Armoured anti-air unit.
The roar of Mek Gunz has heralded the end for many a hapless foe. Spitting out blasts of crackling energy, swatting planes out of the air or crushing their victims in crackling fists of bright green force, these big, clanky field guns have enough dakka to stomp even the toughest targets. Of course, as no self-respecting Ork would be left behind when there's a fight in the offing, crewing the gunz is left to the long-suffering grots.
