High Explosive (HE) round: an artillery or mortar projectile containing explosive filler designed to inflict damage through blast and fragmentation effects.
Radar system measuring projectile velocity at muzzle exit.
Artillery or mortar munition equipped with guidance systems to alter its trajectory after firing for increased accuracy.
Artillery system with integrated propulsion, enabling movement under its own power rather than being towed.
Artillery tactic where a firing unit rapidly deploys, fires, and relocates to avoid counter-battery fire.
