// UNMANNED SYSTEMS AND NEXT-GEN WARFARE TERM
Stand-In Forces
Stand-In Forces are military units designed to operate deep within an adversary's weapon engagement zone, making them difficult to detect and target. They act as a persistent 'inside' presence to gather intelligence, disrupt enemy operations, and create opportunities for the larger joint force.
TECHNICAL DEFINITION
Stand-In Forces (SIF) are a core component of the U.S. Marine Corps' Force Design 2030 doctrine, representing small, low-signature, mobile units designed for persistent operations inside an adversary's Anti-Access/Area Denial (A2/AD) environment and weapons engagement zone (WEZ). These forces conduct reconnaissance, counter-reconnaissance, and precision strikes to disrupt enemy kill chains and enable joint force access and maneuver in contested littorals, particularly in the Indo-Pacific theater.
SYNONYMS & ALIASES
- SIF
- Inside Forces
- Contact Layer Forces
- EABO forces
- Forward-Positioned Forces
- Marine Littoral Regiment (MLR)
USAGE NOTE
The term is primarily associated with the U.S. Marine Corps' strategic shift to prepare for conflict with a peer adversary in a contested maritime environment.
DEVELOPERS
Organizations developing technology related to Stand-In Forces.
Develops AI-powered autonomous systems, including unmanned aerial systems (Altius), command and control software (Lattice), and sensor fusion technologies that directly enable the distributed sensing and strike capabilities required by Stand-In Forces.
A leading developer of small unmanned aircraft systems (UAS) and loitering missile systems, such as the Switchblade and Puma, which provide organic reconnaissance and precision strike capabilities to small, mobile units.
Co-developer of the Naval Strike Missile (NSM) and the prime integrator for the Navy/Marine Corps Expeditionary Ship Interdiction System (NMESIS), a key long-range, ground-based anti-ship capability designed to be operated by Stand-In Forces.
Specializes in artificial intelligence for aviation, developing an AI pilot called Hivemind that enables autonomous maneuvering and swarming for aircraft like its V-BAT UAS, suitable for expeditionary and low-footprint operations.
A major provider of resilient C4ISR technologies, including tactical radios, satellite communications, and electronic warfare systems, which are critical for connecting dispersed Stand-In Forces in contested communication environments.
Designs and manufactures wind and solar-powered unmanned surface vehicles (USVs) for long-duration maritime domain awareness. These platforms serve as persistent, low-signature sensors to detect and track targets for Stand-In Forces.
A Norwegian defense company that developed the Naval Strike Missile (NSM), the primary munition for the NMESIS system. The NSM provides stand-off, anti-ship capabilities essential for land-based forces to control sea lanes.
Develops data integration and analysis software platforms like Gotham, used to fuse sensor data from disparate sources into a common operating picture, enabling better and faster decision-making for dispersed command and control nodes.
