Kill Tanks
The Ork Kill Tanks are a family of Heavy Tanks developed by the Orks to compete with the likes of the Imperium Malcadors in both killiness and dakka. Each of these vehicles are a tough nut to crack and have specialized weaponry designed to either shred infantry like paper or demolish fortifications like they aren't even there. They are split between the Kill Blasta, Kill Bursta and Kill Krusha.
Kill Blasta
The Kill Blasta is the one specializing in anti-infantry warfare. Armed with a imposing array of Big Shootas, Rattler Kannons, and rapid-firing Kannons, collectively referred to as the Giga Shootas. These tanks are unfortunately forward mounted like the Kill Bursta and must thus move the entire vehicle to fire from a different angle.
Kill Bursta
The Kill Bursta swaps the array of Big Shootas, Rattler Kannons and rapid-firing Kannons for a single huge hull-mounted Kannon capable of destroying bunkers, buildings, or fortified positions with ease. Again the static kannon means the entire vehicle must move in order to aim and fire a single shot.
Kill Krusha
Unlike its previous brethren that has a static forward mounted kannon. The Kill Krusha is a full front line battle tanks with a semi-turreted Krusha kannon that can fire a range of specialized rounds such as the standard high-explosive "Boom" shot, the armour piercing "Tankhammas", the anti-infantry shrapnel "Scrap Kanisters" and the incendiary "Blast Burnas". The Kill Krusha also has two sponson mounted Big Shootas commanded by two Gretchins, the sponsons can be replaced with Skorchas or a Rokkit Launcha. Apparently these Kill Krushas are all tended by a horde of numerous Grots who keep the rattling monster tank going with constant hammer blows, polishing and judicious application of oiler squigs.
However there are issues. One of which is due to the complexity (By Ork standards) of the auto-loader gubbins and thus, do not always work as they should. There are sometimes jams from mechanical failure, or the Grots get caught in the gears. Othertimes the Grots load the wrong shell. The worst possible failure would be the shell being fitted in backwards, causing it to simply go off inside the tank and causing horrendous damage.
