Another Battletech vehicle that was commissioned at the same time as the Horiato Bridgelayer.
The Mastodon uses the flail minesweeper to detonate mines as it drives along, a method thats been in use since WW2. Mr. Satak's project involved two combat engineering vehicles, both of which seem to not be of any interest to the other artists( I guess they weren't as "glamorious" as the mecha or combat vehicles)...so the Artraccoon took a stab at them.
In reality there should be a whole lot more dust and debris flying about, but the vehicle would then be mostly obscrured. The tank is armed with large laser and a small laser cannon.
