Thank you, ma'am. That's an excellent question.
The onus has always been placed on the injured and ill to advocate for themselves and to navigate a gauntlet of processes for these applications. Documentation sometimes is there from DND but doesn't get transferred over to Veterans Affairs, and often the veterans and/or their caregivers are the ones who are advocating for them.
The processes are extreme. They subject the veterans and their families to sanctuary trauma by having them prove that they are actually ill and injured, when the documentation, for the most part, is there in the file.
