Boros Bomber

The boros have little need for stealth or espionage or even covert operation in general. This is observed best by watching the Bomber Corps they employ in large scale battles.

Boros Bombers are well versed in using explosives, and base their strategy on using them during combat. They prove especially useful against structures and large groups of enemies.
