Instrumented Tactical Engagement System (I-TESS). I-TESS will be used to support direct force-on-force tactical engagement training. This system will consist of the following type components: Small Arms Transmitter (SAT), Man-worn Detection System (MDS), Command and Control (C2 - mobile & portable versions), and Military Operations in Urban Terrain (MOUT) Building Instrumentation, and Simulated Battlefield Weapons. The SAT will be used on the M4 and M16 type rifles and the M249 Squad Automatic Weapon. The MDS and range equipment will be used to instrument the individual Marine for direct force-on-force engagement adjudication and to include the ability to support instrumentation functions such as PLI reporting. The I-TESS is used in MOUT Facilities and Non-Live Fire Maneuver Ranges located at various Marine Corp bases and installations.

Combat Vehicle-Tactical Engagement System (CV-TESS). CV-TESS is mounted on combat vehicles to simulate realistic force-on-force training. This system will use laser, detectors, video and audio on M1A1 tanks, Light Armored Vehicles (LAV) and Amphibious Assault Vehicles (AAV) to simulate battlefield engagements with the vehicle’s primary and secondary weapons as well as provide After Action Review (AAR) to enhance gunnery proficiency without expending live ammunition. CV-TESS will provide combat vehicle crews the ability to communicate, maneuver and engage against a real thinking adversary. Upon completion of the developmental efforts, CV-TESS will be fully integrated with the vehicle fire control system and require crew members to perform all duties exactly as they would in combat as well as providing the capability of mechanized units to train in real time combat simulations.

Mobile Fire Support Trainer (MFST). MFST is a planned future acquisition project to enhance Force-on-Force (FOF) training of call-for-fire and close-air support. It is an augmented reality training system that integrates with the USMC’s ground combat team training instrumentation system, the I-TESS II, to display virtual indirect fire effects onto actual terrain.

Operational Impact

The Marine Corps requires training systems that provide real-time situation awareness, exercise control capabilities, and adjudicate indirect fire engagements so as to help facilitate the training exercise objectives. There is a need to collect the training actions/interactions of the Marines during the training exercise with the ability to provide immediate access of collected data for After Action Review purposes.

Program Status

The Marine Corps is in the process of developing the documentation to compete the three efforts mentioned above in FY-19.

Three squads were tasked with the mission to capture and occupy Combat Town while a fourth squad acted as an opposing force. Gadaire, a Helena, Mont., native, is a combat engineer with Combat Logistics Battalion 4, Combat Logistics Regiment 3, 3rd Marine Logistics Group, III Marine Expeditionary Force.
