Dropper

 is a Tier 5 Tank that upgrades from Bomber and Flank Builder at level 60.

Design
The looks pretty much identical to Bomber but it has a Builder turret replacing its rear trapper. Its thrusters are not moved to accommodate it so it is simply layered above them. It can also be described as a Flank Builder with Bomber's thrusters attached to it.

Technical
Like the Flank Builder, its blocks move towards its mouse giving it surprising offensive power for a Bomber branch.
