The anti-tank version of the PARS 4x4 is the latest member of the PARS family of wheeled armored vehicles that was unveiled in May 2015. Developed by FNSS to meet the needs of the Turkish Land Forces Command, the PARS 4x4 Anti-Tank Vehicle (STA) offers both speed and high maneuverability under all-terrain conditions and the ability to engage second targets following a rapid change of position. The PARS 4X4 STA is an exceptional amphibious vehicle that can meet these challenging requirements simultaneously and has been designed to undertake specialized operational roles such as advanced surveillance, anti-tank, and command & control (C2). 

The PARS 4X4 STA is powered by a diesel engine coupled to a fully automatic transmission with an axle lock for use on slippery surfaces and soft soil. The power pack is located at the rear of the vehicle and provides a power-to-weight ratio of 25 hp/ton. The location of the power pack also offers a 180° field-of-view for the driver, who is seated at the front of the vehicle. The vehicle also features additional camera systems for increased situational awareness. There is one single door on each side of the hull. The PARS 4X4 STA has a maximum speed of 110 km/h on asphalt and a range of over 700 km. The engine inlet and exhaust ports are located on top of the vehicle hull, allowing the vehicle to go amphibious without prior preparation, thus granting it the best amphibious capabilities in its class and further enabling The PARS 4x4 STA to maneuver at higher speeds. The vehicle is propelled in the water by two water jets located at the rear of the hull with a maximum water speed of up to 6.5 km/h. 

The PARS 4x4 STA has a length of 5 m, a width of2.6 m, and an overall height of 3.1 m (2.1 m hull).  The PARS 4X4 STA has a low center of gravity, a fully independent suspension system (Double Wishbone, Independent and Helical Spring), ABS-assisted hydraulic disc brakes, low ground pressure, and increased angles of approach and departure (7.5 m Turning Radius), which allows operating on any rough terrain. The PARS 4X4 STA can climb vertical slopes of 70% and can hold on horizontal slopes of 40%. It can also pass over 0.4 m of vertical obstacles and trenches of 0.8m with ease. In addition, the hydraulic recovery winch, located at the front of the vehicle, provides self-recovery when required.

The PARS 4X4 STA features a central tire inflation system (CTIS), which enhances the mobility of the vehicle. It also has run-flat capability thanks to the support ring attached to the wheel that can support the weight of the vehicle in the event of a loss of pressure. The vehicle has a standard crew of 4. The driver’s cabin features a transparent ballistic armor that offers a wide field of view for both the driver and the crew. The PARS 4X4 STA  also provides the driver and the commander with integrated night and day vision cameras that enable night operations with or without using blackout lights. The command and warning panels and the height-adjustable mine-protected seats have been specially developed for the commander, driver, gunner, and the additional dismounted infantry. 

The vehicle is made of a ballistic hull, which provides protection against mines and improvised explosive devices (IED). The vehicle offers a remarkable load-carrying capacity. With its open architecture and significant design, the vehicle can carry out various missions. The PARS 4X4 can be transported using any military transport aircraft, including the CH-47 Chinook heavy-lift helicopter. To reduce operating costs, many parts have been designed to have the same life-expectancy as the vehicle. Thanks to its power pack, which can be removed and installed quickly on the field, the vehicle offers ease of maintenance and logistic support.
