It is often advantageous to place the queen behind one or both rooks as it is a more valuable piece. This is known as Alekhine's gun (diagram at right) and can be extremely dangerous. Other batteries can be formed by rook-queen or bishop-queen.Ī triple battery can be constructed with the queen and both rooks. The most common kind of battery is the doubling of rooks on a file. Tactics are usually used to spoil the running context.Batteries are formed when two or more pieces work together. Tactics cut across a strategic field, exploiting gaps in it to generate novel and inventive outcomes. Tactics, then, are isolated actions or events that take advantage of opportunities offered by the gaps within a given strategic system, although the tactician never holds onto these advantages. A tactic is deployed “on and with a terrain imposed on it and organized by the law of a foreign power.” One who deploys a tactic “must vigilantly make use of the cracks that particular conjunctions open in the surveillance of the proprietary powers. … The space of a tactic is the space of the other” (ibid., 36-37). “A tactic is a calculated action determined by the absence of a proper locus. However, unlike strategy, which inherently creates its own autonomous space: Referring to non-military uses of the term, in his work The Practice of Everyday Life, French scholar Michel de Certeau suggests strategy and tactics are alike in that they both operate in space and time. The tactics involved might describe specific actions taken in specific locations, like surprise attacks on military facilities, missile attacks on offensive weapon stockpiles, and the specific techniques involved in accomplishing such objectives. If, for example, the overall goal is to win a war against another country, one strategy might be to undermine the other nation's ability to wage war by preemptively annihilating their military forces. Activities at this level focus on the ordered arrangement and maneuver of combat elements in relation to each other and to the enemy to achieve combat objectives. The level of war at which battles and engagements are planned and executed to accomplish military objectives assigned to tactical units or task forces. The United States Department of Defense Dictionary of Military Terms defines the tactical level as The terms tactic and strategy are often confused: tactics are the actual means used to gain an objective, while strategy is the overall campaign plan, which may involve complex operational patterns, activity, and decision-making that lead to tactical execution. In military usage, a military tactic is used by a military unit of no larger than a division to implement a specific mission and achieve a specific objective, or to advance toward a specific target.
