Army Field Manual (two volumes) – provides practices
Land component handbooks and special to arm publications – provide procedures
The Army Field Manual comprises Volumes 1 (Combined Arms Operations) in 12 parts led by "Formation Tactics" and "Battlegroup Tactics", and Volume 2 (Operations in Specific Environments) in 6 parts (desert, urban, etc.).
BDD is divided into two parts: "Defence Context" and "Military Doctrine". Defence Context deals with two matters. First, the relationship between Defence policy and military strategy, and—while highlighting the utility of force – emphasizes the importance of addressing security issues through a comprehensive, rather than an exclusively military, approach. Second it expounds the Nature of and the Principles of War, the three Levels of Warfare (Strategic, Operational and Tactical) and its evolving character. The ten Principles of War are a refined and extended version of those that appeared in FSR between the two world wars and based on the work of JFC Fuller.
The Military Doctrine states that it comprises national Joint Doctrine, Higher Level Environmental Doctrine, Tactical Doctrine, Allied Doctrine and doctrine adopted or adapted from ad hoc coalition partners. The part deals with three matters. First it describes the likely employment of the British Armed Forces in pursuit of Defence policy aims and objectives. Next it explains the three components of fighting power (conceptual, physical and moral components) and the criticality of the operating context to its effective application. Finally it describes the British approach to the conduct of military operations—"the British way of war". This includes mission command, the manoeuvrist approach and a warfighting ethos that requires accepting risks.
The BDD is linked to a variety of unclassified policy documents such as Defence White Papers and Strategic Defence Reviews, as well as classified Strategic Planning Guidance. The current, 2011, edition of BDD is underpinned by recent developmental and conceptual publications such as The DCDC Global Strategic Trends Programme 2007–2036 and The High Level Operational Conceptual Framework, which comprises specific army, navy and air force publications.

United States: 

Sources: The United States Constitution invests Congress with the powers to provide for the common defense and general welfare of the United States and to raise and support armies. Title 10 of the United States Code states what Congress expects the Army, in conjunction with the other Services, to accomplish. This includes: Preserve the peace and security and provide for the defense of the United States, its territories and possessions, and any areas it occupies; Support national policies; Implement national objectives; Overcome any nations responsible for aggressive acts that imperil the peace and security of the United States.

Key concepts: Most modern US doctrine is based around the concept of power projection and full spectrum operations, which combine offensive, defensive, and stability or civil support operations simultaneously as part of an interdependent joint or combined force to seize, retain, and exploit the initiative. They employ synchronized action—lethal and nonlethal—proportional to the mission and informed by a thorough understanding of all dimensions of the operational environment.
Offensive operations defeat and destroy enemy forces, and seize terrain, resources, and population centers. They impose the commander's will on the enemy. Defensive operations defeat an enemy attack, gain time, economize forces, and develop conditions favorable for offensive or stability operations.
Stability operations encompass various military missions, tasks, and activities conducted abroad to maintain or reestablish a safe and secure environment, provide essential governmental services, emergency infrastructure reconstruction, and humanitarian relief. Civil support operations are support tasks and missions to homeland civil authorities for domestic emergencies, and for designated law enforcement and other activities. This includes operations dealing with the consequences of natural or manmade disasters, accidents, and incidents within the homeland.
Under President Lyndon Johnson it was stated that the US armed forces should be able to fight two—at one point, two-and-a-half—wars at the same time. This was defined to mean a war in Europe against the Soviet Union, a war in Asia against China or North Korea, and a "half-war" as well—in other words, a "small" war in the Third World. When Richard Nixon took office in 1969, he altered the formula to state that the United States should be able to fight one-and-a-half wars simultaneously.
This doctrine remained in place until 1989–90, when President George H. W. Bush ordered the "Base Force" study which forecast a substantial cut in the military budget, an end to the Soviet Union's global threat, and the possible beginning of new regional threats. In 1993, President Bill Clinton ordered a "Bottom-Up Review", based on which a strategy called "win-hold-win" was declared—enough forces to win one war while holding off the enemy in another conflict, then moving on to win it after the first war is over. The final draft was changed to read that the United States must be able to win two "major regional conflicts" simultaneously.
The current strategic doctrine, which Defense Secretary Donald Rumsfeld issued in his Quadrennial Defense Review of early 2001 (before the 9/11 attacks), is a package of U.S. military requirements known as 1-4-2-1. The first 1 refers to defending the US homeland. The 4 refers to deterring hostilities in four key regions of the world. The 2 means the US armed forces must have the strength to win swiftly in two near-simultaneous conflicts in those regions. The final 1 means that the US forces must win one of those conflicts "decisively".
The general policy objectives are to (1) assure allies and friends; (2) dissuade future military competition, (3) deter threats and coercion against U.S. interests, and (4) if deterrence fails, decisively defeat any adversary.

United States Department of Defense: The Department of Defense publishes Joint Publications which state all-services doctrine. The current basic doctrinal publication is Joint Publication 3-0, "Doctrine for Joint Operations".

United States Air Force: Headquarters, United States Air Force, publishes current USAF doctrine. The lead agency for developing Air Force doctrine is the LeMay Center for Doctrine Development and Education; the Air Staff International Standardization Office works on multinational standardization, such as NATO Standardization Agreements (STANAGs), and agreements between the American, British, Canadian, and Australian Armies and Navies (ABCA) that affect the Air Force. Currently the basic Air Force doctrinal documents are the 10-series of Air Force publications.

United States Army: The United States Army Training and Doctrine Command (TRADOC) is responsible for developing Army doctrine. TRADOC was developed early in the 1970s as a response to the American Army's difficulties in the Vietnam War, and is one of the reforms that improved Army professionalism. Currently the capstone Army doctrinal document is Army Doctrine Publication 3-0, Unified Land Operations (published October 2011).

United States Navy: The Naval Warfare Development Command (NWDC) Doctrine Department coordinates development, publication, and maintenance of United States Navy doctrine. Currently the basic unclassified naval doctrinal documents are Naval Doctrine Publications 1, 2, 4, 5, and 6. NWDC is also the United States Navy lead for NATO and multinational maritime doctrine and operational standardization.

United States Marine Corps: The Marine Corps Combat Development Command (MCCDC) has responsibility for United States Marine Corps doctrine. The capstone doctrinal document is Warfighting (MCDP1), along with MCDP's 1-1, 1–2, and 1–3 (Strategy, Campaigning, and Tactics, respectively). MCDP 1-0 (Marine Corps Operations) translates the philosophical-based capstone/keystone publications into operational doctrine.

United States Coast Guard: Headquarters, United States Coast Guard, published Coast Guard Publication 1, U.S. Coast Guard: America's Maritime Guardian, which is the source of USCG doctrine.

SFR Yugoslavia: With the passing of the National Defense Law of 1969, Yugoslavia adopted a total war military doctrine named Total National Defense or Total People's Defense[b]. It was inspired by the Yugoslav People's Liberation War against the fascist occupiers and their collaborators in the Second World War, and was designed to allow Yugoslavia to maintain or eventually reestablish its independent and non-aligned status should an invasion occur. According to it, any citizen who resists an aggressor is a member of the armed forces, thus the whole population could be turned into a monolithic resistance army.
Starting from the elementary school education, over high schools, universities, organizations and companies, the authorities prepared the entire population to contest an eventual occupation of the country and finally to liberate it. For this purpose, the Territorial Defense Forces (TO) would be formed to mobilize the population in case of an aggression. The combat readiness of the TO meant that the steps of organization and training could be bypassed after the start of hostilities. The TO would supplement the regular Yugoslav People's Army, giving it greater defensive depth and an armed local population ready to support combat actions. Large numbers of armed civilians would increase the cost of an invasion to a potential aggressor.
The most likely scenario in the doctrine being used was a general war between the NATO and the Warsaw Pact.
