Trivia

 * While Auto Tank has been in game, Locked Auto Spin on some of tanks not exist yet, making Auto Tank possible to Rotate it.
 * It's probably the shortest playable Tank in game, making him also most unknown tank by people.
 * The reason why it's removed may be the fact that it's too weak for Tier 4, so creators replaced it with Auto 3 and 5 where Auto 5 is enough strong for Tier 4.
