How can a sergeant major (Roadblock) be second in command ...
... when under the captain (Duke) they have a first lieutenant (Lady Jaye)? I know that in the comic/cartoon version she's a staff sergeant, but not in this movie version.
I don't know much about the U.S. military (or any military) chain of command, obviously, but to a layperson that doesn't make much sense.
Could anyone shed some light on this? Thanks.
