Polaris' RZR side-by-side is one of the most ubiquitous UTVs around the world, and it's understandable why. It's basically the do-everything platform. Just from Polaris alone, you can go mudding, hunting, set it up for fishing or camping excursions, rock crawling, and everyone's favorite, go faster than an F-14 launching off a carrier. It's also basically indestructible.
So it's understandable why militaries around the globe, including our own, have sought out the machines for all their clandestine and out-in-the-open operations in theaters of war or military conflicts. It's also why Polaris has an entire division that's solely focused on government contracts, which also includes the brand's snowmobiles, and a prototype tank.
But Polaris isn't the only one out there modifying its vehicles for combat. There's a whole cottage industry within the military industrial complex space that takes these consumer models and up-fits them with everything and anything soldiers or militaries would need on the battlefield, basically turning them into the modern Toyota Hilux—though, everyone still loves the Hilux.
