  2. Explosives safety - Wikipedia

    en.wikipedia.org/wiki/Explosives_safety

    Quantity-distance (QD) is the foundation of DOD explosives safety standards. It defines levels of protection from blast based on relationships between the quantity of explosive material (NEW) and distance. The relationships are based on levels of risk considered acceptable for specific exposures but they do not provide absolute safety or ...

  3. Radius of action - Wikipedia

    en.wikipedia.org/wiki/Radius_of_action

    Radius of action, combat radius, or combat range in military terms, refers to the maximum distance a ship, aircraft, or vehicle can travel away from its base along a given course with normal load and return without refueling, allowing for all safety and operating factors. [1]

    The relation between and are given by the following table, where the values for DRMS and 2DRMS (twice the distance root mean square) are specific to the Rayleigh distribution and are found numerically, while the CEP, R95 (95% radius) and R99.7 (99.7% radius) values are defined based on the 68–95–99.7 rule

  6. Tactical air navigation system - Wikipedia

    en.wikipedia.org/wiki/Tactical_air_navigation_system

    A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system initially designed for naval aircraft to acquire moving landing platforms (i.e., ships) and later expanded for use by other military aircraft. It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne ...

  7. Effective range - Wikipedia

    en.wikipedia.org/wiki/Effective_range

    With the addition of clinometers fixed machine gun squads could set long ranges and deliver plunging fire or indirect fire at more than 2,500 m (2,730 yd). This indirect firing method exploits the maximal practical range, that is defined by the maximum range of a small-arms projectile while still maintaining the minimum kinetic energy required to put unprotected personnel out of action, which ...

  8. Global Area Reference System - Wikipedia

    en.wikipedia.org/wiki/Global_Area_Reference_System

    Under the Chairman of the Joint Chiefs of Staff Instruction CJCSI 3900.01C dated 30 June 2007, GARS was adopted for use by the US DoD as "the “area-centric” counterpart to the “point-centric” MGRS". It uses the WGS 1984 Datum and is based on lines of longitude (LONG) and latitude (LAT). It is intended to provide an integrated common ...

  9. Military Grid Reference System - Wikipedia

    en.wikipedia.org/wiki/Military_Grid_Reference_System

    The Military Grid Reference System (MGRS) [1] is the geocoordinate standard used by NATO militaries for locating points on Earth. The MGRS is derived from the Universal Transverse Mercator (UTM) grid system and the Universal Polar Stereographic (UPS) grid system, but uses a different labeling convention.
