A motorized field artillery or anti-tank gun. The difference between it and a [[tank]] is that the latter is a versatile support vehicle designed to help infantry, while a self-propelled gun is a mobile gun with a single purpose. A tank destroyer is technically a self-propelled gun but because of the similarity to a normal tank, they tend to be grouped under tanks.

Anti-tank self-propelled guns generally have the [[turretless_tank|gun mounted to the chassis itself]] (like the German Stug/Stuh or Russian SU-series of guns). Artillery pieces are more varied in design and can have a turret or an exposed cannon. 

This only applies to artillery pieces with a cannon; mobile rocket launchers are not covered by this term.
