Oshkosh Defense Medium Tactical Vehicle Replacement (MTVR)

Remotely Operated Ground Unit for Expeditionary Fires (ROGUE-Fires): Equipped with the Navy/Marine Expeditionary Ship Interdiction System (NMESIS), ROGUE-Fires delivers an expeditionary, land-based fires capability that enables sea denial and supports naval campaigns. Leveraging Oshkosh's mobility integration expertise, the system pairs advanced payloads and autonomy with the proven Oshkosh JLTV platform to perform in austere environments. It enables Marines to disperse, maneuver, and remain survivable while operating forward in contested maritime environments.

Medium Tactical Vehicle Replacement (MTVR): Also on display is the MTVR 4x4 equipped with exportable power and enhanced lighting. These enhancements strengthen the MTVR's core mission capabilities – logistical support, operational mobility, and transportability – while improving performance across current missions and expanding flexibility in distributed environments. The platform builds on proven mobility with targeted upgrades that extend service life and increase mission execution.

"Mobility enables how Marines fight and sustain combat power forward, and Oshkosh brings that capability to every platform we deliver," said Pat Williams, Chief Program Officer at Oshkosh Defense. "We develop robust, versatile platforms and provide the lifecycle support needed to keep them ready, relevant, and effective in contested environments. From autonomous fires to modernized mobility and integrated sustainment, our approach connects capability with long-term performance in the field."
