THeMIS
Estonian multi-mission UGV for military support and combat.
The THeMIS (Tracked Hybrid Modular Infantry System) is an unmanned ground vehicle (UGV) built by Estonia’s Milrem Robotics for military use. This ground-based armed drone supports dismounted troops by acting as a transport platform, remote weapon station, and IED detection and disposal unit. Its open architecture allows for multiple mission roles.
The Transport variant focuses on base logistics and last-mile resupply for frontline units, reducing soldiers’ physical and cognitive load while improving standoff distance, force protection, and survivability. Combat UGVs serve as force multipliers by providing direct fire support for maneuvering forces. These vehicles feature a self-stabilizing remote-controlled weapon system for high-precision engagement day or night, increasing standoff and protection. They can be fitted with light or heavy machine guns, 40 mm grenade launchers, 30 mm autocannons, and anti-tank missile systems.
ISR variants carry advanced multi-sensor intelligence-gathering equipment to boost situational awareness, surveillance, reconnaissance, and battle damage assessment over wide areas. They help infantry, border guards, and law enforcement collect and process raw information, cutting commander reaction times. THeMIS can fire conventional machine gun ammunition or missile rounds.
In September 2020, Estonia and the Netherlands jointly acquired seven THeMIS UGVs after extensive testing by both armies. In September 2022, Milrem delivered THeMIS units for casualty evacuation and supply transport to Ukraine. That November, Germany’s defense ministry, through Krauss-Maffei Wegmann, contracted for 14 more THeMIS vehicles for Ukraine. The system has been exported to NATO members and allies including Australia, France, Germany, the Netherlands, Norway, the United Kingdom, Ukraine, and the United States.
Operators include the Danish Defence, Estonian Defence Forces, Indian Armed Forces, Royal Netherlands Army, Spanish Armed Forces (first unit received August 2022), Swedish Armed Forces, Royal Thai Army, and Armed Forces of Ukraine.

Lore & Background
The THeMIS was developed by Milrem Robotics in Estonia as a tracked, hybrid modular infantry system. Its open architecture allows it to be configured for multiple missions, including transport, combat, and intelligence gathering. The THeMIS Transport variant is designed to support onbase logistics and provide last mile resupply for frontline units, reducing the physical and cognitive load on infantry while increasing standoff distance, force protection, and survivability. The Combat UGV provides direct fire support for manoeuvre forces, acting as a force multiplier with an integrated self-stabilizing remote-controlled weapon system that offers high precision over wide areas day and night. It can be equipped with light or heavy machine guns, 40 mm grenade launchers, 30 mm autocannons, and Anti-Tank Missile Systems. The ISR variant features advanced multi-sensor intelligence gathering capabilities to increase situational awareness and provide improved intelligence, surveillance, and reconnaissance over wide areas, as well as battle damage assessment. It can fire conventional machine gun ammunition or missile rounds.
Reader's Guide
The THeMIS has been exported to several NATO members and allies, including Australia, France, Germany, the Netherlands, Norway, the United Kingdom, Ukraine, and the United States. In September 2020, Estonia and the Netherlands jointly acquired 7 THeMIS UGVs after extensive testing by both nations' armies. In September 2022, Milrem Robotics delivered THeMIS UGVs suited for casualty evacuation and transportation of supplies to Ukraine. In November 2022, the German Ministry of Defense, through Krauss-Maffei Wegmann (KMW), signed a contract to deliver another 14 THeMIS UGVs to Ukraine. The system's significance lies in its modular design, which allows it to adapt to various battlefield roles—from logistics and resupply to direct fire support and reconnaissance—thereby enhancing the effectiveness of dismounted infantry, border guards, and law enforcement agencies. Its ability to collect and process raw information and decrease reaction time for commanders, combined with its force protection and survivability features, has made it a notable asset in modern military operations.
