Big Gunz are Ork artillery units, commonly crewed by Grotz. They are usually large guns mounted in a cannon-style, wheeled for transport and low to the ground so their Gretchin crews can access them. They are often used in groups and have a single team of grechen crewing up to three of the guns at once under the supervision of a Runtherd.*¹

Common Big Gunz include:

• Lobba
• Zzap Gun
• Kannon
