"Other armies had different nomenclature, so that a French fusilier was a centre company man and a Prussian fusilier was a light infantryman. "

In Prussia I believe the original (raised by Frederick the Great) 'Fusilier' Regiments were basically 2nd line troops (cheaper to raise and maintain than the Musketeer Regiments), and only later being converted into a 'Light' Infantry role!?!?!?
