What concept refers to the use of false information to mislead the enemy?

The concept that refers to the use of false information to mislead the enemy is deception. Deception is a fundamental aspect of military strategy that aims to create a false impression or understanding in the opponent’s mind. By manipulating perceptions and providing misleading information, a force can induce confusion, doubt, or miscalculation in the enemy, ultimately leading to tactical or strategic advantages in combat situations.

Deception can take many forms, including feints, misinformation, and strategic distractions, all designed to divert attention away from a force's true intentions or capabilities. For example, a military might simulate troop movements to suggest an attack where none is planned, or create the illusion of greater strength or resources than actually available.

In contrast, concealment refers to hiding true capabilities or positions without necessarily misleading the enemy with false information. Ambiguity involves creating uncertainty or vagueness, which does not inherently involve falsehoods. Obfuscation, while related, typically pertains to making information complex or confusing rather than outright false. These distinctions underscore why deception is the most appropriate choice for the definition provided in the question.
