Does anyone in the US knows it?

It is a serial TV that tells the adventures of the "Red Troop" SAS team. A LOT of weapons and equipments in action.

Some gunfight are too long and naive for my taste, but you can spend an hour without getting bored.

Yesterday the sat started again to broadcast from the first episode of season one, and I discovered that among the producers there is Chris Ryan, one of the SAS member of the patrol Bravo Two Zero!!!

Not only he was the producer but also he performed in a "cameo" as leader of another SAS team "Blue Troop" on training.

Has this serial ever appeared in USA tv or sat?

Yes.....I just caught it on BBC America. The name sounded cheesy so I didn't really give it a chance.
