Boom Boyz
From Warhammer 40k - Lexicanum
Boom Boyz are Orks who have become obsessed with using explosives.[1]
The deafeningly loud noise, scattering of debris over a wide area and atomization of anyone too close to them, make explosives an irresistible lure to many Orks. They invariably become Tankbustas or vehicle operators.[1]
