I am trying to imagine how someone would embellish their Navy Electrician Service. The closest thing to heroic would be firefighting & damage control. Nothing that would really sound impressive.
I could talk about how I was really great at completing the PMS on Switch Boards and Load Centers in record time for my ship and the Chiefs really appreciated it to the point of allowing and E4 to run these operations.
A) Only another EM would have a clue what I was talking about.
B) Who on earth, could I impress with a fact like this?
If I started talking out my ass about fighting in Kosovo in the nineties, anyone with Army experience should be able to determine I was full of shit, I would guess that a few questions from people that either knew about military weapons or Kosovo would trip me up quickly. I know my Nephew-In-Law would. He could however spin almost any reasonable tale about his days there and I would be clueless if he was full of shit.
I would not have a good clue what made someone an Army Hero or not, unless they made huge gaffs, like the mentioned ranks.
Once I ran across someone bragging about his service time on the USS Forrestal in Vietnam and several things he said ran very false. He did not know enough about how these carriers were designed for someone that was on flight deck crew. I served on a sister ship of the Forrestal, so I called him out on several pieces of his story. I am guessing that even someone that served on a destroyer would not have known what he was saying was wrong.
