What is the duration of sustainment for a Marine Expeditionary Force?

The duration of sustainment for a Marine Expeditionary Force (MEF) is typically established at 60 days. This timeframe is based on operational planning and logistics, which ensures that a MEF can effectively conduct sustained operations without immediate resupply. The 60-day sustainment period allows for essential supplies, including food, ammunition, maintenance parts, and other logistical needs, to be stockpiled and managed, ensuring that Marines remain combat-effective throughout their mission. Understanding this sustainment timeframe is critical for planning and executing maritime operations, as it provides a benchmark for deployments and operational readiness in various scenarios.
