I thought it would have been funny if the nametag said Numpty or Bloggins or Doe.
Then I thought it would be fun for kids to just write their name on the nametag, so not every guy in the fight would be named Sperry.
Hammer - you could always hope that you hold a similar fortune in your hands like the original GI Joe prototypes:
"The Hasbro prototypes were originally named "Rocky" (marine/soldier) "Skip" (sailor) and "Ace" (pilot), before the more universal name G.I. Joe was adopted. One of the prototypes would later sell in a Heritage auction in 2003 for $200,001."
I would suggest that they intentionally did not use the proper unit name so as not to avoid legal and financial considerations.
I wish them well perhaps we will see them on a future episode of Dragon's Den.
