The sources I've seen, like
Time, just say she was in DC at the time.
I used to work for Anne Patterson at another embassy. She's a former classmate of Hildabeast. With that said, she wasn't a horrendously bad ambassador, but typically liberal. In fact, she has had some challenging assignments, most notable, Colombia. With that said, I wouldn't give too much credence to the reports until they are confirmed. Patterson isn't a total idiot. Or at least, that was my impression of her.
It would be a stretch to suggest Hildabeast "ordered" Anne to take ammo from the Marines. Hildabeast is smarter than that, and knows she doesn't need to open a fight with the Marine Corps, the later being the reigning Olympic Gold Medalist when dealing with the MSM to form public opinion.
Just my take.
