A test video of an unknown combat module on the E501TB chassis appeared on the Web. Experts disagree: some believe that this is AU-220М "Baikal", while others are confident that it is ZAK-57 in the video. We are inclined to believe that the newest Russian module AU-220M is captured on the frames.
Anyway, the gun of the uninhabited module demonstrates excellent shooting accuracy and very acceptable recoil. The very same platform goes perfectly on the snow-covered virgin soil and perfectly overcomes obstacles. But its main feature is different - the module is completely uninhabited and is remotely controlled.
