I think my favorite book of all time is "We were invincible" by Denis Morisset and Claude Coulombe.
It talks about the Canadian Special Forces from the point of view of one of its members, who is one of the writers.
Apparently, what is said in the book has been called a lie by our government, which makes it even more interesting to read because it really is realistic and I'm pretty sure most of it is true, regardless of our gov's opinion.
