shellproof
Withstands artillery fire
Shellproof means resistant to damage from artillery shells or explosive projectiles.
The term describes fortifications, bunkers, or shelters designed to withstand bombardment: The troops retreated to a shellproof dugout.
Like bulletproof and bombproof, it indicates protection against a specific threat rather than invulnerability.
