Harassing fire is a form of psychological warfare in which an enemy force is subjected to random, unpredictable and intermittent small-arms or artillery fire over an extended period of time (usually at night and times of low conflict intensity) in an effort to undermine morale, increase the enemy's stress levels and deny them the opportunity for sleep, rest and resupply. This lowers the enemy's overall readiness and fighting ability, acting as a force multiplier for the harassing force. [1]

Contents

As the name suggests, harassing fire is undertaken as an extreme form of nuisance without a major effort to produce significant casualties or to support a larger attack. The intent is to merely ensure the enemy can never fully rest or attend to non-combat related tasks and must always be alert and in cover from incoming fire. For this reason, harassing fire is often conducted at night (or around the clock if resources allow) and by a small number of guns or artillery pieces rather than the whole contingent. The denial of sleep and constant alert state it induces is physically and psychologically unsustainable by infantry forces for any length of time, and eventually causes severe degenerative stress and degradation of the force's combat abilities. For this reason, it has been a standard and efficacious tactic used since the introduction of the projectile weapon.

History

Antiquity

Harassing fire became commonplace after the invention of the catapult and trebuchet, which could be used to hurl a variety of harmful objects over fortified walls during the siege of a city or castle. Since such a siege could drag on for months or years if the attackers were unable to forcibly breach the walls, an alternative plan called for patience coupled with regular harassing fire in an effort to induce the defenders to surrender due to low morale, disease, and starvation. Aside from lethal projectiles such as stones and iron balls, the artillery of the time would also throw harassment projectiles: rotting bodies (both men and animals), plague-infected corpses, piles of human excrement, beehives and the severed heads of captured enemy prisoners of war, all in an effort to harass and discourage the besieged defenders until they surrendered.

World War I

Harassing fire entered a new phase following the widespread mass-production of cheap, long-range high-explosive artillery in World War I, assisted by the static, inflexible nature of the defensive positions faced. Whole batteries on all sides of the conflict were dedicated to harassing fire (especially prior to a planned infantry attack) and the concept was refined to a science, complete with formulae for shells-per-hour and pattern density to ensure sleep and resupply were statistically impossible for the targeted force. In most cases, resupply and relief was already nearly impossible during the day due to artillery observers, and the addition of random harassing fire at night meant even fewer replacements and supplies could reach the front. The shell shock this eventually induced in the enemy was usually a dissociative psychological reaction to months of unending explosions, fear, hunger and sleep deprivation.

World War II

Harassing fire continued to be an effective and widespread practice in World War II as bomber aircraft and missiles were added to the equation. Soviet forces famously formed three all-female military aviation regiments in 1942 (the 586th, 587th and 588th), with the 588th Regiment exclusively equipped for night harassment raids with obsolescent Polikarpov Po-2 biplane trainer aircraft. Although very slow, poorly armed and virtually defenseless during the day, the nearly all-wood structure Po-2 was exceptionally cheap and reliable, could carry six small, 50 kg (110 lb), HE bombs and was nearly silent when flown by an expert at night; its small, low-RPM five-cylinder radial piston engine produced only a muted rattling for a sound signature, far quieter and less identifiable than the supercharged aero-engines of a then-modern fighter/bomber. As a result, it was much harder to pinpoint the plane's exact bearing or distance and gave the target very little warning of their arrival.

Although initially sneered at by the Germans, who called the Po-2 Russenfurnier ("Russian plywood") or Die Nähmaschine ("the sewing machine"), it proved unexpectedly effective at night harassment attacks on rear areas of the German lines, flying so low and slow the German fighters were unable to locate or engage them. The otherwise obsolescent-for-combat wood-and-fabric plane also proved both highly resistant to standard armor-piercing anti-aircraft ammunition, as well as invisible to modern radar, leaving the Germans with no option but blind saturation flak and searchlights, neither of which were particularly successful and helped further ensure nobody in an encampment could get any restful sleep. Soon the Germans frustratedly dubbed the women pilots Die Nachthexen, "The Night Witches", and Luftwaffe pilots and anti-aircraft gunners were promised the Iron Cross if they managed to shoot down even a single Po-2. The Germans themselves began using their own obsolescent aircraft for similar raids against the Soviets, first with the Störkampfstaffel-named squadron-size units, then banding those together into Nachtschlachtgruppe units for this purpose.

Early in the Pacific Theater of World War II during the Guadalcanal campaign, American forces defending Henderson Field from the Japanese were periodically harassed by a small number of Japanese military aircraft on night harassment raids, with their engine(s) deliberately adjusted to run in a manner that would awake American troops at night.

Harassing fire also expanded to civilians as terror bombing of cities became the norm. In a 1944 report on the recent introduction of the V-1 Flying Bomb, Time magazine referred to the attacks on London as a form of harassing fire, since they were random and frightening attacks (usually at night) designed to damage English civilian morale rather than directly disable members of the British military. A tired, frightened worker would produce less war material at their daily factory jobs, they opined. [2]

During the Korean War, the Po-2 was once again used for "Bedcheck Charlie" night harassment attacks, this time by the North Korean People's Air Force against the UN forces defending South Korea – successful raids by the KPAF on UN air bases even managed to destroy small numbers of F-51 Mustang and F-86 Sabre fighters early in the war.

Modern day

The concept continues to be relevant in modern warfare and remains in the artillery curriculum of the US Army War College [5] and the US Army's War Plans Division. [6]

Artillery Long-ranged guns for land warfare

Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. 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 generally providing the largest share of an army's total firepower.

Strategic bombing Systematic aerial attacks to destroy infrastructure and morale

Strategic bombing is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematically organized and executed attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability. If the targets are civilian without a military value, in order to effect on the enemy morale, a term terror bombing is used.

The Blitz German bombing of Britain during WWII

The Blitz was a German bombing campaign against the United Kingdom in 1940 and 1941, during the Second World War. The term was first used by the British press and originated from the term Blitzkrieg, the German word for 'lightning war'.

Attack aircraft Tactical military aircraft that have a primary role of attacking targets on land or at sea

An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.

Trench warfare Land warfare involving static fortification of lines

Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.

Incendiary device Weapons intended to start fires

Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires or destroy sensitive equipment using fire, that use materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often known as bombs, they are not explosives but in fact are designed to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm for example, is petroleum especially thickened with certain chemicals into a 'gel' to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression.

Anti-tank warfare Technology and tactics based around countering and immobolizing tanks

Anti-tank warfare originated from the need to develop technology and tactics to destroy tanks during World War I. Since the Triple Entente developed the first tanks in 1916 but did not deploy them in battle until 1917, the German Empire developed the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, as well as ground-attack aircraft.

Technology during World War I Technology available in World War I

Technology during World War I (1914–1918) reflected a trend toward industrialism and the application of mass-production methods to weapons and to the technology of warfare in general. This trend began at least fifty years prior to World War I during the American Civil War of 1861–1865, and continued through many smaller conflicts in which soldiers and strategists tested new weapons.

Suppressive fire Weapons fire that degrades the performance of an enemy force

In military science, suppressive fire is "fire that degrades the performance of an enemy force below the level needed to fulfill its mission". When used to protect exposed friendly troops advancing on the battlefield, it is commonly called covering fire. Suppression is usually only effective for the duration of the fire. It is one of three types of fire support, which is defined by NATO as "the application of fire, coordinated with the maneuver of forces, to destroy, neutralise or suppress the enemy".

Aviation in World War I Use of aircraft during the First World War

World War I was the first major conflict involving the large-scale use of aircraft. Tethered observation balloons had already been employed in several wars, and would be used extensively for artillery spotting. Germany employed Zeppelins for reconnaissance over the North Sea and Baltic and also for strategic bombing raids over Britain and the Eastern Front.

Bombing of Warsaw in World War II

The bombing of Warsaw in World War II started with the aerial bombing campaign of Warsaw by the German Luftwaffe during the siege of Warsaw in the invasion of Poland in 1939. It also included German bombing raids during the Warsaw Uprising in 1944. During the course of the war, approximately 85% of the city was destroyed due to German mass bombings, heavy artillery fire, and a planned demolition campaign.

Polikarpov Po-2 All-weather multirole Soviet biplane

The Polikarpov Po-2 served as an all-weather multirole Soviet biplane, nicknamed Kukuruznik (Russian: Кукурузник, NATO reporting name "Mule". The reliable, uncomplicated design of the Po-2 design made it an ideal trainer aircraft, as well as doubling as a low-cost ground attack, aerial reconnaissance, psychological warfare and liaison aircraft during war, proving to be one of the most versatile light combat types to be built in the Soviet Union. As of 1978 it remained in production for a longer period of time than any other Soviet-era aircraft.

Industrial warfare Impact of the Industrial Age on warfare

Industrial warfare is a period in the history of warfare ranging roughly from the early 19th century and the start of the Industrial Revolution to the beginning of the Atomic Age, which saw the rise of nation-states, capable of creating and equipping large armies, navies, and air forces, through the process of industrialization.

Rocket artillery Class of rockets used as artillery

Rocket artillery is artillery that uses rocket explosives as the projectile. The use of rocket artillery dates back to medieval China where devices such as fire arrows were used. Fire arrows were also used in multiple launch systems and transported via carts. First true rocket artillery was developed in India by the Kingdom of Mysore. In the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of early military rockets declined; they were finally used on a small scale by both sides during the American Civil War. Modern rocket artillery was first employed during World War II, in the form of the German Nebelwerfer family of rocket ordnance designs, Soviet Katyusha-series and numerous other systems employed on a smaller scale by the Western allies and Japan. In modern use, the rockets are often guided by an internal guiding system or GPS in order to maintain accuracy.

Battle of Los Angeles Anti-aircraft shelling during WWII in Los Angeles, CA, against an imagined attack

The Battle of Los Angeles, also known as the Great Los Angeles Air Raid, is the name given by contemporary sources to a rumored attack on the continental United States by Imperial Japan and the subsequent anti-aircraft artillery barrage which took place from late 24 February to early 25 February 1942, over Los Angeles, California. The incident occurred less than three months after the U.S. entered World War II in response to the Imperial Japanese Navy's surprise attack on Pearl Harbor, and one day after the bombardment of Ellwood near Santa Barbara on 23 February. Initially, the target of the aerial barrage was thought to be an attacking force from Japan, but speaking at a press conference shortly afterward, Secretary of the Navy Frank Knox called the purported attack a "false alarm". Newspapers of the time published a number of reports and speculations of a cover-up to conceal an actual invasion by enemy airplanes.

The Battle of A Shau was waged in early 1966 during the Vietnam War between the People's Army of Vietnam (PAVN) and the forces of the United States and South Vietnam. The battle began on March 9 and lasted until March 10 with the fall of the U.S. Army's Special Forces camp of the same name. The battle was a strategic victory for the PAVN in that they were able to take control of the A Shau Valley and use it as a base area for the rest of the war.

Air Resupply And Communications Service Military unit

The Air Resupply And Communications Service (ARCS) is an inactive United States Air Force organization. It was assigned to Andrews Air Force Base, Maryland. Established during the Korean War, the mission of ARCS was providing the Air Force an unconventional warfare capability during the 1950s. It was inactivated in 1954, but elements continued to operate until the reactivation of air commando units by the Kennedy Administration in 1962.

Battles of the Kinarot Valley Part of the 1948 Arab–Israeli War

The Battles of the Kinarot Valley, is a collective name for a series of military engagements between the Haganah and the Syrian army during the 1948 Arab–Israeli War, fought between 15–22 May 1948 in the Kinarot Valley. It includes two main sites: the Battle of Degania–Samakh (Tzemah), and battles near Masada–Sha'ar HaGolan. The engagements were part of the battles of the Jordan Valley, which also saw fighting against Transjordan in the area of Gesher.

Operation Miracle (Rhodesia)

Operation Miracle or the Battle of Mavonde was a military raid in 1979 by the Rhodesian Security Forces (RSF) against ZANLA guerrilla bases in Mozambique towards the end of the Rhodesian Bush War. ZANLA put up stiff resistance and the tactical success of the RSF did not lead to the expected strategic changes.

Battle for Outpost Vegas

The battle for Outpost Vegas was a battle during the Korean War between the armed forces of the United Nations Command (UN) and China from 26 to 30 March 1953, four months before the end of the Korean War. Vegas was one of three outposts called the Nevada Cities north of the Main Line of Resistance (MLR), the United Nations defensive line which stretched roughly around the latitude 38th Parallel. Vegas, and the outposts it supported, Reno and Carson, were manned by elements of the 1st Marine Division. On 26 March 1953 the Chinese People's Volunteer Army (PVA) launched an attack on the Nevada Cities, including Vegas, in an attempt to better the position of China and North Korea in the Panmunjon peace talks which were occurring at the time, and to gain more territory for North Korea when its borders would be solidified. The battle raged for five days until PVA forces halted their advance after capturing one outpost north of the MLR on 30 March, but were repelled from Vegas. The battle for Outpost Vegas and the surrounding outposts are considered the bloodiest fighting to date in western Korea during the Korean War. It is estimated that there were over 1,000 American casualties and twice that number of Chinese during the Battle for Outpost Vegas. The battle is also known for the involvement of Sergeant Reckless, a horse in a USMC recoilless rifle platoon who transported ammunition and the wounded during the U.S. defense of outpost Vegas.
