Command hierarchy in the context of "1960 Turkish coup d'état"

Organizational theory refers to a series of interrelated concepts that involve the sociological study of the structures and operations of formal social organizations. Organizational theory also seeks to explain how interrelated units of organization either connect or do not connect with each other. Organizational theory also concerns understanding how groups of individuals behave, which may differ from the behavior of an individual. The behavior organizational theory often focuses on is goal-directed. Organizational theory covers both intra-organizational and inter-organizational fields of study.

In the early 20th century, theories of organizations initially took a rational perspective but have since become more diverse. In a rational organization system, there are two significant parts: Specificity of Goals and Formalization. The division of labor is the specialization of individual labor roles, associated with increasing output and trade. Modernization theorist Frank Dobbin wrote that "modern institutions are transparently purposive and that we are in the midst of an extraordinary progression towards more efficiency." Max Weber's conception of bureaucracy is characterized by the presence of impersonal positions that are earned and not inherited, rule-governed decision-making, professionalism, chain of command, defined responsibility, and bounded authority. Contingency theory holds that an organization must try to maximize performance by minimizing the effects of various environmental and internal constraints, and that the ability to navigate this requisite variety may depend upon the development of a range of response mechanisms.

The Oberkommando der Wehrmacht (German: [ˈoːbɐkɔˌmando deːɐ̯ ˈveːɐ̯ˌmaxt] ; abbreviated OKW [oː kaːˈve] Armed Forces High Command) was the supreme military command and control staff of Nazi Germany during World War II, that was directly subordinated to Adolf Hitler. Created in 1938, the OKW replaced the Reich Ministry of War and had nominal oversight over the individual high commands of the country's armed forces: the army (Heer), navy (Kriegsmarine) and air force (Luftwaffe). With the start of World War II, tactical control of the Waffen-SS was also exercised by it. There was no direct chain of command between the OKW and the other High Commands.

Rivalry with the different services' commands, mainly with the Army High Command (OKH), prevented the OKW from becoming a unified German General Staff in an effective chain of command, though it did help coordinate operations among the three services. During the war, the OKW acquired more and more operational powers. By 1942, the OKW had responsibility for all theatres except for the Eastern Front. However, Hitler manipulated the system in order to prevent any one command from taking a dominant role in decision making. This "divide and conquer" method helped put most military decisions in Hitler's own hands, which at times included even those affecting engagements at the battalion level, a practice which, due to bureaucratic delays and Hitler's worsening indecision as the war progressed, would eventually contribute to Germany's defeat.

Military ranks are a system of hierarchical relationships within armed forces, police, intelligence agencies and other institutions organized along military lines. Responsibility for personnel, equipment and missions grows with each advancement. The military rank system defines dominance, authority and responsibility within a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command is an important component for organized collective action.

Uniforms denote the bearer's rank by particular insignia affixed to the uniforms of a number of countries. Ranking systems have been known for most of military history to be advantageous for military operations, in particular with regards to logistics, command, and coordination. As time went on and military operations became larger and more complex, more ranks were created and the systems of ranking became more complex.

The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, which advises the president of the United States, the secretary of defense, the Homeland Security Council and the National Security Council on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of a chairman, a vice chairman, the chiefs of the Army, Marine Corps, Navy, Air Force, and Space Force, and the chief of the National Guard Bureau. Each of the individual service chiefs, outside their Joint Chiefs obligations, works directly under the secretaries of their respective military departments, e.g. the secretary of the Army, the secretary of the Navy, and the secretary of the Air Force.

Following the Goldwater–Nichols Act in 1986, the Joint Chiefs of Staff do not have operational command authority, either individually or collectively, as the chain of command goes from the president to the secretary of defense, and from the secretary to the regional combatant commanders. Goldwater–Nichols also created the office of vice chairman, and the chairman is now designated as the principal military adviser to the secretary of defense, the Homeland Security Council, the National Security Council and the president.

Ranks and insignia were used by the National Socialist German Workers' Party (NSDAP) as paramilitary titles between approximately 1928 and the fall of Nazi Germany in 1945. Such ranks were held within the political leadership corps of the Nazi Party, charged with the overseeing of the regular Nazi Party members.

The first purpose of the Nazi Party's political ranks was to provide election district leadership positions during the years where the Nazis were attempting to come to power in Germany. After 1933, when the Third Reich had been established, Nazi Party ranks played a much more important role existing as a political chain of command operating side by side with the German government.
