My european brain could not handle why this would be the way to treat a pregnant person until I realized, that this might be about a weapon instead of a child.

The context might make this obvious for people who are more used to guns than babies, but I was very confused.

They kept shooting at her even when she was limping away crying and someone trying to help her. So being a threat I think was the least of their concerns. Seems more like they were enjoying target practice.
