LE officers hear this kind of talk all the time. Many of them read a book or heard a story and adapt it as their own. Many were not evan in the service. All of them claim special forces status. Actual special forces people in the armed forces are actually very rare. My son was in Marine Recon. He'll tell you only that he was infantry. Most special forces are like that. They have nothing to prove so why tell you their story. They don't need you to validate their lives.

He attacked you. That is assault. Press charges and get a restraining order. Sue for injury if you want. Also, take the son's stuff away. He thought talking smack posing as you is ok? What if he paralyzed or killed you in a rage fist punch? This is something the kid will stop, now. Take away all this internet capable devices like a phone/laptop/etc. Password protect all devices, Internet, etc, and place passwords in the kids own stuff. And make sure he is NOT authorized to talk to the cable company. I work at a cable company, trust me.

I hope you beat the life out of your kid

I hope you have a serious conversation with your son about the consequences of his actions. He will need to be punished for this as I hope he learns how serious this was. I hope you were ok OP and that the police did catch this man.

Revoke your son's internet privileges.

I hope to god you beat the shit out of your son.

why would your son give him your address...thats like rule #1

Maybe you should try one of those creative punishments and make your son wear a sign saying that he got his dad beat up ... on second though that is probably more embarrassing for you. It's probably best to stick with the conventional ass whooping!

It's one thing to play a video game it's another thing entirely to do something like that FYL and have a serious talk with him.

Press charges against the guy who attacked you, and take away your son's technology, and punish him with other things.
