Cool stuff, thanks!
She is Army, something to do with Nuclear Ops, and due to weird timing has seen very little combat. She often says she has patch envy. I like the idea of the officer’s oath. Do you think she’ll get alot of stuff like that?
By "patch envy", she probably means that she has no deployment patch on her right arm, so everybody knows the good Colonel has never deployed.
The one thing I’d say that if she missed her time in the “chit” I would avoid buying gifts that imply combat time. I would also avoid jewelry, like rings, because that’s something that many other people might think of giving.
I like the idea of an inscribed weapon, if that’s something she’d like and appreciate. In her case you might consider another idea, like getting a nice wood-stock, lever action rifle and having someone carve out circular areas on both sides of the stock where you can have her unit and command coins inserted.
