the unit that Charles de Batz de Castelmore served in was called Les Mousquetaires du Roi, or the the Musketeers of the king. Charles de Batz de Castlemore served as a captain in the unit during Lois XIII and Dumas roughly based his novels off his exploits.
As an aside, one of the few things the movies gets right about the novel (or even just the period) was the general foppishness of the military culture and upper-classes of the time.
None of them use muskets?
they were the royal guard, its just what they were called. the musket was not really a thing at that time, it was mostly called a arquebus
