Judging by the language used, this is an awfully broad definition of "Jessica Lynch Rescuer".
A U.S. Marine who was part of the unit that helped rescue Army Pfc. Jessica Lynch
A Marine who helped in the rescue of Army Pfc. Jessica Lynch
There are probably hundreds (perhaps thousands) of people who fit those definitions. By contrast, it sounds as if the SEAL who was killed was actually part of the rescue team.
I agree with that. That's why my comment questions the number of people considered to be involved with the rescue.
I can see it to be a highlight in an obiturary of anybody, lets say a cook, who happened to be attached to one of these units that rescued Lynch.
