My Sister Left For Basic Military Training In The Air Force And Things Have Taken A Turn For The Worse.

2 weeks ago my sister left for basic military training in the Air force and 2 hours ago my mom got a call from my sister where she told us that she's being abused. My sister fractured her knee while at training and has been in an immense amount of pain because of it. Despite this her instructor has continued to coerce her into continuing the training exercises at her expense. She has attempted to push through it however, it's no surprise she wasn't able to physically do that given the nature of her injury.

From what she told us, despite the state of her knee continuing to deteriorate (it's now at the point of intense swelling) her instructor has continued to berate her, even going so far as to humiliate her by getting the other recruits to laugh at her for not being able to push through her injury.

She is now sitting in a mental hospital for refusing the orders of her instructor. Is there anything that my mom and I can do for her? This is a nightmare.

edit: I posted this to r/airfroce and I've gotten a lot of comments saying this type of thing is extremely unlikely to happen so I'm going to hold off on doing anything drastic until I can get some more information

Thank you, everyone, for taking the time to provide some insight. At this point, I'm fairly certain that my sis might just be going through nit mentally to the point where she's lying to get out. We're gonna try our best to support her going forward using what I've learned here today, I appreciate you all so much.
