I thought Stormtroopers, in Star Wars, got that name from their WW1 cousins?
https://en.m.wikipedia.org/wiki/SturmabteilungVery specifically part of the Nazi Party. EDIT: Only had a second to browse at work, which left me fairly wrong here. Further reading shows you're right that the term originated in WW1. The Nazi's "stormtroopers" served as a paramilitary group backing the Nazis and were highly influential in the rise of the Nazi party, but when the Nazis took over the govt., the SA made the political mistake of attempting to fold the German army into its ranks. The SS was partly created to serve as a control over the SA, and personal/class/ideological differences between the two caused tension as well. Eventually Hitler was convinced to arrest and slaughter the leadership of the SA in a Red Wedding-style move, though it continued to serve as an anti-Jewish group doing horrible things, and by WW2's start much of it had been folded into the Wehrmacht (the official military).
That said, the use of it in Star Wars was an intentional link to the Nazis.

While I don't mind the idea of giving back take cover to infantry, I just don't think they need it - they are already by far the most cost-effective ground unit (even moreso if you have Wayland), and the only real counter to massed infantry is a lot of artillery or other AoEs.
