IPA: /ɑːrˈtɪl.ər.i.mən/
KK: /ɑrˈtɪləriˌmæn/
A soldier who operates large guns and artillery equipment in the military.
The artilleryman skillfully aimed the cannon during the battle.
Artilleryman is formed from "artillery" (from Middle French *artillerie*, meaning equipment for war) and "man" (from Old English *mann*, meaning person). An artilleryman is a person who operates or is involved with military equipment used in warfare.
Think of an 'artillery' as the equipment used in war and 'man' meaning a person — an artilleryman is someone who operates that war equipment.
