Brief History - from Wikipedia
The first Kozak vehicle (also known as Kozak-1) first appeared on August 24, 2009 at the Independence Day of Ukraine military parade in Kyiv. Only two vehicles were manufactured prior to March 2014.
The third vehicle (also known as "Kozak-2014") was built in November 2014 and was intended to be a proof of concept to address a growing requirement for a mobile MRAP. In March 2015 the vehicle was armed with the NSV machine gun.
Another variant, the Kozak-2, was built in 2015 and armed with an anti-tank guided missile system. In May 2015 the vehicle appeared at the 169th Training Centre.
