The SISU GTP is a 4x4 armored vehicle designed and manufactured by the Finnish company Oy Sisu Auto Ab. The first version was produced in 2019. In June 2020 the Finnish Defense Forces ordered 6 vehicles for testing.

The Sisu GTP is designed using a highly modular structure, which enables numerous variants for different operational uses, all using the same backbone structure. For example, the General Purpose body for 2+2 or 2+3 crew, and the APC (Armored Personnel Carrier) body for 2+8 crew are interchangeable quickly even in field conditions.

The Sisu GTP is based on a 4x4 wheeled chassis with an independent suspension system and differential locks in each wheel, the all-wheel-drive vehicle is designed to be mobile beyond the paved roads, in severe off-road conditions, and wherever the operation takes place. The vehicle is powered by a 6-cylinder 4-stroke Diesel engine coupled to a six-speed transmission. It can run at a maximum speed of 100 km/h with a maximum cruising range of 700 km.

The SISU GTP can be protected according to operation-specific requirements. Due to the modular structure, the protection level can be increased with an additional add-on kit or replacement components. The crew survivability is based on the knowledge and experiences gained from a long history of armored vehicle deliveries for the harshest operational duties.

The ADDER is Remote Weapon Station (RWS) fully developed and designed by the company ST Engineering of Singapore. Lightweight and stabilized for better accuracy, the ADDER range of RWS can be mounted on tracked or wheeled armored fighting or logistics vehicles. Remotely operated below deck or from a control console, the ADDER provides protection for the operator as it is operated below deck. The ADDER range includes variants mounted with various weapon combinations to meet different user needs.

The ADDER is a family of RWS which are fully stabilized and equipped with Day and uncooled thermal imaging system as well as a video tracker. The turret has a traverse of 360° and elevation from -10° to +60°. The RWS i available in different configurations and can be armed with machine guns, a 40 mm automatic grenade launcher, and MK44 30mm automatic cannon.
