What is the definition of a SPG?

• A. A thinly armored vehicle, that has tracks or wheels, and can provide indirect fire with artillery
• B. A small armored scout vehicle
• C. A self-propelled gun that fires directly at targets
• D. A vehicle that mounts anti-air missiles

Answer: (A)

Self-propelled gun means a gun mounted on a vehicle that can move under its own power and deliver indirect artillery fire. This setup provides fire support from a mobile platform, allowing the gun to reposition and respond quickly while still firing at targets not in direct line of sight. The description of a vehicle with tracks or wheels that can provide indirect artillery fire captures that idea precisely, since the emphasis is on mobility combined with an artillery piece used for indirect fire. The other options describe roles that aren’t SPGs—such as a light armored scout vehicle, a direct-fire gun, or an anti-air missile carrier—so they don’t fit the definition of an SPG.
