Even if the numbers are half---this is still a big deal. It essentially is a 2X multiplier in net numbers since Russia is out one and Ukraine is up one

“Repurposed captured Russian equipment now makes up a large proportion of Ukraine’s military hardware,” the report from the U.K.’s defense ministry said. “Ukraine has likely captured at least 440 Russian Main Battle Tanks, and around 650 other armored vehicles since the invasion. Over half of Ukraine’s currently fielded tank fleet potentially consists of captured vehicles.”

“The failure of Russian crews to destroy intact equipment before withdrawing or surrendering highlights their poor state of training and low levels of battle discipline,” the report added.
