Isn't there something (called Stolen valor or something) that arrests or files criminal charges to these kinds of fakers ?

It seems though that this only prosecutes those that falsely wear a medal and not those just claiming to be part of a special military unit.
From your link it sounds like it's a federal misdemeanor to falsely represent oneself as having received any U.S. military decoration or medal. I would hope impersonating or claiming to be part of an elite unit is also a punishable offense but I don't know.
Check this fake out, previously in the Air Force. Spent over 4 years at Pope AFB as a loadmaster on C-130s and reached Airman First Class (A1C...E-3) before being court-martialed for multiple counts of drug use with bust to E-1 and BCD in 2005. Surprised he didn't get a dishonorable discharge.
Story is he went to Ft Benning for a graduation of a family member when the MPs detained him. Apparently all that drug use affected his judgment...when confronted, he said he knew he went overboard but didn't think the Army guys would know anything about an AF uniform! Wrong...when you blouse a Class A uniform with desert boots and a beret, displaying a CIB, Master Parachutist Badge, Air Assault Badge, and all of that other stuff, even an idiot would take notice.
This dude has more medals than Audie Murphy had...what a complete idiot. I recognize a lot of those medals and citations at a quick look and any old timer would immediately know this guy is far too young for some of those. Dude went high order to boot...DFC, Silver Star, BSM, Vietnam (RVN) Gallantry Cross, Purple Heart and on and on, and he proudly displays that rank he didn't earn. Looks like he went into the military clothing store and bought one of everything they had!
