jmo but I'd use the other in-service stressors. My feeling is the VA adjudicator will feel/say "your brother died, live w/it." We all lose family, friends, etc., so it's not out of the normal range of events. You weren't there, you didn't witness his drowning, so I don't feel it would reach a stressor level. On the other hand, as a firefighter, responding to MV accidents, aircraft(a/c) crashes or potential a/c crashes, drownings or possible drownings, I feel they would qualify better. As a former firefighter/emt, myself, I can remember the things going thru my mind responding to an event. You must be prepared for everything and the adrenaline in your bloodstream had you so hyped, that you couldn't start to calm down until you'd done your own assessment or had a conformation of whatever the event is. Check the VA's PTSD criteria for stressors for the period you were in the service. I believe you need to have witnessed or feared the loss of life, yours or someone else's, or something along that line. I believe, a brother dying doesn't cut it. Sorry you lost him!!
