"In warfare, there are no constant conditions. He who can modify his tactics in relation to his opponent will succeed and win." (Sun Tzu, The Art of War, 5th century BC)
"All men can see these tactics whereby I conquer, but what none can see is the strategy out of which victory is evolved." (Sun Tzu, The Art of War, 5th century BC)
"When conventional tactics are altered unexpectedly according to the situation, they take on the element of surprise and increase in strategic value." (Sun Bin, Art of War, cca 4th century BC)
"The conduct of war, then, consists in the planning and conduct of fighting. If fighting consisted of a single act, no further subdivision would be needed. However, it consists of a greater or lesser number of single acts, each complete in itself, which [...] are called ‘engagements’ and which form new entities. This gives rise to the completely different activity of planning and executing these engagements themselves, and of coordinating each of them with the others in order to further the object of the war. One has been called tactics, and the other strategy." (Carl von Clausewitz, "On War", 1832)
"The distinction between tactics and strategy is now almost universal, and everyone knows fairly well where each particular factor belongs without clearly understanding why. Whenever such categories are blindly used, there must be a deep-seated reason for it. We have tried to discover the distinction, and have to say that it was just this common usage that led to it. We reject, on the other hand, the artificial definitions of certain writers, since they find no reflection in general usage." (Carl von Clausewitz, "On War", 1832)
"The theory of major operations (strategy, as it is called) presents extraordinary difficulties, and it is fair to say that very few people have clear ideas about its details - that is, ideas which logically derive from basic necessities." (Carl von Clausewitz, "On War", 1832)
"Thus, while a tactical reserve is a means not only of meeting any unforeseen manoeuvre by the enemy but also of reversing the unpredictable outcome of combat when this becomes necessary, strategy must renounce this means, at least so far as the overall decision is concerned. Setbacks in one area can, as a rule, be offset only by achieving gains elsewhere, and in a few cases by transferring troops from one area to another. Never must it occur to a strategist to deal with such a setback by holding forces in reserve." (Carl von Clausewitz, "On War", 1832)
"We have divided the conduct of war into the two fields of tactics and strategy. The theory of the latter, as we have already stated, will unquestionably encounter the greater problems since the former is virtually limited to material factors, whereas for strategic theory, dealing as it does with ends which bear directly on the restoration of peace, the range of possibilities is unlimited. As these ends will have to be considered primarily by the commander-in-chief, the problems mainly arise in those fields that lie within his competence. In the field of strategy, therefore, even more than in tactics, theory will be content with the simple consideration of material and psychological factors, especially where it embraces the highest of achievements." (Carl von Clausewitz, "On War", 1832)
"As regards tactics, the principal thing to be attended to is the choice of the most suitable order of battle for the object in view. When we come to consider the action of masses on the field, the means to be used may be an opportune charge of cavalry, a strong battery put in position and unmasked at the proper moment, a column of infantry making a headlong charge, or a deployed division coolly and steadily pouring upon the enemy a fire, or they may consist of tactical maneuvers intended to threaten the enemy’s flanks or rear, or any other maneuver calculated to diminish the confidence of the adversary. Each of these things may, in a particular case, be the cause of victory. To define the cases in which each should be preferred is simply impossible." (Antoine-Henri Jomini, "The Art of War", 1838)
"Every strategic line of defense should always possess a tactical point upon which to rally for defense should the enemy cross the strategic front. (Antoine-Henri Jomini, "The Art of War", 1838)
"Grand tactics is the art of making good combinations preliminary to battles, as well as during their progress. The guiding principle in tactical combinations, as in those of strategy, is to bring the mass of the force in hand against a part of the opposing army, and upon that point the possession of which promises the most important results. (Antoine-Henri Jomini, "The Art of War", 1838)
"Strategy, or the art of properly directing masses upon the theater of war, either for defense or for invasion. […] Strategy is the art of making war upon the map, and comprehends the whole theater of operations. Grand Tactics is the art of posting troops upon the battle-field according to the accidents of the ground, of bringing them into action, and the art of fighting upon the ground, in contradistinction to planning upon a map. Its operations may extend over a field of ten or twelve miles in extent. Logistics comprises the means and arrangements which work out the plans of strategy and tactics. Strategy decides where to act; logistics brings the troops to this point; grand tactics decides the manner of execution and the employment of the troops." (Antoine-Henri Jomini, "The Art of War", 1838)
"The tactical result of an engagement forms the base for new strategic decisions because victory or defeat in a battle changes the situation to such a degree that no human acumen is able to see beyond the first battle." (Helmuth von Moltke, "Über Strategie" ["On Strategy"], 1871)
"The world is a multiplicity, a harvest-field, a battle-ground; and thence arises through human contact ways of numbering, or mathematics, ways of tillage, or agriculture, ways of fighting, or military tactics and strategy, and these are incorporated in individuals as habits of life." (George Edward Woodberry, "The Torch, and Other Lectures and Addresses", 1920)
"Nine-tenths of tactics are certain, and taught in books: but the irrational tenth is like the kingfisher flashing across the pool, and that is the test of generals. It can only be ensured by instinct, sharpened by thought practicing the stroke so often that at the crisis it is as natural as a reflex." (Thomas E Lawrence, "The Evolution of A Revolt", 1920)
"In a physical contest on the field of battle it is allowable to use tactics and strategy, to retreat as well as advance, to have recourse to a ruse as well as open attack; but in matters of principle there can be no tactics, there is one straight forward course to follow and that course must be found and followed without swerving to the end." (Terence MacSwiney, "Principles of Freedom", 1921)
"The field of consciousness is tiny. It accepts only one problem at a time. Get into a fist fight, put your mind on the strategy of the fight, and you will not feel the other fellow's punches." (Antoine de Saint-Exupéry, "Flight to Arras", 1942)
"Keep the pressure on, with different tactics and actions, and utilize all events of the period for your purpose." (Saul Alinsky, "Thirteen Tactics for Realistic Radicals: from Rules for Radicals", 1971)
"One can become a master through experience and by practicing and learning tactics." (Kazumi Tabata, "Mind Power: Secret Strategies for the Martial Arts", 2010)
