Plural of artillery; multiple collections of large guns, cannons, or military weapons; or multiple artillery units.
From 'artillery' + plural '-ies'. The word 'artillery' itself derives from Old French 'artillerie' (equipment, gear), ultimately from Latin 'ars' (art, skill).
The word 'artillery' originally meant any military equipment or supplies—it only narrowed to mean cannons as those weapons became the dominant force in warfare, showing how technical terms follow military evolution.
