Anyone (Man or woman) who is not willing to risk (Not give up - risk.) their life in combat does not belong in the U.S. Military You don't go to war intending to give your life, you want to make those poor basteges on the other side give their lifes. But you have to be prepared to give your life in defense of the USA if that becomes necessary. Not everyone comes home alive.
Here is one line from The Code of the United States Fighting Force:
"2. Code of Conduct I a. I am an American fighting in the forces which guard my country and our way of life. I am prepared to give my life in their defense.
See the entire code here: Code of the United States Fighting Force - Wikipedia, the free encyclopedia
This code has changed a little since I memorized it back in 1961, mainly to make it gender neutral.
Have a good day.
