A World War I German Musketeer?

In the last entry, I mentioned one of the buried Germans as being Musketeer Martin Heidrich, 21. I was unfamiliar with Musketeer being used for German soldiers as late as 1918. I knew that soldiers up until the 1850s-1860s used muskets as a main personal weapon, so the term Musketeer would make sense.

However, by the Civil War, the use of rifles became more the weapon of choice. Hence, the term rifleman.

According to Wikipedia, the term Musketeer is the traditional designation of an infantry private. The use of Musketeer survived in the Imperial German Army until World War I, which would explain Musketeer Heidrich. However, there was a private also buried in that tunnel.
