters. Level 1 has a post spacing of approximately 90 meters.
QFE - is the barometric altimeter setting that causes an altimeter to read zero when at the reference datum of a particular airfield (in practice, the reference datum is either an airfield center or a runway threshold). In ISA temperature conditions the altimeter will read the height above the airfield/runway in the vicinity of the airfield.
A M2 Bradley configured for swimming, Fort Benning, June 1983. The M2 was the basic production model, designed to carry 10 person teams, first fielded in 1981. [56] The M2 can be identified by its standard TOW missile system, steel laminate armor, and 500 horsepower (370 kW) Cummins VT903 engine with HMPT-500 hydromechanical transmission. Basic ...

[12] In operation, maximum azimuth slew rate >100°/s, with maximum elevation slew Rate >50°/s. Range of Elevation −20° to +60° Protector Dual RWS. Protector Dual RWS mounts two weapons.
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods.
