Raid, also known as depredation, is a military tactic or operational warfare mission which has a specific purpose and is not normally intended to capture and hold terrain, but instead finish with the raiding force quickly retreating to a previous defended position prior to the enemy forces being able to respond in a co-ordinated manner or formulate a counter-attack. Within the tactical mission, a raiding group may consist of personnel specially trained in this tactic (such as commandos or guerrilla fighters), regular soldiers, or any organized group of combatants.
