What tactical mission task physically renders an enemy force combat-ineffective?

The tactical mission task that physically renders an enemy force combat-ineffective is "Destroy." This term indicates a complete elimination of the enemy's capability to fight, ensuring that they can no longer conduct any military operations or pose a threat on the battlefield. In military terminology, destroying an enemy force may involve targeting and eliminating personnel, equipment, and infrastructure, leading to the total incapacitation of the target.

In contrast, "Defeat" typically refers to gaining the upper hand over an enemy, but does not imply total destruction; the enemy may be forced to withdraw or become ineffective without being completely annihilated. "Deceive" focuses on misdirection and misleading the enemy, which does not physically impair their capacity to fight. "Neutralize," while implying that an enemy force is rendered ineffective, often refers to making them less effective or temporarily incapacitating them rather than ensuring their complete destruction. Thus, "Destroy" is the clearest term for achieving total combat ineffectiveness.
