____ is the primary source of resupply in theater.

• A. TLAMM
• B. LOGPAC
• C. Supply Convoy
• D. Airlift

Answer: (A)

The main idea here is that sustainment in theater hinges on a single, centralized logistics system that coordinates demand, prioritizes needs, and routes supplies across the theater. TLAMM serves as that hub, handling requests from units, validating priorities, and allocating materiel so it can be delivered where and when it’s needed. It provides the visibility and control that tell the rest of the system what to move, from which depots, and along which delivery channels.

The other options are execution methods: a LOGPAC is a packaged shipment sent to a unit; a supply convoy is a ground transport method; airlift is delivery by air. These are how supplies move, but they rely on the TLAMM plan and prioritization to determine what and when to send. That central coordination makes TLAMM the primary source of resupply in theater.
