The future of Marine Corps reconnaissance vehicles hit the water in January and February 2026, as the Advanced Reconnaissance Vehicle (ARV) prototypes successfully completed their first full swim tests. The milestone event, conducted by the Textron Systems, General Dynamics Land Systems (GDLS), and Program Manager Light Armored Vehicles (PM LAV), marks a critical step forward in a rapid-prototyping effort to deliver a next-generation capability to the Fleet Marine Force.

In a direct response to evolving battlefield threats and critical personnel and infrastructures, the U.S. Marine Corps has conducted an expedited fielding and training approach for its Organic-Counter Small Unmanned Aircraft Systems (O-CsUAS) dismounted equipment across the Fleet Marine Force. This initiative represents a significant step in rapid technology adoption, moving a critical defense capability from the development pipeline directly into the hands of the warfighter.
In September, the Marine Corps unveiled the first full-rate production version of the Marine Air Defense Integrated System (MADIS), marking a major milestone in expeditionary air defense and rapid capability delivery. Following weeks of intensive New Equipment Training (NET) and a live-fire exercise at the Marine Corps Air Ground Combat Center, Marines are now equipped with a significantly upgraded system designed to counter the evolving threat of Unmanned Aerial Systems (UAS) and low-altitude air attacks.
This summer, Program Executive Office Land Systems hosted two interns for eight weeks through the Defense Civilian Training Corp’s (DCTC) program. David Appelt, a rising senior at Virginia Tech, majoring in cybersecurity management analytics, and Rithwick Erabelly, a rising senior at Purdue University, majoring in aerospace engineering, made their mark at PEO LS by developing a digital wargame to help Marine Corps small unit leaders strategically deploy counter-unmanned aircraft systems (C-UAS) capabilities – an increasingly significant part of modern-day warfare.
