If anyone is looking for a good book to read, pick up "Lone Survivor: The Eyewitness Account of Operation Redwing and the Lost Heroes of SEAL Team 10".
I'm about a third of the way through it and it is very well written. There is a lot of background on the training they go through. I haven't even gotten to the event in Afghanistan yet. I can't even begin to fathom the training they go through.
Thank you to all who serve. And that seems so minor for the sacrifices they make but thank you.
