''Damn , do u know how heavy those tracks are ?''

Poor Jagdpanther-chan.

She doesn't have an official name, but she has been dubbed a name by pixiv artists and fans. In fact, the artist used the tag there for this picture.

履帯子　--> りたいこ --> Ritaiko.

履帯 ritai is used exclusively for "tank treads" and 子 ko (literally meaning "child") is a common ending for girl's names.

If someone more experienced than I feels a character tag is justified?
