Detonator Droid

'''“Detonator droids explode on contact! Drop them near unsuspecting enemy units.”'''

Information
"Rolling smart bomb that explodes when within range."

The Detonator Droid is a speedy bomb on wheels. It self-destructs when it attacks, making it a one-use unit, but the explosion is pretty potent.

It's very fast, so to take it out you need to either sacrifice some units, bring a lot of firepower, or use Gunships which are out of its reach.
