Many guys get their own gear after being literally crowdfunded. It was especially so at the start of the war, and not just in volunteer formations. (Those delivering the packages to the front were also known as volunteers in English, but the Ukrainian words are different.) Today just like many others around the world (including various Islamists) they for example love to fit themselves with the prized Pulsar thermal sights that you can buy in America for hunting and are just total game changers for night combat and sniping purposes.
