She looks kinda young to be a colonel of anything, especially a police agency or a military reserve unit. Maybe she looks younger than she is, but I think the Post got that wrong.
I agree that it is probable the Post got it wrong. No one else -- and I have searched -- has any military rank. It's an anomaly. Unless they document that she's a colonel of something or other, I'm more inclined to trust the eleventy sources that agree than the one that doesn't.
