Signal operating instructions (SOI) or Communications-Electronics Operation Instructions (CEOI) are U.S. military terms for a type of combat order issued for the technical control and coordination of communications within a command. [1] They include current and up-to-date information covering radio call signs and frequencies, a telephone directory, code-words (for rudimentary encryption), and visual and sound signals. A designated battalion signal officer prepares the battalion SOI in conformance with the SOI of higher headquarters. [2] During operations, SOI are changed daily. Since the fielding of the SINCGARS system, however, the paper SOI has generally faded from Army use. Electronic SOI are now generated, distributed and loaded along with cryptographic keys. [3]
The title SOI was used until the early 1970s and it was changed to CEOI and then changed back to SOI in the 1980s.
Signals intelligence (SIGINT) is intelligence-gathering by interception of signals, whether communications between people or from electronic signals not directly used in communication. Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again.
Communications security is the discipline of preventing unauthorized interceptors from accessing telecommunications in an intelligible form, while still delivering content to the intended recipients.
The Q-code is a standardised collection of three-letter codes that each start with the letter "Q". It is an operating signal initially developed for commercial radiotelegraph communication and later adopted by other radio services, especially amateur radio. To distinguish the use of a Q-code transmitted as a question from the same Q-code transmitted as a statement, operators either prefixed it with the military network question marker "INT" or suffixed it with the standard Morse question mark UD.
The School of Infantry (SOI) is the second stage of initial military training for enlisted United States Marines after recruit training. Since the initial training pipeline is divided between coasts, Marines from areas east of the Mississippi River usually graduate from MCRD Parris Island and move on to SOI at SOI East, while those from the western half of the nation attend MCRD San Diego and move on to SOI West at the Camp San Onofre area of Camp Pendleton in California. Female Marines are trained at both SOI East and SOI West. The School of Infantry's training mission ensures "Every Marine is, first and foremost, a Rifleman". At SOI, Marines with the Military Occupational Specialty of infantry are trained at the Infantry Training Battalion (ITB), while all non-infantry Marines are trained in basic infantry and combat skills at the Marine Combat Training Battalion. SOI marks a transition in the professional training of entry-level students from basically trained Marines to combat-ready Marines.
The United States Army Space and Missile Defense Command (USASMDC) is an Army Service Component Command (ASCC) of the United States Army. The command was established in 1997. The current USASMDC commander is Lieutenant General Daniel L. Karbler with Senior Enlisted Advisor Command Sergeant Major Finis A. Dodson.
A military staff or general staff is a group of officers, enlisted and civilian staff who serve the commander of a division or other large military unit in their command and control role through planning, analysis, and information gathering, as well as by relaying, coordinating, and supervising the execution of their plans and orders, especially in case of multiple simultaneous and rapidly changing complex operations. They are organised into functional groups such as administration, logistics, operations, intelligence, training, etc. They provide multi-directional flow of information between a commanding officer, subordinate military units and other stakeholders. A centralised general staff results in tighter top-down control but requires larger staff at headquarters (HQ) and reduces accuracy of orientation of field operations, whereas a decentralised general staff results in enhanced situational focus, personal initiative, speed of localised action, OODA loop, and improved accuracy of orientation.
The United States Army Signal Corps (USASC) is a branch of the United States Army that creates and manages communications and information systems for the command and control of combined arms forces. It was established in 1860, the brainchild of Major Albert J. Myer, and had an important role in the American Civil War. Over its history, it had the initial responsibility for portfolios and new technologies that were eventually transferred to other U.S. government entities. Such responsibilities included military intelligence, weather forecasting, and aviation.
The 11th Corps Signal Brigade of the United States Army is an element of Army Forces Command. It is based at Fort Hood, Texas. The unit mascot is the Thunderbird, a hawk-like bird perched upon a globe shooting thunderbolts out of its eyes. Soldiers in this unit call themselves "The Thunderbirds."
An Operation Order, often abbreviated to OPORD, is a plan format meant to assist subordinate units with the conduct of military operations. An OPORD describes the situation the unit faces, the mission of the unit, and what supporting activities the unit will conduct in order to achieve their commander's desired end state. Normally an OPORD is generated at the battalion, regimental, brigade, divisional, or corps headquarters and disseminated to its assigned or attached elements. The issuance of an OPORD triggers subordinate unit leadership to develop orders specific to the role or roles that the unit will assume within the operation. This more narrowly focused order borrows information from the original, or base, order and adds additional details that pertain more to the minutiae of the actions a unit is tasked to conduct in support of the overarching operation.
In the United States Army, the term combat support refers to units that provide fire support and operational assistance to combat elements. Combat support units provide specialized support functions to combat units in the following areas
The Myanmar Army is the largest branch of the Armed Forces (Tatmadaw) of Myanmar (Burma) and has the primary responsibility of conducting land-based military operations. The Myanmar Army maintains the second largest active force in Southeast Asia after the People's Army of Vietnam.
The Command Support Regiment is a regiment of the Royal Danish Army. It was established in 1951 with the purpose of training and equipping units to support the Danish army with wartime Command, Control and Communications. Until 1 January 2019 the unit was known as Signal Regiment Danish: Telegrafregimentet). Today the battalions filled by the regiment set up the command, control and communications infrastructure of the army by setting up a vehicle-based microwave radio relay network in a mesh topology. The network is designed to be secure, encrypted and difficult to neutralize. Besides the radio network, the regiment also establishes mobile military headquarters to be used by the army.
The 25th Signal Battalion is a strategic signal battalion (SSB) of the United States Army. The battalion is one of two permanently assigned to the 160th Signal Brigade.
The 261st Theater Tactical Signal Brigade is a unit in the Delaware Army National Guard, with a home station in Smyrna, Delaware. The 261st Theater Tactical Signal Brigade provides command and control to assigned and attached units. The 261st Signal Brigade supervises the installation, operation, and maintenance of up to 16 NODES in the theater communications system excluding the division and corps systems. The brigade also hosts a Joint Command, Control, Computer and Communications (C4) Center, or JCCC, at its headquarters in Smyrna, Delaware.
The Special Forces Qualification Course (SFQC) or, informally, the Q Course is the initial formal training program for entry into the United States Army Special Forces. Phase I of the Q Course is Special Forces Assessment and Selection (SFAS). Getting "Selected" at SFAS will enable a candidate to continue to the next of the four phases. If a candidate successfully completes all phases they will graduate as a Special Forces qualified soldier and then, generally, be assigned to a 12-men Operational Detachment "A" (ODA), commonly known as an "A team." The length of the Q Course changes depending on the applicant's primary job field within Special Forces and their assigned foreign language capability but will usually last between 56 and 95 weeks.
The AN/CYZ-9 is a hardware random number generator fielded by the US National Security Agency in the 1990s. It was used in initial phases of the US military's Electronic Key Management System (EKMS) Tier 2. These systems employ a commercial or militarized personal computer running MS-DOS to generate cryptographic keys and signal operating instructions (SOI/CEOI), with the CYZ-9 producing the needed random bits. The CYZ-9 connects to the PC through an RS-232 port and is powered by five D cell (BA-30) batteries. In later phases of EKMS, the random data functionality is included in an NSA key processor (KP).
112th Special Operations Signal Battalion (Airborne) is part of the 528th Sustainment Brigade and specializes in supporting United States Army Special Operations Command (USASOC) forces.
16-line message format, or Basic Message Format, is the standard military radiogram format for the manner in which a paper message form is transcribed through voice, Morse code, or TTY transmission formats. The overall structure of the message has three parts: HEADING, TEXT, and ENDING. This heading is further divided into procedure, preamble, address, and prefix. Each format line contains pre-defined content. An actual message may have fewer than 16 actual lines, or far more than 16, because some lines are skipped in some delivery methods, and a long message may have a TEXT portion that is longer than 16 lines by itself.
The QSA code and QRK code are interrelated and complementary signal reporting codes for use in wireless telegraphy. An enhanced format, SINPO code, was published in the ITU Radio Regulations, Geneva, 1959, but is longer and unwieldy for use in the fast pace of Morse code communications.
The Signal Command is a signals formation of the Italian Army. The Signal Command was established in Rome on 1 January 2017 following the disestablishment of the Army Information and Signals Command and of the Signals Brigade.
