I think the charge is that she had her rib broken doing combat training prior to the march. Those things do happen and it would be completely different from being kicked after passing out.
I spent 8 years in the Navy, 4 of those attached to the Marines. I seen rough training, I’ve seen people yelled at. I’ve seen people yelling things that in other contexts would be considered threats. I’ve never seen a sailor or marine kicked while they were down.
When someone goes down during a march, in every instance I’ve witnessed, fellow marines have rushed to their aid and a corpsman was called for. Aid is given and transport for further care is given if required.
The Marines are very sensitive to the health of their men (gender neutral). I would assume the Army is similar in this regard.
The grandmother “knowing” about a broken rib that punctured her heart is rather suspicious.
According to the article, she was kicked prior to the march. Also, since she is not in basic training (and the DIs aren't allowed to do that anymore), she wouldn't have been kicked by anyone in authority.
It is not that hot here this time of year. In fact it is quite cool.
