A strategic approach that seeks to win by wearing down the enemy through continuous losses in personnel and materiel, relying on superior resources or willpower to outlast the opponent.

Maneuver Warfare

A military approach that emphasizes speed, surprise, and the disruption of the enemy's decision-making and cohesion rather than the direct destruction of forces, seeking to collapse the opponent's ability to fight.

Clausewitzian Trinity

Combined Arms

The integration of different combat arms—infantry, armor, artillery, aviation, and engineers—so that each arm's strengths compensate for the others' weaknesses, creating a force more effective than the sum of its parts.

Logistics
