rifleman

n. gunman, person who shoots with a rifle; soldier with a rifle, carbineer

Rifleman is a private soldier in a rifle unit of infantry.Originating with the 16th century handgunners and the 17th century musketeers and streltsy, special units equipped more modernly than the bulk of the pikemen, the rifleman from the 18th century has become the archetypical common soldier. The last pike regiments were dissolved by the 1720s, and the bayonet in some ways replaced the pike, some commanders ordering concentrated close-range bayonet attacks until the early 20th century, often with devastating effects for their own troops.
