When attempting to administer aid to downed players, they can often fall into awkward positions, making bandaging limbs or sometimes the chest impossible as the main casualty menu has priority:

I suggest adding an option to this casualty menu to roll the character onto their back (Like the Push/Pull option for rolled vehicles) like this:

Here, all four limbs and the chest are easily reached, and is an existing animation/model state.

This would make administering aid significantly easier, avoiding clunky UI conflicts while maintaining realism and avoiding uncessecary KIA because team mates are unable to help.
