Getting an E4 a comm

I've got an absolutely kickass, amazing, stellar E4 who's departing this spring and I want to get her a comm on the way out the door. I don't think I've ever seen an E4 get a comm, usually LoC or an Achievement if they're really good. She'll be departing the unit as a fresh E5, but the award will be written on her performance as an E4.

But, I want to get this one a comm. Any suggestions on how to help make it stick? I'm a pretty decent award writer, but this seems like something I could use some bonus advice on.

Also, for context, we're on a small cutter

(And yes departing awards are dumb but there's not much I can do about that)
