Allstate guy is Dennis Haysbert, and The Unit was an amazing series. It basically revolves around the new guy joining said Unit, and the adventures they have after he gets in.
I recall a couple of times that they went outside the realm of actually possible/plausible but for the most part, they get the military aspect right, and that's something I dislike about so many shows - just how fucked up they get military protocol, and procedures. If I'm not mistaken it was written by an actual team member after he retired, so he knew what he was talking about.
I highly recommend The Unit, and it's only 4 seasons long, so you can watch it in a couple of days if you marathon it.
