There are so many fake posers out there now. There is web site (can't remember the name) run by ex Navy Seals who have access via the Navy to all the true graduated names of Seal school, and if two separate people contact them with their suspicion that someone is falsely claiming to have been a seal, they will investigate, and if indeed it is a poser, they will personally go and confront him.
There was a Marine poser on another web site who was claiming purple heart, Viet Nam covert duty, Federal agent career and all his stories didn't add up. I started asking him questions and he never would provide any credible verification. Claimed to be all down on his luck and broke after a supposed combined 38 yrs of military and federal agent service. Claimed his former Treasury agent "partner" had been gunned down in a Target store (shot in the back 5 times).
Then I searched his user name (Alec411), and found other weird posts by him elsewhere. Claimed that he had been a military advisor to two Presidents, POW, etc, etc.
He disappeared from the web site after that.
