No, there wouldn't be a way for them to know what's available, especially if they don't have access to representation or any legal information. Unless they were told, they would not know that they have the right to have access to a victim liaison officer. That would be left to the discretion of whom? Would it be the SMRC, the chain of command?
The thing is, most of the people affected by these things are very young. They are people who just came into the military and they don't have much knowledge. Most of the people I've seen who are impacted by sexual violence don't have the necessary knowledge, yet they may have been in for six months or more. It's overwhelming to navigate and find anything, and most of them don't have access to the DWAN account, which is the intranet. Even if it is on the intranet, they wouldn't even know where to look.
