Sisu GTP is a Finnish 4x4 protected mobility vehicle built by Sisu Auto around a modular crew cab and interchangeable mission bodies. 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.
MILMAG and Defence Blog reported in April 2026 that at least one Finnish-made Sisu GTP 4x4 had appeared with Ukrainian Special Operations Forces; MILMAG, citing Andrii Kharuk, linked one vehicle to the 8th Separate Special Purpose Regiment, while both sources noted that no Finnish or Swedish public donation announcement confirmed the transfer route.
Role detailsSisu's public product data presents the GTP as a modular protected vehicle rather than a single fixed troop-carrier layout. The same 4x4 baseline supports crew-cab, squad, reconnaissance, and utility seating options, with protection and equipment kits selected for the mission.
Length 6,000 mm, width 2,500 mm, height 2,559 mm, 16,500 kg gross weight, and up to 5,000 kg payload.

Independent suspension, lockable differentials on each axle, optional central tire inflation, more than 100 km/h maximum road speed, over 600 km range, and 1,200 mm fording depth.

Swedish FMV reporting adds a clearer view of how the modular GTP/TGB24 chassis is being used beyond protected troop transport. Sweden's KRR short-range radar package mounts Saab's Giraffe 1X radar, command system, and deployable mast on the Sisu GTP/TGB24, while Saab's Gute demonstration used Sisu GTP vehicles with Giraffe 1X and Trackfire ARES in a mobile counter-UAS kill chain.
Ten Swedish short-range radar systems were ordered from Saab, with Giraffe 1X equipment mounted on Sisu GTP/TGB24 vehicles.
