I suppose I’m asking both about people who are currently serving as Navy Seals, and the total who have served in that role. The reason I’m asking is, everybody seems to know a Seal or three, but I’ve never heard anybody say “Yeah, my best buddy is a supply clerk with a mechanized infantry division.” The Army is much bigger than the Navy, and the Seals are IIRC only a tiny part of the Navy, so the arithmetic causes me to be a teensy bit skeptical of all the people who seem to know Seals.
(Which raises a tangential question of why the Seals get so much public attention when there are plenty of other special forces units … which raises the question of why special forces gets so much attention when convention forces seem perfectly respectable to me.)
