Fusileers? yes that was the original spelling when such troops were formed.

From the french. Using the 'Fusil' A light flintlock musket.
muskets being in use in the period covering the french indian wars and seven years war.
Such a shock to some in loading a musket when they're used to
CSGO or arma3.. but it makes for combat at its most personal.
Melee fight are frantic and bloody after the first shots. Arrows flying in, sword against tomahawk and fists and boots when weapons are scarce.
Hard to say whats more fun. Firing at regulars from cover or chasing them as indians, whooping and screaming shooting them full of arrows. But no US cavalry charging in to save them.
