Seems likely she was mad about something right then and lashed out. It was like 2 in the afternoon her time when she sent it.

Hey Gurka - Is she in her OBC class now?

Nothing like getting a message between classes that might go something like this...

"Mrs. LT Gurka, please report to the commander at 1900hrs this evening"

Yeah, I'm speculating, but the investigation should be winding up pretty soon. I suspect that you'll be hearing from her once it's over, especially if she finds out that she's getting booted out of the army...

Semper Fi,
