The Chimera is the primary armoured infantry transport for the Allies and the Imperialists. Highly durable and practical it has been used as a chassis for many other vehicles and has been in service for many thousands of years, typifying the fast moving warfare favoured by the Imperium of Man. The primary duty of the Chimera is to accompany tanks into battle and provide protection for the soldiers within so that they may support the tanks. Standard doctrine states that after the Chimera reaches its objective it lays down covering fire with its heavy weapons while the squad within disembarks and advances. The Chimera then falls back to a firing position from which it can still support the infantry and await orders to race forward and collect the squad again to reposition them.
