Can't Stop The Music!

So I'm a little confused. I just finished watching the 1980 camp classic, Can't Stop The Music about the semi autobiographical rise of The Village People. I have to say I'm a bit perplexed. I know when The Village People were at the height of their fame I was just a youngin'. But I don't recall a Military Man in the group?

There was only five: The Indian, The Leather Man, The Cowboy, The Cop, & the Construction Guy.

Where did Military Man come from?
