Which sustainment-mitigation measure is used for long-duration campaigns?

• A. Diversified Sourcing
• B. Centralized Sourcing on a Single Supplier
• C. Eliminate Maintenance Cycles
• D. In-Theater Production Only

Answer: (A)

Diversified sourcing is the best fit for long-duration campaigns because it builds redundancy and resilience in the supply chain. By pulling from multiple suppliers, regions, and logistics routes, you create options to reroute orders or substitute sources if one link in the chain is disrupted by a strike, port closure, quality issue, or geopolitical event. This keeps materials, parts, and support flowing over extended periods and helps stabilize availability and costs through market competition.

Relying on a single supplier creates a critical vulnerability: any disruption to that supplier can halt sustainment for the entire campaign. Eliminating maintenance cycles would undermine readiness and safety rather than preserve it, addressing a different objective and potentially causing more failures in the field. In-theater production only sounds self-sufficient but often cannot meet all needs for a long campaign due to capacity limits, resource constraints, and the risk of bottlenecks; diversification offers greater adaptability and continuity across a longer timeline.
