The AN/PSG-2 and AN/PSG-2B Digital Message Device (DMD) are portable data-entry terminals manufactured by Magnavox and used by artillery forward observers to communicate with artillery batteries to request and control artillery fire missions. DMDs were first fielded as part of the TACFIRE artillery fire control system.
Magnavox is an American electronics company founded in the United States. Since 1974 it is a subsidiary of Dutch electronics corporation Philips.
Artillery is a class of heavy military weapons built to fire munitions far beyond the range and power of infantry's small arms. Early artillery development focused on the ability to breach defensive walls, and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the large share of an army's total firepower.
The original DMD allowed users to conduct fire missions, develop fire plans and send/receive freeform text messages. An enhanced version, the FIST (FIre Support Team) DMD, allowed a FIST Chief (usually an Artillery Lieutenant) to monitor the transmissions of his forward observers.
A lieutenant is a junior most commissioned officer in the armed forces, fire services, police and other organizations of many nations.
The accompanying illustration is from the Windows version of the MiniTSFO, a PC-based call for fire simulator developed in the late 1980s.
The Mini TSFO was the first artillery call-for-fire simulation designed for the personal computer. It was started in 1985 as an outgrowth of a Field Artillery Officer Advanced Course battlefield research project at the U.S. Army Field Artillery School (USAFAS) to develop a concept for incorporating PCs into artillery training, and was completed in 1986. It replaced summer artillery live fire training for cadets at West Point in 1986 and 1987.
A personal computer (PC) is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large costly minicomputer and mainframes, time-sharing by many people at the same time is not used with personal computers.
MIDI is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing and recording music. A single MIDI link through a MIDI cable can carry up to sixteen channels of information, each of which can be routed to a separate device or instrument. This could be sixteen different digital instruments, for example.
Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area. Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry. APRS data can be displayed on a map, which can show stations, objects, tracks of moving objects, weather stations, search and rescue data, and direction finding data.
Naval gun fire support (NGFS) is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term Naval Fires. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since medieval naval warfare.
DMD may refer to:
A military artillery observer or spotter or FO is responsible for directing artillery and mortar fire onto a target, and may be a Forward Air Controller (FAC) for close air support and spotter for naval gunfire support. Also known as "Fire Support Specialist" or "FISTer", an observer usually accompanies a tank or infantry manoeuvre unit. More recently a mission controller for an Army Unmanned Air System (UAS) may also perform this function, and some armies use special artillery patrols behind the enemy's forward elements. Spotters ensure that indirect fire hits targets which the troops at the fire support base cannot see.
Field artillery is a category of mobile artillery used to support armies in the field. These weapons are specialized for mobility, tactical proficiency, short range, long range, and extremely long range target engagement.
Forward air control is the provision of guidance to close air support (CAS) aircraft intended to ensure that their attack hits the intended target and does not injure friendly troops. This task is carried out by a forward air controller (FAC).
The United States Army Field Artillery School (USAFAS) trains Field Artillery Soldiers and Marines in tactics, techniques, and procedures for the employment of fire support systems in support of the maneuver commander. The school further develops leaders who are tactically and technically proficient, develops and refines warfighting doctrine, and designs units capable of winning on future battlefields. The school is currently located at Fort Sill, Oklahoma.
Fire discipline is a system of communication in the military, primarily for directing artillery. By definition, fire discipline is the language of fire control. It consists of words, phrases, rules, and conventions which have specific meanings and which result in some definite action being taken with the guns. All ranks concerned in fire control must be thoroughly familiar with the language and the resulting actions. The aim of fire discipline is to ensure that in response to calls for fire, the appropriate action is taken at the FPC, FSCC, CP and at the Guns/MRL, strictly in accordance with the intentions of the originator and with the minimum of delay.
In the land-based field artillery, the field artillery team is organized to direct and control indirect artillery fire on the battlefield. Since World War I, to conduct indirect artillery fire, three distinct components have evolved in this organization: the forward observer, the fire direction center (FDC) and what is called the gun line. On the battlefield, the field artillery team consists of some combinations of all of these elements. In other words, there may be multiple FOs calling in fire on multiple targets to multiple FDCs and any component may be in communication with some of the other elements depending on the situational requirements.
The gun data computer was a series of artillery computers used by the U.S. Army for coastal artillery, field artillery and antiaircraft artillery applications. In antiaircraft applications they were used in conjunction with a director.
The M981 FISTV is a United States Army armored vehicle designed to house an artillery observer team in mechanized units. It was based on the M901 Improved TOW Vehicle (ITV) - itself based on the ubiquitous M113 Armored Personnel Carrier chassis - and outwardly closely resembles it, so as to make it less conspicuous on the battlefield.
The Fire Support Vehicle (FSV) of the Stryker series provides automated enhanced surveillance, target acquisition, target identification, target tracking, target designation, position location and communications functionality. Targets will be transmitted instantly to the fire support system and shooter.
Sanomalaite M/90 (SANLA) is a digital, portable and encrypted text-based communications device developed by Nokia and used by all branches of Finnish Defence Forces.
The 2K25 Krasnopol is a Soviet 152/155 mm cannon-launched, fin-stabilized, base bleed-assisted, semi-automatic laser-guided, artillery weapon system. It automatically 'homes' on a point illuminated by a laser designator, typically operated by a ground-based artillery observer. Krasnopol projectiles are fired mainly from Soviet self-propelled howitzers such as the 2S3 Akatsiya and 2S19 Msta-S and intended to engage small ground targets such as tanks, other direct fire weapons, strong-points, or other significant point targets visible to the observer. It can be used against both stationary and moving targets.
The digital micromirror device, or DMD, is the micro-opto-electromechanical system (MOEMS) that is the core of the trademarked DLP projection technology from Texas Instruments (TI). The DMD was invented by solid state physicist and TI Fellow Emeritus Dr. Larry Hornbeck in 1987.
Forward observers in the U.S. military are artillery observers who carry the Military Occupational Specialty designator of 13F in the United States Army and 0861 in the United States Marine Corps. They are officially called Joint Fire Support Specialists in the U.S. Army and Fire Support Men in the U.S. Marine Corps. They are colloquially known as FiSTers, regardless of whether they are members of a FiST. The Battalion Fire Support Officer (FSO) is the Officer in Charge of a Battalion Fire Support Element.
