During the rout of the Russians in Karkiv Oblast about a month ago one of the you tube news videos showed the Ukrainians fabricating or modifying similar dune buggies. Apparently, once behind Russian front lines, the vehicles' speed and mobility allowed them to wreak havoc in the rear areas.
great BBC newsreel. Ukrainians are resisting & overtaking their (our) enemy against all odds. Hope the US realizes the importance of our aid & hope we continue to assist their effort as long as necessary
