@Soldierofmisfortune: Yes. Fox Company's first platoon, second squad would be "Fox 1-2." Further identification is given as a specification as to whether the individual is enlisted, their grade, and the first letter of their last name. I'm a Corporal, whose last name begins with "D", so I'd be "Echo Four Delta."
