A human wave attack, also known as a human sea attack, [1] is an offensive infantry tactic in which an attacker conducts an unprotected frontal assault with densely concentrated infantry formations against the enemy line, intended to overrun and overwhelm the defenders by engaging in melee combat. The name refers to the concept of a coordinated mass of soldiers falling upon an enemy force and sweeping them away with sheer weight and momentum, like an ocean wave breaking on a beach.

According to U.S. Army analyst Edward C. O'Dowd, the technical definition of a human wave attack tactic is a frontal assault by densely concentrated infantry formations against an enemy line, without any attempts to shield or to mask the attacker's movement. [2] The goal of a human wave attack is to maneuver as many people as possible into close range, hoping that the shock from a large mass of attackers engaged in melee combat would force the enemy to disintegrate or fall back. [2]
The human wave attack's reliance on melee combat usually makes the organization and the training of the attacking force irrelevant, but it requires either great physical courage, coercion, or morale for the attackers to advance into enemy fire. [3] However, when matched against modern weaponry such as automatic firearms, artillery and aircraft, a human wave attack is an extremely dangerous and costly tactic in the face of devastating firepower. [2] Thus, for a human wave attack to succeed on the modern battlefield, it is imperative for the attackers to charge into the enemy line in the shortest time and in the greatest numbers possible, so that a sufficient mass can be preserved when the attackers reach melee range. [2]
However, this solution usually means that the attackers must sacrifice concealment and cover for numbers and speed. [2] Because of this trade-off, human wave attacks can be used by an attacker which lacks tactical training or one which lacks firepower and the ability to manoeuvre, but which can motivate and control its personnel. [4]
Human wave attacks have been used by several armed forces around the world, including European and American armies during the American Civil War and World War I, [5] the Boxers during the Boxer Rebellion, the Spanish Republican Army during the Spanish Civil War, the Red Army, Imperial Japanese Army and the National Revolutionary Army during the World War II, [6] [7] The People's Volunteer Army during the Korean War and the People's Liberation Army during the Vietnam War and Sino-Vietnamese War, [8] the Iranian Basij during the Iran–Iraq War, [9] and the Russian Ground Forces during the Russian invasion of Ukraine. [10]
Human wave attacks were used during the Boxer Rebellion (1899-1901) in China. [11] Boxer rebels performed human wave attacks against Eight-Nation Alliance forces during the Seymour Expedition [12] and the Battle of Langfang [13] where the Eight Nation Alliance was forced to retreat. [14]
On June 11 and June 14 1900, Boxers armed only with bladed melee weapons directly charged the Alliance troops at Langfang armed with rifles and machine guns in human wave attacks and the Boxers also blocked the retreat of the expedition via train by destroying the Tianjin-Langfang railway. [15]
The Boxers and Dong Fuxiang's army worked together in the joint ambush with the Boxers relentlessly assaulting the Allies head on with human wave attacks displaying "no fear of death" and engaging the Allies in melee combat and putting the Allied troops under severe mental stress by mimicking vigorous gunfire with firecrackers. The Allies however suffered most of their losses at the hands of General Dong's troops, who used their expertise and persistence to engage in "bold and persistent" assaults on the Alliance forces, as remembered by the German Captain Usedom: the right wing of the Germans was almost at the point of collapse under the attack until they were rescued from Langfang by French and British troops; the Allies then retreated from Langfang in trains full of bullet holes. [16]
During the Siege of Port Arthur (1904-1905), human wave attacks were conducted on Russian artillery and machine guns by the Japanese which ended up becoming suicidal. [17] Since the Japanese suffered massive casualties in the attacks, [18] one description of the aftermath was that "a thick, unbroken mass of corpses covered the cold earth like a coverlet." [19]
Human wave attacks have also been deployed by the Republicans in Spain during the Spanish Civil War most notably their defense of Casa de Campo during the Siege of Madrid, particularly the counterattack by the Durruti Column led by Buenaventura Durruti. [20] Also, as recounted by various former members of the Lincoln Battalion, it was not uncommon for Republican commanders to order units onto attacks that were warned by field officers to be ill-advised or suicidal. [21]
There were elements of human waves being utilized in the Russian Civil War recounted by American soldiers in Russia supporting the White Army. [22]
In the Winter War of 1939–1940 the Soviet Red Army used human wave charges repeatedly against fortified Finnish positions, allowing the enemy machine gunners to mow them down, a tactic described as "incomprehensible fatalism" by the Finnish commander Mannerheim. This led to massive losses on the Soviet side and contributed to why the clearly weaker Finnish forces (both in manpower and armament) were able to temporarily resist the Soviet attacks on the Karelian Isthmus. [23] [24] Soviet attacks in other sectors were successfully halted by the Finns.
Richard Overy in his book, The Oxford History of World War II, talks about the eventual technological advancement of Soviet spearhead forces, becoming as effective as German forces, however he still acknowledges that elements of "unthinkable self-sacrifice, 'human wave' tactics, and draconian punishment" existed.
The Imperial Japanese Army was known for its use of human wave attacks. [25] [26] [27] [28] There were even specialized units who were trained in this type of assault.
The charge was used successfully in the Russo-Japanese War and the Second Sino-Japanese War, where the highly disciplined Japanese soldiers were fighting against enemies with comparatively lower discipline and without many automatic weapons such as machine guns, oftentimes outnumbering them as well. In such instances, a determined charge could break into the enemy lines and win the day. The effectiveness of such strategies in China made them a standard tactic for the Imperial Japanese Army. These tactics became mostly known to Western audiences during the Pacific War, where Japanese forces used this approach against Allied forces. However, Allied forces drastically outnumbered the Japanese, and they were equipped with a very high number of automatic weapons. They also consisted of well-trained forces who would quickly adapt to Japanese charges. If the Allied forces could establish a defensive perimeter, their superior firepower would often result in crippling Japanese casualties and a failure of the attack. The Japanese battle-cry "Banzai" led to this form of charge being called the "Banzai charge" by the Allied forces.
In addition to its strategic use by Japanese military forces, the frequency of its use has been explained, in part, as Japanese troops adhering to their traditional Bushido honor code that viewed surrender as shameful or unacceptable, whereas the bravery of a human wave charge, even if suicidal, was an honorable choice. These banzai charges by Japanese soldiers against Allied troops equipped with machine guns, light mortars, semi-automatic rifles and sub-machine guns were often ineffective in altering the outcome of a battle, but American troops later reported severe psychological pressure from defending against these out-gunned human waves.
During the Korean War, the term "human wave attack" was used to describe the Chinese short attack, a combination of infiltration and shock tactics employed by the People's Volunteer Army (PVA). [29] [30] According to some accounts, Marshal Peng Dehuai—the overall commander of the PVA forces in Korea—is said to have invented this tactic. [31]
A typical Chinese short attack was carried out at night by numerous fireteams on a narrow front against the weakest point in enemy defenses. [30] The PVA assault team would crawl undetected within grenade range, then launch surprise attacks against the defenders in order to breach the defenses by relying on maximum shock and confusion. [30] If the initial shock failed to breach the defenses, additional fireteams would press on behind them and attack the same point until a breach was created. [30] Once penetration was achieved, the bulk of the Chinese forces would move into the enemy rear and attack from behind. [32] During the attacks, the Chinese assault teams would disperse while masking themselves using the terrain, and this made it difficult for UN defenders to target numerous Chinese troops. [33] Attacks by the successive Chinese fireteams were also carefully timed to minimize casualties. [34] Due to primitive communication systems and tight political controls within the Chinese army, short attacks were often repeated indefinitely until either the defenses were penetrated or the attacker's ammunition supply were exhausted, regardless of the chances of success or the human cost. [30]
This persistent attack pattern left a strong impression on UN forces that fought in Korea, giving birth to the description of "human wave." [8] U.S. Army historian Roy Edgar Appleman observed that the term "human wave" was later used by journalists and military officials to convey the image that the American soldiers were assaulted by overwhelming numbers of Chinese on a broad front. [1] S.L.A. Marshall also commented that the word "mass" was indiscriminately used by the media to describe Chinese infantry tactics, and it is rare for the Chinese to actually use densely concentrated infantry formations to absorb enemy firepower. [35] In response to the media's stereotype of Chinese assault troops deployed in vast "human seas", a joke circulated among the US servicemen was "How many hordes are there in a Chinese platoon?" [8] [30] [36]
In Chinese sources, this tactic is referred to as "three-three fireteams," after the composition of the attack: three men would form one fireteam, and three fireteams would form one squad. A Chinese platoon, consisting of 33 to 50 soldiers (depending on if they had a heavy weapons team), would form their squads in ranks in a staggered arrowhead formation, which would be employed to attack "one point" from "two sides." [37]
Although abandoned by the PVA by 1953, [38] outside observers such as Allen S. Whiting expected China to use the tactic if necessary. [39] The Chinese army re-adopted this tactic during the Vietnam War and Sino-Vietnamese War due to the stagnation of the Chinese military modernization programs during the Cultural Revolution. [40] Their use in the Vietnam War and Sino-Vietnamese War is a rare example of an army with superior firepower, in this case the PLA, throwing away its advantage. [41]

During the Iran–Iraq War, some of the attacks conducted by Iranian forces in large operations, were considered to be human wave attacks. [42] [9]
In the Eritrean–Ethiopian War of 1998-2000, the widespread use of trenches has resulted in comparisons of the conflict to the trench warfare of World War I. [43] According to some reports, trench warfare led to the loss of "thousands of young lives in human-wave assaults on Eritrea's positions". [44] [45]
During the Russian invasion of Ukraine starting in 2022, the Ukrainian military, Western media and prominent Russian milbloggers have reported that the Russian military uses human wave attacks to overcome Ukrainian defenses. [46] [47] [48] [49] [50] [51]
During the battles of Bakhmut, Vuhledar, [47] and Avdiivka, it was claimed that Russian Army regulars were sent into the battles using human wave tactics to capture the towns. [52] [53] Wagner Group paramilitary units also used "human wave attacks" using convicts recruited from prisons to fight in Ukraine, [46] including those in the Storm-Z and Storm-V units. [52] It was also claimed that the Russian infantry sent in "human wave" attacks are poorly trained and equipped, with minimal or no mechanized or air support. [52] Rear Admiral John Kirby, spokesperson for the U.S. National Security Council, claimed that Russia threw "masses of poorly trained soldiers right into the battlefield without proper equipment, and apparently without proper training and preparation." [54] Russian troops have claimed that they were threatened with being shot by barrier troops if they retreated from attacks. [55]
The term ″meat grinder″ has been used to describe these tactics used by Russia in attempts to wear down Ukrainian forces and expose their positions to Russian artillery. [56] According to NATO and Western military officials, around 1,200 Russian soldiers were killed or wounded in Ukraine every day on average in May and June 2024, mainly due to the use of Soviet tactics and human wave attacks. These attacks have also been compared to the Imperial Japanese Army's banzai charges. [57] [58] [59]
The Battle of Chosin Reservoir, also known as the Chosin Reservoir Campaign or the Battle of Lake Changjin, was an important battle in the Korean War. The name "Chosin" is derived from the Japanese pronunciation "Chōshin", instead of the Korean pronunciation.
A bayonet is a knife, dagger, sword, or spike-shaped melee weapon designed to be mounted on the end of the barrel of a rifle, carbine, musket or similar long firearm, allowing the gun to be used as an improvised spear in close combats.
The Boxer Rebellion, also known as the Boxer Uprising or Boxer Insurrection, was an anti-foreign, anti-imperialist, and anti-Christian uprising in North China between 1899 and 1901, towards the end of the Qing dynasty, by the Society of Righteous and Harmonious Fists, known as the "Boxers" in English due to many of its members having practised Chinese martial arts, which at the time were referred to as "Chinese boxing". It was defeated by the Eight-Nation Alliance of foreign powers.
A fireteam or fire team is a small modern military subordinated element of infantry designed to optimize "NCO initiative", "combined arms", "bounding overwatch" and "fire and movement" tactical doctrine in combat. Depending on mission requirements, a typical "standard" fireteam consists of four or fewer members: an automatic rifleman, a grenadier, a rifleman, and a designated fireteam leader. The role of each fireteam leader is to ensure that the fireteam operates as a cohesive unit. Two or three fireteams are organized into a section or squad in co-ordinated operations, which is led by a squad leader.
A charge is an offensive maneuver in battle in which combatants advance towards their enemy at their best speed in an attempt to engage in a decisive close combat. The charge is the dominant shock attack and has been the key tactic and decisive moment of many battles throughout history. Modern charges usually involve small groups of fireteams equipped with weapons with a high rate of fire and striking against individual defensive positions, instead of large groups of combatants charging another group or a fortified line.
In warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy frontline strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options.
A pocket is a group of combat forces that have been isolated by opposing forces from their logistical base and other friendly forces. In mobile warfare, such as blitzkrieg, salients were more likely to be cut off into pockets, which became the focus of battles of annihilation.
The Battle of Inchon, also spelled Battle of Incheon, was an amphibious invasion and a battle of the Korean War that resulted in a decisive victory and strategic reversal in favor of the United Nations Command (UN). The operation involved some 75,000 troops and 261 naval vessels and led to the recapture of the South Korean capital of Seoul two weeks later. The code name for the Inchon operation was Operation Chromite.
The People's Volunteer Army (PVA), officially the Chinese People's Volunteers (CPV), was the armed expeditionary forces deployed by the People's Republic of China during the Korean War. Although all units in the PVA were actually transferred from the People's Liberation Army (PLA) under the orders of Chairman Mao Zedong, the PVA was separately constituted in order to prevent an official war with the United States. The PVA entered Korea on 19 October 1950 and completely withdrew by October 1958. The nominal commander and political commissar of the PVA was Peng Dehuai before the ceasefire agreement in 1953, although both Chen Geng and Deng Hua served as the acting commander and commissar after April 1952 following Peng's illness. The initial units in the PVA included 38th, 39th, 40th, 42nd, 50th, 66th Corps; totalling 250,000 men. About 3 million Chinese civilian and military personnel had served in Korea throughout the war.
Banzai charge or Banzai attack is the term that was used by the Allied forces of World War II to refer to Japanese human wave attacks and swarming staged by infantry units. This term came from the Japanese battle cry tennōheika banzai, and was shortened to banzai, specifically referring to the tactic used by the Imperial Japanese Army during the Pacific War. This tactic was used when the Japanese commanders of infantry battalions foresaw that a battle was about to be lost, as a last ditch effort in thwarting Allied forces.
A military column is a formation of soldiers marching together in one or more files in which the file is significantly longer than the width of ranks in the formation. The column formation allows the unit rapid movement and a very effective charge, and it can quickly form square to resist cavalry attacks, but by its nature only a fraction of its muskets are able to open fire.
Tank desant is a military combined arms tactic where infantry soldiers ride into an attack on tanks, then dismount to fight on foot in the final phase of the assault. Note that this differs from infantry troops merely riding on tanks as a form of ad-hoc transportation. Desant is a pan-Slavic general term for airborne forces and amphibious warfare.
The Regimental Combat Team 31 (RCT-31), commonly referred to as Task Force Faith of the "Chosin Few", is a United States Army unit known for its role in the Battle of Chosin Reservoir during the Korean War where 90-95% of its force was killed, wounded, and/or captured on the eastern side of the reservoir.
The Battle of the Pusan Perimeter, known in Korean as the Battle of the Naktong River Defense Line, was a large-scale battle between United Nations Command (UN) and North Korean forces lasting from August 4 to September 18, 1950. It was one of the first major engagements of the Korean War. An army of 140,000 UN troops, having been pushed south to the brink of defeat, were rallied to make a final stand against the invading Korean People's Army (KPA), 98,000 men strong.
Tunnel warfare is using tunnels and other underground cavities in war. It often includes the construction of underground facilities in order to attack or defend, and the use of existing natural caves and artificial underground facilities for military purposes. Tunnels can be used to undermine fortifications and slip into enemy territory for a surprise attack, while it can strengthen a defense by creating the possibility of ambush, counterattack and the ability to transfer troops from one portion of the battleground to another unseen and protected. Also, tunnels can serve as shelter from enemy attack.
The Battle of the Notch was an engagement between United States and North Korean forces early in the Korean War on August 2, 1950, in southern South Korea. The fight ended in a victory for the United States after North Korean forces attempting to assault the US position were blocked and repelled repeatedly, suffering heavy casualties.
The Hill 303 massacre was a war crime that took place during the opening days of the Korean War on August 17, 1950, on a hill above Waegwan, Republic of Korea. Forty-one United States Army (US) prisoners of war were murdered by troops of the North Korean People's Army (KPA) during one of the engagements of the Battle of Pusan Perimeter.
The Battle of Langfang took place during the Seymour Expedition during the Boxer Rebellion, in June 1900, involving Chinese imperial troops, the Chinese Muslim Kansu Braves and Boxers ambushing and defeating the Eight-Nation Alliance expeditionary army on its way to Beijing, pushing the Alliance forces to retreat back to Tientsin (Tianjin).
The Battle of Đồng Đăng was the initial phase of the Battle of Lạng Sơn during the Sino–Vietnamese War, taking place in the town of Đồng Đăng and nearby positions between 17–23 February 1979.
The Battle of Lạng Sơn was fought during the 1979 Sino-Vietnamese War, days after the Chinese People's Liberation Army (PLA) advanced 15 to 20 kilometres deep into the northern provinces of Vietnam. The fighting occurred primarily at the city of Lạng Sơn, a few kilometres from the Sino-Vietnamese border.
