If you ever watch Future Weapons (with Mack!) on Discovery we really are getting the Starship Troopers phase. Not sure if that's a good or bad thing
Hammered home by the 1997 concept art for Starship troopers that is now science fact:
Powered armor first appeared in 1937 in the Lensman series, and was re-popularized in 1959's "Starship Troopers".
Do those have jump jets and tactical nukes?
