Overview
Firing special drill shells, this modified interwar era M7 Priest can keep up with light tanks and fire off special, lethally accurate shells that bury themselves into targets before detonating. While the relatively small amount of explosive filler is poor against structures, they are highly dangerous to vehicles in particular

History

During the Interwar era, Aquilan Army observers realized that they would need a self-propelled artillery vehicle with sufficient firepower to support armored operations. Lessons learned with half-tracks (such as the T19 Howitzer Motor Carriage (HMC) with a 105 mm howitzer on the M3 Half-track chassis) also showed that this vehicle would have to be armored and fully tracked. It was decided to use the M3 Lee chassis as the basis for this new vehicle design, named T32. The pilot vehicles used the M3 chassis with an open-topped superstructure, mounting an M2A1 105 mm howitzer, with a machine-gun added after trials.
