I believe this is one of the best shows on TV. It appears very realistic from the bond of the characters to their experiences in combat and personal relationships. In the second series I appreciated the show bringing attention to the injuries sustained by these fine men and how difficult it is to get the medical treatment needed, especially for Traumatic Brain Injury. I hope in reality, this kind of attention will help change policies in medical treatment for the better for the men and women who willingly give so much for our freedom.
