For example, after the US suspended conscription in 1973, "the military disproportionately attracted African American men, men from lower-status socioeconomic backgrounds, men who had been in nonacademic high school programs, and men whose high school grades tended to be low". However, a study released in 2020 on the socio-economic backgrounds of U.S. Armed Forces personnel suggests that they are at parity or slightly higher than

In adolescents who misuse alcohol, neurological and psychological dysfunctions may contribute to the increased risk of suicide. Overdose attempts using painkillers are among
1290-644: A hard time readjusting to society, primarily because of the uniquely divisive nature of the Vietnam War in the context of U.S. history . That social division has expressed itself by the lack both of public and institutional support for the former servicemen that would be expected by returning combatants of most conflicts in most nations. In a material sense also, veterans benefits for Vietnam-era veterans were dramatically less than those enjoyed after World War II .

The documentary In the Shadow of the Blade (released in 2004) reunited Vietnam veterans and families of the war dead with a restored UH-1 "Huey" helicopter in a cross-country journey to tell
9030-513: The civilian population with respect to socio-economic indicators such as parental income, parental wealth and cognitive abilities. The study found that technological, tactical, operational and doctrinal changes have led to a change in the demand for personnel. Furthermore, the study suggests that the most disadvantaged socio-economic groups are less likely to meet the requirements of the modern U.S. military. The obligations of military employment are many. Full-time military employment normally requires
9159-587: The commanding forces and other military, as well as often civilian personnel participate in identification of these threats. This is at once an organization, a system and a process collectively called military intelligence (MI). Areas of study in Military intelligence may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. The difficulty in using military intelligence concepts and military intelligence methods
9288-454: The concepts and methods used by the command to employ appropriately military skilled, armed and equipped personnel in achievement of the tangible goals and objectives of the war , campaign , battle , engagement, and action. The line between strategy and tactics is not easily blurred, although deciding which is being discussed had sometimes been a matter of personal judgement by some commentators, and military historians. The use of forces at
9417-410: The concerns of military command. Military strategy is more concerned with the supply of war and planning, than management of field forces and combat between them. The scope of strategic military planning can span weeks, but is more often months or even years. Operational mobility is, within warfare and military doctrine , the level of command which coordinates the minute details of tactics with
9546-512: The consumables, and capital equipment of the troops. Although mostly concerned with the military transport , as a means of delivery using different modes of transport; from military trucks , to container ships operating from permanent military base , it also involves creating field supply dumps at the rear of the combat zone, and even forward supply points in a specific unit's tactical area of responsibility . These supply points are also used to provide military engineering services, such as
9675-410: The consumption of drugs and their effects on the human body encompasses all aspects of sex, including desire , performance , pleasure , conception , gestation , and disease . There are many different types of drugs that are commonly associated with their effects on sex, including alcohol , cannabis , cocaine , MDMA , GHB , amphetamines , opioids , antidepressants , and many others. In
9804-595: The country for Western countries including the United States and Australia , either by or through the Humanitarian Operation (HO). According to the U.S. Department of Labor , the Vietnam Era Veterans' Readjustment Assistance Act of 1974 ( VEVRAA ) states, "A Vietnam era veteran" is a person who: In 2004, the U.S. Census Bureau reported there were 8.2 million Vietnam-era veterans who were living in
9933-550: The cracks in our prison cell. But there are not many drugs which have the power of stilling such craving. The entire catalog, at least to the extent that research has thus far written it, may include only opium, hashish, and in rarer cases alcohol , which has enlightening effects only upon very particular characters. During the 20th century, the majority of countries initially responded to the use of recreational drugs by prohibiting production, distribution, or use through criminalization. A notable example occurred with Prohibition in
10062-429: The demands of military life, including preparedness to injure and kill other people, and to face mortal danger without fleeing. It is a physically and psychologically intensive process which resocializes recruits for the unique nature of military demands. For example: The next requirement comes as a fairly basic need for the military to identify possible threats it may be called upon to face. For this purpose, some of
10191-474: The dose and frequency of administering the drug. In the period 1966–1969, the U.S. military provided 225 million tablets of stimulants, mostly dextroamphetamine, according to a 1971 report by the Select Committee on Crime of the U.S. House of Representatives . According to a member of a long-range reconnaissance platoon, the drugs "gave you a sense of bravado as well as keeping you awake. Every sight and sound
10320-407: The drive to alter one's state of mind is universal. In The Hasheesh Eater (1857), American author Fitz Hugh Ludlow was one of the first to describe in modern terms the desire to change one's consciousness through drug use: [D]rugs are able to bring humans into the neighborhood of divine experience and can thus carry us up from our personal fate and the everyday circumstances of our life into
10449-460: The end of war'. According to Clausewitz: strategy forms the plan of the War, and to this end it links together the series of acts which are to lead to the final decision, that is to say, it makes the plans for the separate campaigns and regulates the combats to be fought in each. Hence, Clausewitz placed political aims above military goals , ensuring civilian control of the military . Military strategy
10578-464: The enzyme cyclooxygenase . General anesthetics are a class of psychoactive drug used on people to block physical pain and other sensations. Most anesthetics induce unconsciousness , allowing the person to undergo medical procedures like surgery , without the feelings of physical pain or emotional trauma . To induce unconsciousness, anesthetics affect the GABA and NMDA systems. For example, Propofol
10707-401: The existence of the military is to engage in combat , should it be required to do so by the national defence policy, and to win. This represents an organisational goal of any military, and the primary focus for military thought through military history . How victory is achieved, and what shape it assumes, is studied by most, if not all, military groups on three levels. Military strategy is
10836-446: The first "pharmacological war" in history, the U.S. war in Vietnam was so called because of the unprecedented level of psychoactive drugs that U.S. servicemen used. The U.S. military had routinely provided heavy psychoactive drugs, including amphetamines , to American servicemen, which left them unable to process adequately their war traumas at the time. The U.S. armed forces readily distributed large amounts of "speed" ( stimulants ), in
10965-559: The first Vietnam veteran to be a regular character in a U.S. dramatic series was Lincoln Case on Route 66 . Case, played by Glenn Corbett, was introduced in 1963, long before the major U.S. buildup in Vietnam. "Linc" Case was initially portrayed as an angry, embittered man, not only because of his harrowing wartime experiences (which included being taken prisoner and escaping a POW camp) but also because of his grim childhood and continuing estrangement from much of his family. The show depicted his effort to make peace with himself and others. In
11094-453: The first local organizations by and for Vietnam veterans in 1981, now known as Veterans Village. Vets were also largely responsible for taking debriefing and treatment strategies into the larger community where they were adapted for use in conjunction with populations impacted by violent crime, abuse, and man-made and natural disasters and those in law enforcement and emergency response. Other notable organizations that were founded then included
11223-481: The form of Dexedrine ( dextroamphetamine ), an amphetamine twice as strong as Benzedrine, to American servicemen. Soldiers embarking on long-range reconnaissance missions or ambushes, according to standard military instruction, were supposed to be given 20 milligrams of dextroamphetamine for 48 hours of combat readiness. But this instruction for heavy drugs was rarely followed: the drug was issued, according to veterans, "like candies," with little or no attention paid to
11352-776: The form of military camouflage or misdirection using decoys , is used to confuse the enemy as a tactic. A major development in infantry tactics came with the increased use of trench warfare in the 19th and 20th centuries. This was mainly employed in World War I in the Gallipoli campaign , and the Western Front . Trench warfare often turned to a stalemate, only broken by a large loss of life, because, in order to attack an enemy entrenchment, soldiers had to run through an exposed ' no man's land ' under heavy fire from their opposing entrenched enemy. As with any occupation, since ancient times,
11481-513: The largest armed forces in the World" or that "the U.S. Military is considered to be the world's strongest". Although some groups engaged in combat, such as militants or resistance movements , refer to themselves using military terminology, notably 'Army' or 'Front', none have had the structure of a national military to justify the reference, and usually have had to rely on support of outside national militaries. They also use these terms to conceal from
11610-525: The late 17th century. Perhaps its most enduring maxim is Igitur qui desiderat pacem, praeparet bellum (let he who desires peace prepare for war). Due to the changing nature of combat with the introduction of artillery in the European Middle Ages , and infantry firearms in the Renaissance , attempts were made to define and identify those strategies, grand tactics , and tactics that would produce
11739-784: The length of properly followed treatment regimens (that is, relapse rate substantially declines over time), and to a much greater degree than placebo. Militaries worldwide have used or are using various psychoactive drugs to treat pain and to improve performance of soldiers by suppressing hunger, increasing the ability to sustain effort without food, increasing and lengthening wakefulness and concentration, suppressing fear , reducing empathy, and improving reflexes and memory-recall among other things. Both military and civilian American intelligence officials are known to have used psychoactive drugs while interrogating captives apprehended in its " war on terror " . In July 2012 Jason Leopold and Jeffrey Kaye , psychologists and human rights workers, had
11868-482: The level of organization between strategic and tactical is called operational mobility . Because most of the concepts and methods used by the military, and many of its systems are not found in commercial branches, much of the material is researched, designed, developed, and offered for inclusion in arsenals by military science organizations within the overall structure of the military. Therefore, military scientists can be found interacting with all Arms and Services of
11997-426: The management of forces in wars and military campaigns by a commander-in-chief , employing large military forces, either national and allied as a whole, or the component elements of armies , navies and air forces ; such as army groups , naval fleets , and large numbers of aircraft .

12126-630: The manufacturers who would produce these in adequate quantity and quality for their use in combat; purchase the concepts, methods, and systems; create a forces structure that would use the concepts, methods, and systems most effectively and efficiently; integrate these concepts, methods, and systems into the force structure by providing military education , training , and practice that preferably resembles combat environment of intended use; create military logistics systems to allow continued and uninterrupted performance of military organizations under combat conditions, including provision of health services to
12255-497: The military has been distinguished from other members of the society by their tools: the weapons and military equipment used in combat. When Stone Age humans first took flint to tip the spear , it was the first example of applying technology to improve the weapon. Since then, the advances made by human societies, and that of weapons, has been closely linked. Stone weapons gave way to Bronze Age and Iron Age weapons such as swords and shields . With each technological change
12384-436: The military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control , promotion of political agendas , emergency services and reconstruction, protecting corporate economic interests, social ceremonies, and national honour guards . The profession of soldiering is older than recorded history . Some images of classical antiquity portray
12513-405: The more common usage distinguishes between those who served "in-country" and those who did not serve in Vietnam by referring to the "in-country" veterans as "Vietnam veterans" and the others as "Vietnam-era veterans." Regardless, the U.S. government officially refers to all as "Vietnam-era veterans." In the United States , the term "Vietnam veteran" is not typically used in relation to members of
12642-873: The most common, due to their easy availability over-the-counter. Psychoactive drugs are administered via oral ingestion as a tablet, capsule, powder, liquid, and beverage; via injection by subcutaneous , intramuscular , and intravenous route; via rectum by suppository and enema ; and via inhalation by smoking , vaporizing , and snorting. The efficiency of each method of administration varies from drug to drug. The psychiatric drugs fluoxetine , quetiapine , and lorazepam are ingested orally in tablet or capsule form. Alcohol and caffeine are ingested in beverage form; nicotine and cannabis are smoked or vaporized ; peyote and psilocybin mushrooms are ingested in botanical form or dried; and crystalline drugs such as cocaine and methamphetamine are usually inhaled or snorted. The theory of dosage, set, and setting

Source: SIPRI Defense economics is the financial and monetary efforts made to resource and sustain militaries, and to finance military operations , including war. The process of allocating resources
12900-421: The overarching goals of strategy . A common synonym is operational art. The operational level is at a scale bigger than one where line of sight and the time of day are important, and smaller than the strategic level, where production and politics are considerations. Formations are of the operational level if they are able to conduct operations on their own, and are of sufficient size to be directly handled or have
13029-417: The personnel, and maintenance for the equipment; the services to assist recovery of wounded personnel, and repair of damaged equipment; and finally, post-conflict demobilization , and disposal of war stocks surplus to peacetime requirements. Development of military doctrine is perhaps the most important of all capability development activities, because it determines how military forces are used in conflicts,
13158-476: The physicality of armed forces, their personnel , equipment , and the physical area which they occupy. As an adjective, military originally referred only to soldiers and soldiering, but it broadened to apply to land forces in general, and anything to do with their profession. The names of both the Royal Military Academy (1741) and United States Military Academy (1802) reflect this. However, at about
13287-408: The poison." Some compounds are beneficial or pleasurable when consumed in small amounts, but harmful, deadly, or evoke discomfort in higher doses. The set is the internal attitudes and constitution of the person, including their expectations, wishes, fears, and sensitivity to the drug.

Certain psychoactives, particularly hallucinogens, have been used for religious purposes since prehistoric times. Native Americans have used peyote cacti containing mescaline for religious ceremonies for as long as 5700 years. The muscimol -containing Amanita muscaria mushroom
13674-628: The problems and symptoms, but veterans years later often experienced those problems untreated and amplified. This is a large part of the reason why very few servicemen, compared to previous wars, required medical evacuation due to combat-stress breakdowns, but PTSD levels among veterans after the war are at unprecedented levels compared to previous wars. Nationals of other nations fought in the American-led anti-communist coalition, usually as armed forces of allied nations, such as Australia, New Zealand, Thailand , and South Korea , but sometimes as members of
13803-445: The rank hierarchy is common to all state armed forces worldwide. In addition to their rank, personnel occupy one of many trade roles, which are often grouped according to the nature of the role's military tasks on combat operations: combat roles (e.g. infantry ), combat support roles (e.g. combat engineers ), and combat service support roles (e.g. logistical support ). Personnel may be recruited or conscripted , depending on
13932-415: The recovery of defective and derelict vehicles and weapons, maintenance of weapons in the field, the repair and field modification of weapons and equipment; and in peacetime, the life-extension programmes undertaken to allow continued use of equipment. One of the most important role of logistics is the supply of munitions as a primary type of consumable, their storage, and disposal . The primary reason for
14061-599: The removal of unexploded mines and bombs, help people affected by Agent Orange , teach English to the Vietnamese and conduct Vietnam War battlefield tours for tourists. The Vietnam veteran has been depicted in fiction and film of variable quality. A major theme is the difficulties of soldiers readjusting from combat to civilian life. This theme had occasionally been explored in the context of World War Two in such films as The Best Years of Our Lives (1946) and The Men (1950). However, films featuring Vietnam veterans constitute
14190-432: The routine use of psychoactive drugs. He said that Jihan Wali , a captive kept in a nearby cell, was rendered catatonic through the use of these drugs. Alcohol has a long association of military use, and has been called " liquid courage " for its role in preparing troops for battle, anaesthetize injured soldiers, and celebrate military victories . It has also served as a coping mechanism for combat stress reactions and

"Drugs" can have a negative connotation, often associated with illegal substances like cocaine or heroin, despite the fact that the terms "drug" and "medicine" are sometimes used interchangeably. Novel psychoactive substances (NPS) , also known as " designer drugs " are
14835-684: The system chosen by the state. Most military personnel are males; the minority proportion of female personnel varies internationally (approximately 3% in India, 10% in the UK, 13% in Sweden, 16% in the US, and 27% in South Africa ). While two-thirds of states now recruit or conscript only adults, as of 2017 50 states still relied partly on children under the age of 18 (usually aged 16 or 17) to staff their armed forces. Whereas recruits who join as officers tend to be upwardly-mobile , most enlisted personnel have
14964-471: The terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police.

15351-554: The units deployed was to label them "military consultants." This deployment resulted in the development of the North Vietnamese air force, then it was formed against the United States' involvement in the war. From 1975 to 2002, forty-four Soviet servicemen were killed in Vietnam, mainly in aviation accidents. The military collaboration at Cam Ranh Base was continued by the later government of Russia until 2002. There are persistent stereotypes about Vietnam veterans as psychologically devastated, bitter, homeless, drug-addicted people, who had
15480-505: The war effort. Initially, New Zealand provided a 25-man team of RNZE engineers from 1964 to 1965.

Veterans, particularly in Southern California , were responsible for many of those early lobbying and subsequent Vet Center treatment programs. They founded one of
16383-718: Was one of a triumvirate of ' arts ' or 'sciences' that governed the conduct of warfare, the others being: military tactics , the execution of plans and manoeuvring of forces in battle , and maintenance of an army. The meaning of military tactics has changed over time; from the deployment and manoeuvring of entire land armies on the fields of ancient battles, and galley fleets; to modern use of small unit ambushes , encirclements , bombardment attacks, frontal assaults , air assaults , hit-and-run tactics used mainly by guerrilla forces, and, in some cases, suicide attacks on land and at sea. Evolution of aerial warfare introduced its own air combat tactics . Often, military deception , in
