Define "combat service support."

Combat service support refers to the essential services required to sustain and maintain military operations in the field. This includes logistics, transportation, medical support, supply chain management, maintenance, and other critical services that ensure combat forces can operate effectively and efficiently over time. Without adequate combat service support, even the most capable combat units would struggle to function, as their operations rely heavily on timely resupply and support to maintain equipment, provide medical care, and facilitate movement.

The focus of combat service support is on enabling the overall mission by ensuring that troops have the necessary resources and infrastructure. This distinguishes it from other options, which are more narrowly focused on specific aspects of military operations, such as individual training, intelligence, or strategizing, rather than the comprehensive support network essential for sustained operations in combat scenarios.
