I have only recently converted to "Napoleonic" warfare and I'm currently reading "The Army of Frederick the Great" by Christopher Duffy. So, forgive me if my following question is "noobish".
Is there a difference between Fusilliers and Musketeers? Wikipedia claims that "Fusilier was originally the name of a soldier armed with a light flintlock musket called the fusil. The word was first used around 1680, and has later developed into a regimental designation."
So, I wonder: is there a practical difference between a musketeer and a fusillier in the 18th century and onwards? Or was it just a "name-thing" and were both types of soldiers equipped the same way?
