US was one of the founding members of the Metre Convention that set it as the international standard
It’s amusing to realize that United States customary units are defined in terms of metric units.
I'm afraid you might be thinking of a super foot, soldier.
(Edit: I had a brain fart and wrote foot instead of yard, but thankfully the next commenter saved it)
And three times better than a super foot is a super yard. 3 times better than that is a super freedomball field.
implying we don't have liberty-loving democratic super meters lol. Might want to check again.
Helldiver gear just still displays the old metric super foot. Crewman and techs are too busy muzzle loading the deck guns to be updating each and every trooper's HUD.
