Lone survivor 2

After reading up to page 88 in the book Lone Survivor I have realized that the main character Marcus Luttrell is a very experienced fighter with the Navy SEALs.  Since he was a young boy he was working on the ranch and his dad taught him various skills, such as long range aim, swimming, underwater combat, combat, strength and other things.  Also Marcus and his brother Morgan went to this guy that trains people with brutal styles.  He had the group of guys run down the side of a highway with blocks attached to feet.  It was said that because of this Special Forces guy training Marcus and his brother Morgan and their dad training them that they were the best of the best, the cream of the pack, you could say they were the brightest bulb in the bunch.  Also because of their dad training it was said that Marcus could hit a flying can half mile away.  At this point in the book Marcus and his team have landed just outside Afghanistan and are preparing for another flight to another base for warfare and they are trying to gain Intel on the whereabouts of al-Qaeda and Taliban fighters/ terrorists.
