Episode notes
SIF Is A Service-Agnostic Concept
- The stand-in force (SIF) is a descriptive, service-agnostic concept for small, lethal, mobile forces operating in contested areas.
- SIF includes any formation matching that definition, not just Marine units.
MLR Purpose And Structure
- The Marine Littoral Regiment (MLR) is a reconfigured infantry regiment with three battalions for littoral missions.
- It provides maritime domain awareness, long-range fires, and contributes to sea denial and distributed joint operations.
MLR Mission Tied To SIF Role
- The MLR's mission statement explicitly ties it to the stand-in force role in contested littorals.
- It focuses on reconnaissance, counter-reconnaissance, and sea denial to support maritime campaigns.
