Which of the following is NOT listed as a filler used in artillery ammunition?

• A. High Explosive (HE)
• B. Chemical
• C. Submunitions
• D. Armor-Piercing

Answer: (D)

Fillers are the substances inside artillery projectiles that create the intended effect on target. High Explosive is a filler because it detonates to produce a blast and fragmentation. Chemical is also a filler, delivering toxic or other agents inside the shell. Submunitions act as the payload inside certain munitions, dispersing many smaller effects when the shell opens. Armor-Piercing is not a filler. It describes a projectile designed to penetrate armor, usually with a solid or very dense core and little to no explosive filling. If an armor-piercing round has an explosive, it’s a different designation (like APHE), not simply a filler category.
