This the Hen Long is a 1:16 scale model quality model tank. This is an upgraded version of this tank that has metal tracks and drive sprockets. It is missing a road wheel with can be replaced from ordering a kit on this platform. It also needs an accessory pack for some of the cosmetic details. This will come with a remote battery and inferred sensor for competing with other tank models. It worked that last time it was used but has not been used in a while just kept in the garage. These tanks are very much modifiable and parts can be found fairly easily especially on eBay.
