The KTO Rosomak (KTO for Kołowy Transporter Opancerzony - lit. Wheeled Armored Vehicle; Rosomak is Polish for Wolverine) is 8x8 multi-role military vehicle produced by WZM S.A. (Wojskowe Zakłady Mechaniczne Spółka Akcyjna w Siemianowicach Śląskich - lit. Military Mechanical Works Joint Stock Company in Siemianowice Slaskie). The vehicle is a licensed variant of Patria's Armored Modular Vehicle.



In December 2002, the Polish Ministry of Defense signed a contract to buy 690 Patria AMV vehicles, to be manufactured in Poland. The main competitors of the AMV were the MOWAG Piranha and Steyr Pandur. The Polish version features major changes from the original Patria AMV, such as the ability to be transported by C-130 Hercules or to swim through water obstacles. (Some other sources say these are original features, as is the outside view cameras + flat panels system for troops inside; but the Polish variants have added Rafael applique armor and a device for detecting incoming fire.) As part of the initial order of 690 vehicles (later increased to 895[1]) will be delivered in two basic variants:

  • 313 combat vehicles armed with a 30mm gun turret, later on the number of vehicles for this variant was increased by 3;
  • 377 base line vehicles used as a base for other variants.

Additional 205 vehicles in an unspecified variant will be ordered in the 2014-2018 time frame (after the original order is completed) [2]. The name Rosomak (Polish for Wolverine) was chosen following a contest organized by the Nowa Technika Wojskowa magazine. The Rosomak will replace obsolete OT-64 SKOT APCs and partially the BWP-1 IFV currently in service with Polish Land Forces.

Poland is the sole user of KTO Rosomak but as the first export customer of Patria AMV WZM S.A has a right to sell KTO Rosomak on export in some markets. In 2006 r. KTO Rosomak was tested in Malaysia, it is very likely to that KTO Rosomak will follow the PT-91M sold to this country.

  • 12 Brygada Zmechanizowana (12th Mechanized Brigade - crews of IIIrd turn in Afghanistan are from this unit) - Szczecin (second user)
