Just to provide a slightly different perspective on this. When I was working at a reserve unit, there was a mbr who came back from overseas with some serious mental health issues. The unit tried its best to help this member but he stopped showing up and returning calls. Eventually, they just had to admit that he didn't want help and there was nothing more than can do but be available. In the regular force, we can order a mbr to get treatment, what ever the problem. In the reserves, they have no such hold on these people.
Another issue I had to deal with was the fact that reservists are most likely to get injured while away on training. Often their supervisors are reservists or augmentees for summer training. Combine this with people still not doing CF98s, and 663s, and you have a paperwork nightmare trying to get the reservist the proper care and/or compensation. I had one situation which had me sending emails all across LFWA looking for people to give statements and it took months to sort it out. Luckily, I was available to do this most reserve units don't have the personnel to run with this stuff for weeks on end.
The plain fact is Reservists are much harder to deal with when it comes to health care. The is no easy solution. I like to think that most people have the right intentions but it is very easy for people to fall through the cracks.
