List of military strategies and concepts
Concepts: 

Economic concepts: Salaries – Always pay your troops on time.
Asymmetric costs – ensure the cost of enemy losses (or objectives) is at least an order of magnitude higher than the costs of attacking.
Budget like a business – Ensure there is sufficient funds and revenue streams to finish the war.

Strategic concepts: Center of gravity (military) – The hub of all power and movement on which everything depends, the point at which all energies should be directed
Culminating point – The point at which a military force is no longer able to perform its operations
Decisive point – A geographic place, specific key event, critical system, or function that allows commanders to gain a marked advantage over an enemy and greatly influence the outcome of an attack
DIME(FIL) – The elements of national power diplomacy, information, military, and economics, often included are financial, intelligence, and law enforcement see MIDLIFE
Expediency – War is a matter of expedients – von Moltke
Fog, friction, chance – War is characterized by fog, friction, and chance
Golden Bridge – To leave an opponent an opportunity to withdraw in order to not force them to act out of desperation – Sun Tzu
Iron Calculus of War – Resistance = Means x Will – Clausewitz
Moral ascendancy – Moral force is the trump card for any military event because as events change, the human elements of war remain unchanged – Du Piq
OODA loop – Decision-making occurs in a recurring cycle of observe-orient-decide-act. An entity (whether an individual or an organization) that can process this cycle quickly, observing and reacting to unfolding events more rapidly than an opponent, can thereby "get inside" the opponent's decision cycle and gain the advantage – Boyd
Paradoxical nature – The nature of strategy is a paradoxical and does not follow a linear pattern – Luttwak
Positive ends – The possibility of taking advantage of a new security environment to create conditions for long-term peace – Wass de Czege
Primary Trinity – (1) primordial violence, hatred, and enmity; (2) the play of chance and probability; and (3) war's element of subordination to rational policy – Clausewitz
Secondary Trinity – People, Army, and Government – Clausewitz
Principles of war:
Objective (Direct every military operation towards a clearly defined, decisive, and attainable objective)
Offensive (Seize, retain, and exploit the initiative)
Mass (Concentrate combat power at the decisive place and time)
Economy of Force (Allocate minimum essential combat power to secondary efforts)
Maneuver (place the enemy in a disadvantageous position through the flexible application of combat power)
Unity of Command (For every Objective, ensure Unity of effort under one responsible commander)
Security (Never permit the enemy to acquire an unexpected advantage)
Surprise (Strike the enemy at a time, at a place, or in a manner for which he is unprepared)
Simplicity (Prepare clear, uncomplicated plans and clear, concise orders to ensure thorough understanding) – US Army FM 3.0
Systems approach – Nation-states operate like biological organisms composed of discrete systems. These systems included: leadership, organic essentials, infrastructure, population, and the military – Warden
Tipping point – The point at which "the momentum for change becomes unstoppable." – Gladwell
VUCA – Volatility, uncertainty, complexity and ambiguity characterize the strategic environment – U.S. Army War College
Weinberger-Powell Doctrine – A list of questions have to be answered affirmatively before military action is taken by the United States:
Is a vital national security interest threatened?
Do we have a clear attainable objective?
Have the risks and costs been fully and frankly analyzed?
Have all other non-violent policy means been fully exhausted?
Is there a plausible exit strategy to avoid endless entanglement?
Have the consequences of our action been fully considered?
Is the action supported by the American people?
Do we have genuine broad international support?

Strategies: 

Defensive strategies: Boxing maneuver – A strategy used to "box in" and force an attack on all sides at once
Choke point – A use of strategic geography, usually in a narrow area, intended to concentrate the enemy into a confined area where the defender can maximize his forces
Defence in depth – A strategy to delay rather than prevent the advance of the attackers by buying time and causing additional casualties by yielding space so that the momentum of the attack is lost and the attacking force can be attacked on its flanks
Elastic Defense - A strategy to flexibly absorb then repel the advance of attackers through carefully planned integrated fighting positions.
Fortification – A semi-permanent or permanent defensive structure that gives physical protection to a military unit
Fabian strategy – Wearing down the enemy by using attrition warfare and indirection, while avoiding pitched battles or frontal assaults. Named after Quintus Fabius Maximus Verrucosus in his defense against Carthage. See Pyrrhic warfare
Military district – An area controlled by a military force, for administrative purposes rather than combat. Also known as Wehrkreis in German
Scorched earth – Destroying anything that might be of use to the enemy while retreating, or advancing
Turtling – Continuous reinforcement of the military front until it has reached its full strength, then an attack with the now-superior force
Withdrawal – A retreat of forces while maintaining contact with the enemy
High ground - An area of elevated terrain which can be useful in combat. Can provide structural advantages for positions of troops and weaponry which can be thrown or fired from above.

Offensive strategies: Air supremacy – A degree of air superiority where a side holds complete control of air power over opposing forces. Control of the air is the aerial equivalent of Command of the sea.
Attrition warfare – A strategy of wearing down the enemy to the point of collapse through continuous loss of personnel and material. Used to defeat enemies with low resources and high morale.
Bait and bleed – To induce rival states to engage in a protracted war of attrition against each other "so that they bleed each other white", similar to the concept of Divide and conquer
Battle of annihilation – The goal of destroying the enemy military in a single planned pivotal battle
Bellum se ipsum alet – A strategy of feeding and supporting an army with the potentials of occupied territories
Blitzkrieg – A method of warfare where an attacking force, spearheaded by a dense concentration of armoured and motorised or mechanised infantry formations with close air support, breaks through the opponent's line of defence by short, fast, powerful attacks and then dislocates the defenders, using speed and surprise to encircle them with the help of air superiority.
Blockade / Siege / Investment – An attempt to cut off food, supplies, war material or communications from a particular area by force, usually taking place by sea
Clear and hold – A counter-insurgency strategy in which military personnel clear an area of guerrillas or other insurgents, and then keep the area clear of insurgents while winning the support of the populace for the government and its policies.
Coercion – Compelling the enemy to involuntarily behave in a certain way by targeting the leadership, national communications, or political-economic centers
Command of the sea – A degree of naval superiority where a side holds complete control of naval power over opposing forces. Control of the sea is the naval equivalent of Air Supremacy
Counter-offensive – A strategic offensive taking place after the enemy's front line troops and reserves have been exhausted, and before the enemy has had the opportunity to assume new defensive positions. Tactic is usually implemented through surging at the enemy after their attack.
Counterforce – A strategy used in nuclear warfare of targeting military infrastructure (as opposed to civilian targets)
Countervalue – The opposite of counterforce; targeting of enemy cities and civilian populations. Used to distract the enemy.
Decapitation – Achieving strategic paralysis by targeting political leadership, command and control, strategic weapons, and critical economic nodes
Deception – A strategy that seeks to deceive, trick, or fool the enemy and create a false perception in a way that can be leveraged for a military advantage
Diversion - Any kind of attack used to divert the enemies' defenses away from where you intend to launch an incursion or strike.
Defeat in detail – Bringing a large portion of one's own force to bear on small enemy units in sequence, rather than engaging the bulk of the enemy force all at once. Similar to divide and conquer
Denial – A strategy that seeks to destroy the enemy's ability to wage war
Distraction – An attack by some of the force on one or two flanks, drawing up to a strong frontal attack by the rest of the force
Encirclement – Both a strategy and tactic designed to isolate and surround enemy forces
Ends, Ways, Means, Risk – Strategy is much like a three legged stool of ends, ways, means balanced on a plane of varying degree of risk
Enkulette – A strategy used often in the jungle that aims at attacking the enemy from behind.
Exhaustion – A strategy that seeks to erode the will or resources of a country
Feint –  A maneuver designed to distract or mislead, done by giving the impression that a certain maneuver will take place, while in fact another, or even none, will.
Flanking maneuver – Involves attacking the opponent from the side, or rear
Guerrilla tactics – Involves ambushes on enemy troops. Usually used by insurgency.
