The Kia Medium Tactical Vehicle is a South Korean tactical truck family covering 4x4 cargo, 6x6 cargo, and 6x6 bulletproof cargo branches.

Military Truck, Military logistics truck and tactical wheeled vehicle, Support EquipmentSupport EquipmentMilitary TruckMilitary logistics truck and tactical wheeled vehicleMilitary trucks are wheeled logistics and tactical support vehicles used for cargo movement, convoy sustainment, heavy-equipment transport, fuel and water distribution, and as chassis for road-mobile weapon systems. The class spans generic cargo trucks through tactical wheeled vehicle families such as FMTV, and conflict evidence on this page is limited to directly sourced Ukraine transfers and Afghanistan convoy operations.

Official Sisu material emphasizes off-road mobility, STANAG 4569-class protection options, a 16.5-tonne gross weight, and seating layouts from utility to 2+8 troop-transport configuration; Finnish and Swedish procurement has since expanded the family into TGB24 troop-transport, command, medical, CBRN, and air-defense roles, while 2026 defense reporting placed at least one GTP with Ukrainian Special Operations Forces without a public transfer route.
