Rocket-Copter

 is a Tier 5 Tank that upgrades from Dirigible at level 60.

Design
The looks identical to the Dirigible but it has two Smasher-shell gray trapezoids to either side of it, similar to those employed by the Demolition Mecha. These may have been mounted on "stilts" to connect them to the body.

Technical
Its gray trapezoids are actually rocket launchers that fire missiles similar to the RPG's. They fire on altfire, while mainfire only controls the central gun.
