What is the Sustainment warfighting function?

• A. Planning and executing provisioning, maintenance, supply, and services to sustain operations
• B. Managing information for decision-making
• C. Delivering fires to defeat or influence enemy
• D. Providing security and counter-threat actions

Answer: (A)

Sustainment focuses on providing the resources and services that keep a force in the fight. It involves planning and executing provisioning, maintenance, supply, and services so units can operate continuously. By ensuring the right materials reach the right units at the right time, keeping equipment in working order, and delivering essential support services (transport, medical care, upkeep, quality of life, and other logistics activities), sustainment enables operations to continue and supports every other warfighting function. The other options describe different warfighting functions: managing information for decision-making relates to command and control, delivering fires aligns with Fires, and providing security and counter-threat actions aligns with Protection.
