Kannons are heavy bore artillery pieces that fire anti-tank shells or frag rounds for use against enemy infantry. Like all Ork field artillery pieces they are referred to as Big Gunz. Wheeled or towed into position at the back of the Ork lines, Big Gunz are set up in a battery and manned by a team of miserable Grots.

The Kannon is a tough artillery piece, highly detailed and with a characteristic front plate containing metal rivets, bullet holes and a flashy symbol. The Gretchin crew, here in minimal clothing, are sculpted as if they're in the midst of battle, one ready to load up the Kannon with a shell, the other possibly ordering where to shove it.
