50-629: Field Artillery (or FA ) is a professionally published magazine on the subject of field artillery , published from 1911 to 2007, and after a brief hiatus now published quarterly. It is published by the US Field Artillery Association, headquartered at Fort Sill , Oklahoma . It was an official publication of the United States Army Field Artillery Corps . Its intended readership included active and reserve U.S. Army and Marine field artillerymen stationed around

100-522: A forward observer , who sees the target and relays the coordinates of the target to their fire direction center , which in turn translates those coordinates into: a left-right aiming direction; an elevation angle; a calculated number of bags of propellant; and finally a fuze with a determined waiting time before exploding (if necessary) to be set, which is then mated to the artillery projectile now ready to be fired. Modern field artillery (i.e. post- World War I ) has three distinct sections: All batteries have

150-428: A "barbarian attacking cannon" consisting of a cannon attached to a two-wheel carriage. Before World War I , field artillery batteries generally fired directly at visible targets measured in distances of meters and yards. Today, modern field batteries measure targets in kilometers and miles and often do not directly engage the enemy with observed direct fire . The hundredfold increase in the range of artillery guns in

200-499: A Fire Support Man (Forward Observer), Fire Direction Control (FDC), and Cannoners (Gunner). The FOs are forward with the infantry (in support role) where they can see the targets and Call For Fire (CFF) upon them. They call the FDC on the radio and transmit a request for fire in the format of CFF. The FDC calculates the CFF and send a deflection and elevation to the gun line. The gun line cranks

250-568: A blurring of these distinctions in the British army, tradition remained strong in the cavalry arm of some other nations. As an example, the Imperial German army maintained a marked difference between the sizes and weights of the men and horses allocated to the hussar regiments that made up its light cavalry and those of the other two categories. The early weeks of World War I saw light cavalry attempting to continue its long established function of being

300-525: A brief target description, a recommended munition to use, and any special instructions such as "danger close" (the warning that friendly troops are within 600 meters of the target when using artillery, requiring extra precision from the guns). The FO and the battery iteratively "walk" the fire onto the target. The Fire Direction Center (FDC) signals the FO that they have fired and the FO knows to observe fall of shot. He then signals corrections. These are normally of

350-499: A key role in mounted scouting, escorting, and skirmishing during the Napoleonic era. Light horse also served a function in major set-piece battles. While lacking the sheer offensive power of heavy cavalry, light cavalry were still extremely effective against unprepared infantry, cavalry, and artillery. All infantry commanders were forced to respect the danger any cavalry presented to their forces, and light cavalry were effective at changing

400-526: A location where they can be Fire Capability for some certain amount of time and do multiple fire missions before needing to displace. In normal operations the FOs locate targets and transmits the CFF to the FDCs. They can also calculate "defensive fire" tasks. These are pre‑planned missions, typically just in front of or upon one's own positions, designed with the intention of either suppressing potential attacks (where fire

450-555: A target identified by the FO. In most Artillery Batteries the Command Post (CP) controls the firing of the guns. It is usually located at the battery center so as to be able to communicate easily with the guns. The CP should be well camouflaged, but the CPO (Command Post Officer) should be able to see all the guns with ease. Gun markers are sometimes placed in front of the CP to remind the CPO which gun

500-406: Is continuous throughout advance party operations. Once a location is determined to be safe the advance party prepares the position for eventual howitzer emplacement. This consists of several procedures such as escorting each howitzer to its prepared position, setting up communications, providing the unit with its initial azimuth of fire, and providing each gun with an initial deflection. In the case of

550-439: Is dropped just in front of a friendly position), or in dropping fire on a recently abandoned or overrun position to prevent the enemy from consolidating there. Because the calculations have already been done, the fire can be called down very quickly when it is needed. The advance party consists of the battery commander, his driver, first sergeant, gunnery sergeant, FDC guide, gun guides, and communications representatives. Initially

600-649: Is in which position. The CPO is assisted by two "Acks"—i.e., assistants—who operate the fire data computers. The GPO (Gun Position Officer) and CPO work at the plotter to ensure that the data calculated by the Acks is accurate and safe. The CP signaller is contact with the OP, or Observation Post, where the Forward Observer Officer (FOO), works with the OP team to identify targets and call-back fire data. In recent years headset radios have become common for communication between

650-430: Is light by comparison to that of a tank, so it protects only from light fire (e.g.,  machine guns ) and shrapnel . Another disadvantage of self-propelled guns is that they tend to be equipped with lighter, less accurate guns. Depending on the nature of the battle being fought, either or both of these drawbacks could prove a severe restriction. However, this is not necessarily true of modern self-propelled guns such as

700-577: The "eyes and ears" of the respective main armies. However, despite some early success, the advent of trench warfare and aircraft observation quickly rendered this role obsolete, except to an extent in the Middle East in 1917, and in Eastern Europe where light cavalry mounted actions on a diminishing scale continued to occur until the revolution of 1917 took Russia out of the war. During the Vietnam War ,

750-640: The 17th century they were usually armed with swords , spears , javelins , or bows , and later on with sabres , pistols , shotguns , or carbines . Light cavalry was used infrequently by Ancient Greeks (who used hippeis such as prodromoi or sarissophoroi ) and Ancient Romans (who used auxiliaries such as equites Numidarum or equites Maurorum ), but were more common among the armies of Eastern Europe , North Africa , West Asia , Central Asia , and East Asia . The Arabs , Cossacks , Hungarians , Huns , Kalmycks , Mongols , Turks , Parthians , and Persians were all proficient horse archers . With

800-435: The 20th century has been the result of development of rifled cannons , improvements in propellants, better communications between observer and gunner, and technical improvements in gunnery computational abilities. Most field artillery situations require indirect fire due to weather, terrain, night-time conditions, distance, or other obstacles. These gunners can also rely upon a trained artillery observer , also called

850-431: The CPO and gun detachment commanders. The final piece of the puzzle is the firing unit itself. The FDC will transmit a warning order to the guns, followed by orders specifying the type of ammunition and fuze setting, bearing, elevation, and the method of adjustment or orders for fire for effect (FFE). Elevation (vertical direction) and bearing orders are specified in mils , and any special instructions, such as to wait for

900-504: The FA Journal began printing once again quarterly. The Magazine is currently mailed to all members of the U.S. Field Artillery Association which consist of Active Duty Army, National Guard, Marine Corps and Marine Corps Reserve, FA Re-enactors and Civilians world wide. Field artillery Until the early 20th century, field artillery were also known as foot artillery , for while the guns were pulled by beasts of burden (often horses),

950-495: The German PzH ;2000 . This has a 155 mm main armament that can with assisted firing charges reach 60 km, has a maximum speed of 67 km/h (41 mph) on road surface and 45 km/h (28 mph) off-road, and has a fully computerised fire-control system that enables it to fire-move-fire before the enemy can pin it down for counter-battery fire. It has a rate of fire of 10 rounds per minute. FDCs also exist in

1000-484: The Party looks to find suitable positions for an artillery unit to perform fire missions from. Then they perform what is known as route reconnaissance. The primary purpose of this reconnaissance is to determine the suitability of the route of the unit's movement. Items to be analyzed include possible alternate routes, cover, concealment, location of obstacles, likely ambush sites, contaminated areas, route marking requirements, and

1050-415: The U.S. Army, this entire process is covered in U.S. Army Field Manual 6-50 Chapter 2. Because artillery is an indirect fire weapon, the forward observer (FO) must take up a position where he can observe the target using tools such as binoculars and laser rangefinders and call back fire missions on his radio or telephone. The FO usually establishes a covered and concealed observation post (OP) on

1100-502: The US Army converted parts of the 1st Cavalry Division for heliborne tactics with a concept known as air cavalry . Helicopters were used to insert troops and support them. They were also used for suppression fire, search and rescue, medical evacuation, scouting and resupply. This concept was first tested at the Battle of Ia Drang Valley . Modern tactics call for the use of gunships to dominate

1150-422: The ability to observe one must attack the observation assets. Because most counter-battery radar is active, the location can be determined electronically from listening to the beams. If one suspects one's position is being observed by a covert FO then a mission, either artillery or infantry, will be raised to deal with this threat. Alternatively one can choose to make their observations obsolete by repeatedly moving

1200-439: The advance, or more dangerously, in retreat. Artillery units were particularly vulnerable to assault by light cavalry , which were frequently used in this role. Only with a number of further inventions (such as the limber , hitched to the trail of a wheeled artillery piece equipped with trunnions ), did the concept of field artillery really take off. The medieval Ming dynasty Chinese invented mobile battlefield artillery during

1250-454: The battlefield. Most of the time enemy batteries are too far away for the infantry to engage, so it falls to artillery to do this job. The battery uses a variety of techniques to calculate the position of the enemy battery, then can lay fire upon it. If possible, a FO can access a position to call fire on enemy guns directly; either on the ground or in the air, or a battery can be located using counter-battery radar , which can be used to observe

1300-425: The combatant. Thus, their role was limited to such functions as breaking sieges . Following the beginning of the gunpowder era , the first field artillery came into being as metallurgy allowed thinner cannon barrels to withstand the explosive forces without bursting. However, there was still a serious risk of the constant changes of the battlefield conspiring to leave behind slow-moving artillery units – either on

1350-472: The cost-saving measures of Base Realignment and Closure , several branch professional magazines were directed to merge. Field Artillery ceased publication with its final edition of March–April 2007. The FA Journal took a brief hiatus with publication and supported its successor as the FIRES Journal. In 2019, under new leadership from MG(R) Mark McDonald and LTG(R) David Halverson and editor, Ms. Rachal Smith,

1400-465: The curvature and rotation of the Earth . In most cases, some corrections are omitted, sacrificing accuracy for speed. In recent decades, FDCs have become computerized, allowing for much faster and more accurate computation of firing data. The FDC at the battalion level is responsible for recording friendly and enemy positions, tracking available battery munitions, and determining the optimal response for engaging

1450-566: The decline of feudalism and knighthood in Europe, light cavalry became more prominent in the armies of the continent. Many were equipped with early firearms, as their predecessors had been with bows or javelins . European examples of light cavalry included stradiots , hobelars , hussars , chasseurs à cheval , cossacks , chevau-légers , uhlans , and dragoons . Armies of the ancient Roman-Germanic wars made use of light cavalry as patrolling squads, or armed scouts , and often had them in

1500-421: The duties and responsibilities is FM 6‑30, Tactics, Techniques, and Procedures for Observed Fire . Typically, there is one FDC for a battery of six guns, in a light division. In a typical heavy division configuration, there exist two FDC elements capable of operating two four-gun sections, also known as a split battery. The FDC computes firing data—fire direction—for the guns. The process consists of determining

1550-496: The early part of the fourteenth century at the time when gunpowder and the primordial cannon were first being adopted in the West. One of the earliest documented uses of field artillery is found in the 14th-century Ming Dynasty treatise Huolongjing . The text describes a Chinese cannon called a "thousand ball thunder cannon", manufactured of bronze and fastened with wheels. The book also describes another mobile form of artillery called

1600-422: The fall of enemy shells and thus calculate their trajectory. A correctly calculated trajectory will reveal the location from which the shell was fired, which information can then be passed on to a friendly battery command post as a fire mission. To defend against counter battery fire there are two points of attack: either remove the enemy's ability to observe or make his observations irrelevant/obsolete. To remove

1650-503: The form of left/right of the bearing line and distance along it, for example "right 50 add 100" (distance in meters). When the fire is good enough the FO signals "target on, fire for effect". If the mission requires a walking barrage , he may continue sending correction orders. The FO may be called upon to direct fire for close air support and/or naval artillery in addition to field artillery based howitzer and infantry-embedded mortar units. The U.S. Army Field Manual describing

1700-589: The front lines during regional battles. During the Punic Wars, one of Carthage's main advantages over Roman armies was its extensive use of Numidian light cavalry . Partly because of this, the Roman general Scipio Africanus recruited his own cavalry from Sicily before his invasion of Tunisia during the Second Punic War . Several types of light cavalry were developed and used in medieval armies. Light cavalry played

1750-496: The ground, from which he can see the enemy. However, he may also be airborne—this was one of the first uses of aircraft in World War ;I . He must take great care not to be observed by the enemy, especially if in a static position. Discovery of an FO does not only jeopardize his personal safety; it also hampers the ability of the battery to lay fire. Using a standardized format, the FO sends map references and bearing to target,

1800-435: The gun crews would usually march on foot, thus providing fire support mainly to the infantry . This was in contrast to horse artillery , whose emphasis on speed while supporting cavalry units necessitated lighter guns and crews riding on horseback. Whereas horse artillery has been superseded by self-propelled artillery , field artillery has survived to this day both in name and mission, albeit with motor vehicles towing

1850-473: The guns (this towed artillery arrangement is often called mobile artillery ), carrying the crews and transporting the ammunition. Modern artillery has also advanced to rapidly deployable wheeled and tracked vehicles and precision delivered munitions capable of striking targets at ranges between 15 and 30 kilometers. Early artillery was unsuited to the battlefield, as the extremely massive pieces could not be moved except in areas that were already controlled by

1900-434: The guns: hence self-propelled guns . Ordinary towed guns can take a while to emplace and re-limber and are not armoured, so they are vulnerable to counter battery fire and take a while to engage when at a new location. Self-propelled guns do not suffer from these restrictions. They can drive up, drop their trails, fire and move on. Because of their armour they are less vulnerable to counter-battery fire. However, this armor

1950-520: The movement of enemy forces simply through their presence. In the aftermath of battles, light cavalry were used to press a victor's advantage or to screen retreating forces from further attack. As late as the early 1900s, most European armies still retained a nominal division of mounted troops according to the size and weight of the men, into light cavalry (raiding, reconnaissance, and screening), medium cavalry (offense or defense), and heavy cavalry (direct shock). While colonial warfare had led to

2000-524: The next higher parent battalion that "owns" two to four artillery batteries. Once again, an FDC exists at the U.S. Army brigade or USMC regimental level that "owns" the battalions. These higher level FDCs monitor the fire missions of their subordinate units and will coordinate the use of multiple batteries or even multiple battalions in what is called a battalion or brigade/regimental mission. In training and wartime exercises, as many as 72 guns from 3 battalions may all be coordinated to put "steel on

2050-399: The observer's command to fire relayed through the FDC. The crews load the howitzers and traverse and elevate the barrel to the required point, using either hand cranks (usually on towed guns) or hydraulics (on self-propelled models). Fire aimed at disabling or destroying enemy guns is known as counter-battery fire . Removing the threat posed by enemy artillery is an important objective on

2100-411: The precise target location based on the observer's location if needed, then computing range and direction to the target from the guns' location. These data can be computed manually, using special protractors and slide rules with precomputed firing data. Corrections can be added for conditions such as a difference between target and howitzer altitudes, propellant temperature, atmospheric conditions, and even

2150-420: The proposed position area, the advance party breaks contact with any enemy forces or marks minefield and hazards and moves on to find another position area. The battery commander can coordinate for additional assets, or augment the advance party with internal assets, to provide the additional ability to clear areas of small enemy forces, obstacles, and minefields. Natural cover must be used to the maximum. Security

2200-486: The specified elevation and deflection on the howitzers, punch the artillery shell followed by the bag (powder). Depending on the CFF, the gunline will fire the round when they are ready or when the FO calls and tells them to fire. The FO spots the round and sends a correction back to the FDC and the process starts all over again until it's done. The batteries are many kilometres behind the FLOT (Forward Line of Troops). They plan

2250-673: The target" in what is called a "brigade/regimental time on target" or brigade/regimental TOT for short. The rule is "silence is consent", meaning that if the lower unit does not hear a "cancel the mission" (don't shoot) or even a "check firing" (cease firing) order from the higher monitoring unit, then the mission goes on. Higher level units monitor their subordinate unit's missions both for active as well as passive purposes. Higher-level units may also get involved to coordinate artillery fire across fire support coordination boundaries (often parallel lines on maps) where one unit can not fire into without permission from higher and/or adjacent units that "own"

2300-406: The territory. Light cavalry Light cavalry comprised lightly armed and armored cavalry troops mounted on fast horses , as opposed to heavy cavalry , where the mounted riders (and sometimes the warhorses ) were heavily armored. The purpose of light cavalry was primarily raiding , reconnaissance , screening , skirmishing , patrolling , and tactical communications . Prior to

2350-431: The time and distance required to traverse the route. Several factors are taken into consideration. Once a location is determined and having arrived at the new position the advance party conducts a security sweep and prepares the position for occupation. The purpose of the advance party security with METT-T and the absence of enemy troops, mines, booby traps, NBC hazards, and so on. If these threats or conditions are present in

2400-578: The world. FA Magazine/Journal included much discussion of the military operations in both Afghanistan and Iraq and currently discusses relevant topics and articles from Active duty, National Guard, and Marines about the Modernization and Future of the Field Artillery. Articles are accepted and published based on validity of information and are references and accurate according to official DOD Doctrine unless specified as an opinion piece. The magazine

2450-576: Was first published as the Field Artillery Journal in 1911. It has gone through several name changes. Due to low subscriptions, it merged with the Infantry Journal in 1950, and was published as Combat Forces Journal ; CFJ became Army in 1954. The US Army Artillery and Missile School began the in-house publication of Tactical and Technical Trends in Artillery for Instruction in 1957 that

2500-400: Was renamed to Artillery Trends in 1958. After the Artillery branch split into the Field Artillery and Air Defense Artillery branches in 1969, the name changed to The Field Artilleryman . Field Artillery Journal restarted in 1973 as an official Field Artillery branch publication. Due to budget cuts, the magazine dropped a number of sections and was renamed Field Artillery in 1987.As part of
