Modification Kits

The LI 4620 - Items under $5 million (Comm & Elec) program is a Marine Corps procurement line item within the Department of the Navy's FY 2026 budget, supporting a diverse set of communications and electronics equipment acquisitions. Its primary objective is to provide the Marine Corps with modern, deployable, and sustainable hardware and software solutions under $5 million per unit, enhancing operational readiness and supporting command and control functions. The program covers a wide range of equipment, including cameras, laptops, software, satellite dishes, and upgrades, all tailored to meet evolving mission requirements and maintain technological relevance.

Digital Media Systems (DMS) is a key component, with FY 2026 funding allocated for Internet Protocol Transmission Systems and a refresh of video cameras for the Visual Information Acquisition System. DMS enables Marine Corps Communication Strategy (COMMSTRAT) professionals to acquire, produce, and disseminate visual information and reprographic products, supporting operational requirements and communication objectives globally. The systems are designed to ensure 24/7 access to high-quality information products, which are critical for planning, battlespace awareness, and decision-making. DMS also supports the Marine Corps' reputational narrative and force resiliency by enabling engagement with key domestic and foreign publics.

Combat Optics is the largest funded subprogram in FY 2026, supporting the procurement of advanced optical systems. This includes Squad Binocular Night Vision Goggles, Binocular Night Vision Devices, Squad Common Optics, Squad Aiming Lasers, Long Range Thermal imagers, and Long Range Sniper Rifle Night Sights. These systems provide Marines with enhanced capabilities for target detection, recognition, and engagement in daylight and low-light conditions, improving lethality and mission success. The procurement schedule reflects the completion of some optics programs and the initiation or expansion of others, such as increased fielding of night vision devices and aiming lasers to support close combat and support units.

Test, Evaluation, & Engineering Environment (TEEE) receives funding to maintain and recapitalize the Marine Corps Tactical Systems Support Activity's (MCTSSA) infrastructure. As a designated Science & Technology Reinvention Lab, MCTSSA provides a controlled environment for enterprise-level testing, engineering, and analysis of C5I (Command, Control, Computers, Communications, Cyber, and Intelligence) systems. The funding ensures that over forty Marine Corps C5I programs can be evaluated and supported throughout their acquisition lifecycle, reducing program risk and identifying deficiencies prior to fielding.

Military Information Support Operations (MISO) and the Marine Corps Information Operations Program (MCIOP) are funded to enhance the Marine Air-Ground Task Force (MAGTF) Commander's ability to shape the information environment. MISO funding supports the Fly Away Broadcast System (FABS) Marine Corps Variant, providing portable broadcast capabilities to influence foreign groups and counter adversarial narratives. MCIOP funding supports equipment for remote Information Warfighter Exercise training sites, which are essential for delivering full-spectrum Operations in the Information Environment and integrating psychological operations across joint and coalition settings.

Signature Management (SIGMAN) continues the procurement and fielding of YETI systems and other electromagnetic signature management tools. SIGMAN enables commanders to visualize and minimize their forces' electromagnetic signatures, reducing detection and targeting risk while supporting distributed operations. Details on YETI are classified, but the program supports Force Design goals and provides tools for both signature visualization and disruption of adversary units.

Additional objectives within LI 4620 include funding for MAGTF Logistics Support Systems, which ensures hardware refreshes for handheld terminals and portable deployment kits, maintaining in-transit visibility of Marine Corps assets. The Item Unique Identification program is funded for technology refreshes of Integrated Marking Carts, supporting compliance with DoD mandates for asset accountability and auditability. These investments ensure the Marine Corps maintains a technologically advanced, resilient, and responsive communications and electronics capability across its operational spectrum.
