AT70 Reaver Battle Tank
The AT70 was considered an inferior design compared to the standard tank of the Imperium, the Leman Russ Battle Tank. The tank lacked any Auspex or laser rangefinding equipment, requiring the gunner to aim by visual methods only. It also lacked any gyro stabilizers, limiting its ability to hit targets while moving. The AT70 was armed with a hull-mounted lascannon and a 105mm hypervelocity main gun, which had a slow rate of fire and was unable to penetrate the side armour of a Leman Russ. Due to their inferior quality, Reavers were only a threat to Imperial armoured forces when they outnumbered them.
When the forces of Chaos captured Urdesh during the middle of the Sabbat Worlds Crusade, many Urdeshi-designed weapons and vehicles were produced in great numbers to equip their forces, including Reavers. Among those who used the tanks was the Blood Pact, which was often engaged in heavy fighting with Imperial forces, especially against the Tanith First and Only led by Colonel-Commissar Ibram Gaunt. With the recapture of Urdesh by Imperial forces, use of the AT70 by the Blood Pact would eventually decline.
