Due to a lack of equipment, Ukraine devised a plan to recycle Russian equipment.
Ukraine is already running out of equipment only a few weeks after the battle with Russia began. They are compelled to recycle what Russia has left as a result of this. The good news is that most of the Russian military’s equipment is comparable to or identical to that used by Ukrainian forces, so they are acquainted with how it works. Everything they steal from the Russian army is passed to the Ukrainian armed forces, according to Yuri Golodov, deputy commander of one of Ukraine’s Territorial Forces and a former sailor from the Ukrainian Navy.
