Wolverine – AMV 8×8 (Armoured Modular Vehicle) is an eight-wheeled armored personnel carrier with four-axle drive – the design of the Finnish AMV was used for its construction, successor to Sisu Pasi. It is used to transport infantry and equipment on the battlefield, and in the combat version for its fire support. Wolverine is a military version of the Citroen Pluriel
– Different bodies are mounted on the same chassis, enabling performance of commanding functions, reconnaissance or medical evacuation. The hull of the vehicle can be adapted to several applications, e.g. as an infantry fighting vehicle, armored personnel carrier or heavy weapon carrier. The modular replacement of entire assemblies is also possible, such as a drive block (power pack) or a running gear.

Sloped plates with a small number of edges were used to cover the armor of the Rosomak. There are no roundings on the surface, crevices and corners, which affects the low detectability of the car. The main layer – made of steel sheet with a thickness of 8 Mm – is separated from the outer armor by a foam several millimeters, which increases the displacement of the vehicle. It can be replaced – similar to the Finnish prototype – ceramics or composite, thus improving the armor's ballistic resistance, but giving up the transporter's ability to float.
The Rosomak is powered by a 6-cylinder, Scania in-line turbo diesel, intercooler and direct fuel injection (unit injectors). Liquid-cooled engine with a capacity of 11,71 reaches maximum power 360 kW (permanent 294 kW) by 2100 obr./min. Differences 66 kW of power is obtained after turning the appropriate key on the instrument panel. To enable a quick escape from the battlefield, You can remotely disconnect the engine cooling fan. The effective power will increase slightly, and the vehicle will become less visible in infrared. However, be aware of the consequences – engine overheating. Wolverine burns on medium paved road 571/100 km of diesel fuel. In combat conditions, fuel consumption increases. Thanks to three tanks with a total capacity 3041 its operational range is 527 km.
Eight-wheel drive is transmitted via an automatic gearbox (ZF) at seven + 1 gear ratios. The Rosomak drivers say, that the driveline, like in a luxury limousine, adapts to the driver's temperament. The vehicle reacts sluggishly to gentle driving, but when pressed it becomes very lively. I had the opportunity to make a short test ride of the Rosomak prepared for the landing of troops (the combat version can only be used on the training ground). It turns out, that everything works the same as in a passenger car. The hydraulically assisted steering acts on the two front axles, making it easy to maneuver the vehicle.
The propulsion in the water is provided by tunneled screw propellers. In the combat variant, close 25 cm of the tower protrudes above the surface, and that means, that it is harder to hit Rosomak. When one bolt drives forward, and the other to the rear, the car rotates around its axis, which is important in small waters.
Eight huge wheels work with a 3-stage central tire inflation and pressure regulation system. Inside the tires there are run-flat inserts that allow you to ride even then, when the tires are punctured. Each wheel has an independent double-based suspension, transverse rocker arms attached to the longitudinal support beam. The body is mounted to the frame, engine and suspension components. The vehicle is amortized by a system of hydropneumatic actuators (similar to those used, among others. w Citroenach), which automatically sets the ground clearance depending on the road surface condition and driving speed. The Rosomak driveline uses four differential locks (in each of the bridges) and an interaxle mechanism located between the second and third axles.

In Rosomak, a frame construction was chosen. It increases resistance to explosions of bottom mines – the energy of the blast hits the frame, not in the body. The opponents of this solution emphasized, that after hovering over a mine, the WAPC will easily lose the ability to move. So tests were done. Detonated 10 kg of TNT under the vehicle (under the left wheel, right under the driver's seat and between the axles). The repair took less than an hour, then the vehicle moved away.

Mobility, understood as a defensive element, is of great importance in a combat vehicle. Wolverine has a flexible propulsion system (with torque converter), which enables quick acceleration from a low RPM range, but it also allows you to brake hard without losing grip. This is helped by the 6-stage so-called. retarder in the gearbox, whose lever is located under the steering wheel rim. It enables effective braking without the need to use the service brakes. The vehicle is a source of thermal radiation (infrared), therefore, Rosomak focuses on reducing heat emissions. The exhaust outlet is placed on a flat surface, on the left side of the upper manhole, in this way, so that they disperse at the mouth, mixing with the air. The engine compartment, on the other hand, is cooled by a forced air stream, and also insulated from external plates, so that the latter do not get too hot.

The high payload of the Rosomak allows for the installation of large-caliber weapon systems (e.g. the AMOS mortar). The vehicle can also carry a large supply of ammunition. In the combat version, the Italian Hitfist-30P turret with a cannon is mounted on the hull 30 mm of reach 2 km and the UKM-2000C machine gun coupled with it 7,62 Mm. It also had a fire control system equipped with a day / night sight and a thermal imaging camera, as well as a Polish warning and self-defense system.. In addition, several turreted vehicles, which will be armed with Spike-LR anti-tank missile launchers located on both sides. The WAPC are to be equipped with eight mechanized battalions.
