Which source of supply manages and purchases common consumable items used by all military services and some civilian agencies?

The Defense Logistics Agency (DLA) is responsible for managing and purchasing common consumable items that are utilized by all branches of the military, as well as various civilian agencies. This includes a wide range of supplies and logistics support, ensuring that essential items are readily available to meet operational needs. DLA's broad scope makes it a central authority for coordinating supply needs across different military branches, streamlining the procurement processes, and enhancing overall logistics efficiency.

Other agencies like the Air Force Supply Command, Army Logistics Command, and Navy Supply Systems Command focus more on supply requirements specific to their respective service branches. While they may manage logistics and supply chains for their forces, they do not have the same overarching responsibility to procure and manage common consumable items across all services and civilian agencies as DLA does. This makes DLA unique in its capability and responsibility within the logistics framework of the military.
