Is this irony?

I was glancing over a copy of the book Stolen Valor: How the Vietnam Generation Was Robbed of its Heroes and its History when it struck me that there is something amiss with the cover.

Can you spot what is wrong with the cover?

Hint: It's the kind of error some of the featured subjects of the book might make...

Q: Is it intentionally ironic?

UPDATE: Upon further examination, it appears there are a couple of mistakes...
