IED

IED is a tier 5 tank that upgrades from Catapult at level 60.

Design
It has a light blue barrel that resembles the barrel of a Destroyer or Pounder turret, with a slightly larger and shorter turret below. This light blue color is rare on tanks, looking similar to the color of Comet that can also be seen on Bar.

Technical
The tank has a barrel shoots a silvery bit (meant to resemble an old glitchy Nokia phone) that explodes after a while. The explosions start large and shrink quickly, an inversion of how Shrapnel or Zeppelin explosions work.

Upgrades
IED upgrades from Catapult at level 60 and doesn't upgrade to anything because it's tier 5.
