That's the game's internal name for the ANT. More or less Which makes me wonder: What would the Ant be like if its weapon were a laser, of the same type seen on laser turrets and the scout aircraft? How would you react to that change? The Leveler is labeled "tank_laser_adv" too, so there's that.
Considering that tank shells might as well be lasers because of how fast they travel... If you're going to reduce the range of a main battle tank from 2km to a few meters, reduce the travel speed of the shell too! You can't scale down one without having the other look out of place.
