Loss exchange ratio is a figure of merit in attrition warfare, and is generally defined as the ratio of the losses (e.g., casualties) sustained by each side in a conflict. It is usually relevant to a condition or state of war where one side depletes the resources of another through attrition. Specifically and most often used as a comparator in aerial combat, where it is known as a kill-ratio.
Loss exchange ratio has played a significant role in past wars, especially those that have devolved into stalemate and become wars of attrition. For example, the German objective at the Battle of Verdun (1916) during World War I was not the seizure of any strategic objective, but rather to inflict an LER of 2:1 on the French forces and thereby cripple the French army.[ dubious – discuss ]
During the First Indochina War, Võ Nguyên Giáp, the leader of the Việt Minh, told his French opposite number that "you can kill ten of my men for every one I kill of yours, and at that rate, I will still triumph." In fact, the LER was approximately 3:1 in favor of the French, and they did indeed withdraw in defeat. A total of 500,000+ Vietnamese were either killed, wounded or captured during the First Indochina War. [1]

It is arguable that the concept of the Loss exchange ratio has become relatively less important in modern Western military doctrine, as some military theories[ who? ] posit that it is just as militarily effective to disrupt enemy forces and outmaneuver them, thereby reducing their combat effectiveness without necessarily inflicting massive casualties.
A battle is an occurrence of combat in warfare between opposing military units of any number or size. A war usually consists of multiple battles. In general, a battle is a military engagement that is well defined in duration, area, and force commitment. An engagement with only limited commitment between the forces and without decisive results is sometimes called a skirmish.
The Battle of the Somme, also known as the Somme offensive, was a major battle of the First World War fought by the armies of the British Empire and the French Third Republic against the German Empire. It took place between 1 July and 18 November 1916 on both sides of the upper reaches of the river Somme in France. The battle was intended to hasten a victory for the Allies. More than three million men fought in the battle, of whom more than one million were either wounded or killed, making it one of the deadliest battles in all of human history.
The Tet Offensive was a major escalation and one of the largest military campaigns of the Vietnam War. The Viet Cong (VC) and North Vietnamese People's Army of Vietnam (PAVN) launched a surprise attack on 30 January 1968 against the forces of the South Vietnamese Army of the Republic of Vietnam (ARVN), the United States Armed Forces and their allies. It was a campaign of surprise attacks against military and civilian command and control centers throughout South Vietnam. The name is the truncated version of the Lunar New Year festival name in Vietnamese, Tết Nguyên Đán, with the offense chosen during a holiday period as most ARVN personnel were on leave. The purpose of the wide-scale offensive by the Hanoi Politburo was to trigger political instability in a belief that mass armed assault on urban centers would trigger defections and rebellions.
Attrition warfare is a military strategy consisting of belligerent attempts to win a war by wearing down the enemy to the point of collapse through continuous losses in personnel, materiel and morale. The word attrition comes from the Latin root atterere, meaning "to rub against", similar to the "grinding down" of the opponent's forces in attrition warfare.
Lanchester's laws are mathematical formulas for calculating the relative strengths of military forces. The Lanchester equations are differential equations describing the time dependence of two armies' strengths A and B as a function of time, with the function depending only on A and B.
A body count is the total number of people killed in a particular event. In combat, a body count is often based on the number of confirmed kills, but occasionally only an estimate. Often used in reference to military combat, the term can also refer to any situation involving multiple killings, such as the actions of death squads or serial killers.
Maneuver warfare, or manoeuvre warfare, is a military strategy which emphasizes movement, initiative and surprise to achieve a position of advantage. Maneuver seeks to inflict losses indirectly by envelopment, encirclement and disruption, while minimizing the need to engage in frontal combat. In contrast to attrition warfare where strength tends to be applied against strength, maneuver warfare attempts to apply strength against weakness in order to accomplish the mission.
Estimates of casualties of the Vietnam War vary widely. Estimates can include both civilian and military deaths in North and South Vietnam, Laos, and Cambodia.
Force concentration is the practice of concentrating a military force so as to bring to bear such overwhelming force against a portion of an enemy force that the disparity between the two forces alone acts as a force multiplier in favour of the concentrated forces.
The Battle of Hòa Bình was fought during the First Indochina War. It occurred from 10 November 1951 to 25 February 1952, when French Union forces attempted to lure the Việt Minh out into the open and to force it to fight on French terms.
During the Vietnam War, the National Liberation Front of South Vietnam (NLF), and the People's Army of Vietnam (PAVN), used a distinctive land warfare strategy to defeat their South Vietnamese Army of the Republic of Vietnam (ARVN) and American opponents. These methods involved closely integrated political and military strategy – what was called dau tranh – literally "to struggle".
Operation Camargue was one of the largest operations by the French Far East Expeditionary Corps and Vietnamese National Army in the First Indochina War. It took place from 28 July until 10 August 1953. French armored platoons, airborne units and troops delivered by landing craft to the coast of central Annam, modern-day Vietnam, attempted to sweep forces of the communist Viet Minh from the critical Route 1.
VC and PAVN battle tactics comprised a flexible mix of guerrilla and conventional warfare battle tactics used by Viet Cong (VC) and the North Vietnamese People's Army of Vietnam (PAVN) to defeat their U.S. and South Vietnamese (GVN/ARVN) opponents during the Vietnam War.
The Cochinchina campaign was a series of military operations between 1858 and 1862, launched by a joint naval expedition force on behalf of the French Empire and the Kingdom of Spain against the Nguyễn period Vietnamese state. It was the opening conflict of the French conquest of Vietnam.
The Sino-Vietnamese conflicts of 1979–1991 were a series of border and naval clashes between the People's Republic of China and the Socialist Republic of Vietnam following the Sino-Vietnamese War in 1979. These clashes lasted from the end of the Sino-Vietnamese War until the normalization of ties in 1991.
In armed conflicts, the civilian casualty ratio is the ratio of civilian casualties to combatant casualties, or total casualties. The measurement can apply either to casualties inflicted by or to a particular belligerent, casualties inflicted in one aspect or arena of a conflict or to casualties in the conflict as a whole. Casualties usually refer to both dead and injured. In some calculations, deaths resulting from famine and epidemics are included.
The Battle of Lào Cai was fought between Chinese and Vietnamese forces during the Sino-Vietnamese War. Though the Chinese sustained heavy losses in fighting, they were successful in capturing and occupying the city of Lào Cai and the surrounding towns.
Operation Crazy Horse, named after Lakota warrior Crazy Horse, was a search and destroy mission during the Vietnam War conducted by military forces of the United States, South Vietnam, and the Republic of South Korea in two valleys in Bình Định Province of South Vietnam.
The Vietnam War body count controversy centers on the counting of enemy dead by the United States Armed Forces during the Vietnam War (1955–1975). There are issues around killing and counting unarmed civilians (non-combatants) as enemy combatants, as well as inflating the number of actual enemy who were killed in action (KIA). For search and destroy operations, as the objective was not to hold territory or secure populations, victory was assessed by having a higher enemy body count.
