Combat ( French for fight ) is a purposeful violent conflict between multiple combatants with the intent to harm the opposition. Combat may be armed (using weapons ) or unarmed ( not using weapons ). Combat is resorted to either as a method of self-defense or to impose one's will upon others. An instance of combat can be a standalone confrontation or part of a wider conflict, and its scale can range from a fight between individuals to a war between organized groups. Combat may also be benign and recreational , as in the cases of combat sports and mock combat .

54-402: A ranged weapon . Hand-to-hand combat can be further divided into three sections depending on the distance and positioning of the combatants: Military combat always involves between two or more opposing military forces in warfare . Military combat situations can involve multiple groups, such as guerilla groups, insurgents , domestic and/or foreign governments . A military combat situation
81-545: A fighter category F incorporates not only aircraft designed primarily for air-to-air warfare, but also multipurpose aircraft designed also for attack missions. The Air Force has even assigned the F designation to attack-only aircraft, such as the F-111 Aardvark and F-117 Nighthawk . The only A designated aircraft currently in the U.S. Air Force is the A-10 Thunderbolt II . The last front line A designated in
108-429: A particular design are assigned a modified mission code. They are: The multi-mission and utility missions could be considered the same thing; however they are applied to multipurpose aircraft conducting certain categories of mission. M-aircraft conduct combat or special operations while U-aircraft conduct combat support missions, such as transport (e.g., UH-60 ) and electronic warfare (e.g., MC-12 ). Historically,
135-572: A project but the aircraft was never built. The following table lists design numbers in the 1962 system which have been skipped. Since 1939, a 2-letter manufacturer's code has been added to designations to identify the manufacturer and the production plant. For example, F-15E-50-MC, the "MC" being the code for the McDonnell Douglas plant at St. Louis, Missouri. In 1941, block numbers were added to designations to show minor equipment variations between production blocks. The block number appears in

189-529: A unified designation, whether they are operated by the United States Air Force (USAF), United States Navy (USN), United States Marine Corps (USMC), United States Army , United States Space Force (USSF), or United States Coast Guard (USCG). Experimental aircraft operated by manufacturers or by NASA are also often assigned designations from the X-series of the tri-service system. The 1962 system
216-552: Is different from Wikidata All article disambiguation pages All disambiguation pages RQ series The Tri-Service aircraft designation system is a unified system introduced in 1962 by the United States Department of Defense for designating all U.S. military aircraft . Previously, the U.S. armed services used separate nomenclature systems . Under the tri-service designation system, officially introduced on 18 September 1962, almost all aircraft receive
243-448: Is known either as a battle or a war, depending on the size of the fighting and which geographical areas in which it occurs. Combat effectiveness has always demanded that the personnel maintain strategic preparedness by being sufficiently trained , armed , equipped , and funded to carry out combat operations in the unit to which they are assigned. Warfare falls under the law of war , which govern its purposes and conduct, and protect
270-469: Is more suitable (e.g., M in MH-53J Pave Low III ). The defined codes are: The rise of the multirole fighter in the decades since the system was introduced has created some confusion about the difference between attack and fighter aircraft. According to the current designation system, an attack aircraft ( A ) is designed primarily for air-to-surface missions (also known as "attack missions"), while
297-495: Is no longer used but was meant to designate aircraft "on the drawing board". For example, using this system an airframe such as the F-13 could have initially been designated as ZF-13 during the design phase, possibly XF-13 if experimental testing was required before building a prototype, the YF-13; the final production model would simply be designated F-13 (with the first production variant being
SECTION 10
#1732898332130324-613: Is required to merit a new series letter, e.g., the F-16C production run has varied extensively over time. The modification of an aircraft to carry out a new mission does not necessarily require a new suffix (e.g., F-111Cs modified for reconnaissance are designated RF-111C), but often a new letter is assigned (e.g., the UH-60As modified for Search and Rescue missions are designated HH-60G ). Some series letters have been skipped to forestall confusion with pre-1962 naval designations; for instance, there
351-534: The Geneva Conventions (covering the treatment of people in war), medieval chivalry , the Marquess of Queensberry Rules (covering boxing), and the individual rulesets of various combat sports. Hand-to-hand combat ( melee ) is combat at very close range, attacking the opponent with the body ( striking , kicking , strangling , etc.) and/or with a melee weapon ( knives , swords , batons , etc.), as opposed to
378-464: The F-13A). Continuing the example, some F-13s during their service life may have been used for testing modifications or researching new designs and designated JF-13 or NF-13; finally after many years of service, the airframe would be permanently grounded due to safety or economic reasons as GF-13. Aircraft which are modified after manufacture or even built for a different mission from the standard airframe of
405-447: The Navy, and Marine Corps refer to it as Type/Model/Series (T/M/S). These optional prefixes are attached to aircraft not conducting normal operations, such as research, testing and development. The prefixes are: A temporary special test means the aircraft is intended to return to normal service after the tests are completed, while permanent special test aircraft are not. The Planning code
432-735: The Tri-Service system was partly brought about due to Secretary of Defense Robert McNamara 's confusion and frustration with the different designation systems the Navy and Air Force used at the time which resulted in the F4H and F-110 both being used to refer to, essentially, the same aircraft. The Tri-Service aircraft designation system was presented alongside the 1963 rocket and guided missile designation system in Air Force Regulation (AFR) 82-1/Army Regulation (AR) 70-50/Naval Material Command Instruction (NAVMATINST) 8800.4A (published 27 March 1974) and
459-592: The U.S. Navy and Marine Corps was the A-6 Intruder , with the only strictly A designated fixed-wing aircraft remaining is the A-29 Super Tucano leased under the Imminent Fury program. Of these code series, no normal aircraft have been assigned a K or R basic mission code in a manner conforming to the system. The vehicle type element is used to designate the type of aerospace craft. Aircraft not in one of
486-546: The designation between the model suffix and manufacturers code (for example F-100D-85-NH). Initially, they incremented in numerical order −1, −2, −3 but this was changed to −1, −5, −10, −15 in increments of five. The gaps in the block numbers could be used for post-delivery modifications—for example, a F-100D-85-NH could be modified in the field to F-100D-86-NH. Not all types have used block numbers. Combat Combat may comply with, or be in violation of, local or international laws regarding conflict. Examples of rules include
513-493: The following categories (most fixed-wing aircraft) are not required to carry a type designator. The type categories are: A UAV control segment is not an aircraft, it is the ground control equipment used to command a UAV. Only in recent years has an aircraft been designated as a spaceplane, the proposed MS-1A . According to the designation system, aircraft of a particular vehicle type or basic mission (for manned, fixed-wing, powered aircraft) were to be numbered consecutively, and
540-519: The model number (e.g., KC-767A ) or have kept the design number when they are transferred from one series to another (e.g., the X-35 became the F-35 ). Different versions of the same basic aircraft type are to be delineated using a single letter suffix beginning with " A " and increasing sequentially (skipping " I " and " O " to avoid confusion with the numbers " 1 " and " 0 "). It is not clear how much modification
567-463: The number series were restarted, causing some redesignated naval aircraft and subsequent new designs to overlap disused USAAC/USAAF designations (e.g., the Lockheed F-5 and Northrop F-5 ). Numbers were not to be assigned to avoid confusion with other letter sequences or to conform with manufacturers' model numbers. Recently this rule has been ignored, and aircraft have received a design number equal to

#1732898332130594-457: The order of the letters or use new acronym based letters (e.g. SR) rather than existing ones. Non-systematic designations are both official and correct, since the DOD has final authority to approve such designations. The design number " 13 " has been skipped in many mission and vehicle series for its association with superstition . Some numbers were skipped when a number was requested and/or assigned to
621-419: The two systems have been concurrently presented and maintained in joint publications since. The most recent changes were mandated by Joint Regulation 4120.15E Designating and Naming Military Aerospace Vehicles and were implemented via Air Force Instruction (AFI) 16-401, Army Regulation (AR) 70-50, Naval Air Systems Command Instruction (NAVAIRINST) 13100.16 on 3 November 2020. The list of military aircraft
648-518: The vast majority of U.S. Coast Guard air assets included the H-code (e.g., HH-60 Jayhawk or HC-130 Hercules ). In the 21st century, the Coast Guard has used the multi-mission designation for their armed rescue helicopters ( MH-60 Jayhawk or MH-65 Dolphin ). All aircraft are to be assigned a basic mission code. In some cases, the basic mission code is replaced by one of the modified mission codes when it
675-651: Was based on the one used by the USAF between 1948 and 1962, which was in turn based on the type, model, series USAAS/USAAC/USAAF system used from 1924 to 1948. The 1962 system has been modified and updated since introduction. The Tri-Service system was first enacted on 6 July 1962 by the DoD Directive 4505.6 "Designating, Redesignating, and Naming Military Aircraft" and was implemented via Air Force Regulation (AFR) 66-11, Army Regulation (AR) 700-26, Bureau of Weapons Instruction (BUWEPSINST) 13100.7 on 18 September 1962. Anecdotally,
702-517: Was maintained via 4120.15-L Model Designation of Military Aerospace Vehicles until its transition to data.af.mil on 31 August 2018. The system uses a Mission-Design-Series (MDS) designation of the form: Of these components, only the Basic Mission , Design Number and Series Letter are mandatory. In the case of special vehicles a Vehicle Type symbol must also be included. The U.S. Air Force characterizes this designation system as "MDS", while
729-465: Was no "H" version of the F-4 Phantom II because the aircraft type was previously designated F4H. Since the 1962 system was introduced there have been several instances of non-systematic aircraft designations and skipping of design numbers. The most common changes are to use a number from another series, or some other choice, rather than the next available number (117, 767, 71). Another is to change
