NESTOR (encryption)
NESTOR was a family of compatible, tactical, wideband secure voice systems developed by the U.S. National Security Agency and widely deployed during the Vietnam War (1955–1975) through the late Cold War period (1980s–1990s). NESTOR consists of three systems. The KY-8 was used in vehicular and afloat applications; the KY-28 was the airborne version; and the KY-38 was the portable or man-pack model. About 30,000 NESTOR equipments were produced prior to their replacement by the VINSON secure voice family.A History of U.S. Communications Security; the David G.

RT-841
RT-841 is the base component VHF radio transceiver used by the United States military in manpack and vehicular radio configurations, including the AN/PRC-77 (manpack), AN/VRC-64 (vehicular) and the AN/GRC-160 (vehicular with manpack accessories). These radio systems were employed in the US Army and US Marine Corps from the Vietnam Era to the present. A follow-on radio system and ultimate replacement for this transceiver is the SINCGARS Single Channel Ground and Airborne Radio System (SINCGARS) is a VHF combat network radio (CNR) used by U.S. and allied military forces. In the CNR network, the SINCGARS’ primary role is voice transmission between surface and airborne comman ....

Combat-net Radio
In telecommunications, a combat-net radio (CNR) is a radio operating in a network that (a) provides a half-duplex circuit and (b) uses either a single radio frequency or a discrete set of radio frequencies when in a frequency hopping mode. CNRs are primarily used for push-to-talk-operated radio nets for command and control of combat, combat support, and combat service support operations among military ground, sea, and air forces. In the United States, two military standards govern the use of combat net radios and the host applications that communicate over the network: MIL-STD-188-220 and MIL-STD-2045-47001. In addition to IETF RFCs governing UDP, TCP, and IPv4/IPv6, all seven layers of the OSI communications architecture are addressed. MIL-STD-2045-47001 covers layer 7 ( application), while MIL-STD-188-220 covers layers 1 through 3 ( physical, data link, and network).

SINCGARS
Single Channel Ground and Airborne Radio System (SINCGARS) is a VHF combat network radio (CNR) used by U.S. and allied military forces. In the CNR network, the SINCGARS’ primary role is voice transmission between surface and airborne command and control (C2) assets. The SINCGARS family replaced the Vietnam War-era synthesized single frequency radios ( AN/PRC-77 and AN/VRC-12), although it can work with them. The airborne AN/ARC-201 radio is phasing out the older tactical air-to-ground radios (AN/ARC-114 and AN/ARC-131). The SINCGARS is designed on a modular basis to achieve maximum commonality among various ground, maritime, and airborne configurations. A common receiver/transmitter (RT) is used in the ground configurations. The modular design also reduces the burden on the logistics system to provide repair parts. The SINCGARS can operate in either the single-channel (SC) or frequency hopping (FH) mode, and stores both SC frequencies and FH loadsets. The system is compa ...

Joint Electronics Type Designation System
The Joint Electronics Type Designation System (JETDS), which was previously known as the Joint Army-Navy Nomenclature System (AN System. JAN) and the Joint Communications-Electronics Nomenclature System, is a method developed by the U.S. War Department during World War II for assigning an unclassified designator to electronic equipment. In 1957, the JETDS was formalized in MIL-STD-196. Computer software and commercial unmodified electronics for which the manufacturer maintains design control are not covered. Applicability Electronic material, from a military point of view, generally includes those electronic devices employed in data processing, detection and tracking (underwater, sea, land-based, air and space), recognition and identification, communications, aids to navigation, weapons control and evaluation, flight control, and electronics countermeasures. The JETDS applies to equipment throughout the DoD and select NATO allies today. Nomenclature is assigned to: * Electronic ...

Austrian Federal Army
The Austrian Armed Forces () are the combined military forces of Austria. The military consists of 16,000 active-duty personnel and 125,600 reservists. The military budget is 1.0% of national GDP (including pensions) or €3.317 billion (2023,without pensions). History Interwar In 1918, the Republic of German-Austria established a military known as the ("People's Defence"). ''Volkswehr'' forces took part in military confrontations with Royal Yugoslav Army troops which occupied parts of Carinthia that Austria claimed as its own. In 1920, after the Republic of German-Austria transitioned into the First Austrian Republic, the new regime changed the military's name to the ("Federal Army"), which it has been known by ever since. In 1938, officers led by Alfred Jansa developed a military operation plan to defend against a potential invasion by Nazi Germany, which ultimately went unused due to a lack of political willpower when Austria was annexed by the Germans in th ...

Bangladesh Army
The Bangladesh Army () is the land warfare branch, and the largest component of the Bangladesh Armed Forces. The primary mission of the Army is to defend the land of Bangladesh from any external attack. Control of personnel and operations is administered by the Army Headquarters, Dhaka Cantonment. The Bangladesh Army is also constitutionally obligated to assist the government, during times of domestic national emergency e.g. the army helps people during any natural calamity. This additional role is commonly referred to as "aid to civil administration" or, using the Latin form, "Protectio, Transparentia, Reintegratio", in other words, "Protect and Serve". History Early history The martial tradition of Bengal has its roots in the army of Kings and their chiefs, who were called Senapati or Mahasenapati. Armies were composed of infantry, cavalry, war elephants and war boats. The arrival of Muslims and the establishment of the Bengal Sultanate further strengthened the mili ...

Whip-a-way
{{Unreferenced, date=May 2019, bot=noref (GreenC bot) The Whip-a-way was a type of folding whip antenna. It was popular with users of Citizens band radio, and also had military uses. Versions Consumer The Whip-a-way is a seven-section, tubular, folding whip antenna. A plastic-covered cable (or braided plastic cord) under spring tension is threaded through the sections to keep them together when assembled for operation and prevent their separation or loss when disassembled. Spring tension is provided by a spiral spring in the base section. An antenna top cap installed on the tip of the antenna provides protection for personnel. The construction is the same as is used for sectional fishing poles. The base has a male 3/8-24 thread which is the same as is used on most ham radio and CB antennas. The antenna was 9 feet long when fully assembled. The product was distributed by South Shore Distributing of Hempstead, New York The Town of Hempstead is the largest of the three towns in N ...
