The true warrior must take responsibility for his or her entire world.  The whole world. 

And as in the world, thus also within.
Tat svam asi--That is thyself.

Thus is the war first waged in the heart and soul of the warrior, the interior-cosm, reflecting the cosmos itself.

Consequently, the warrior who conquers himself/herself has already achieved a victory comparable to conquering a thousand of the enemy upon the battlefield.

Conquer thyself and awaken to proclaim "Hoka Hey!  Today is a good day to die."
      Crazy Horse, chief of the Oglala Sioux

Weapons are tools of violence,
Not of the sage;
He uses them only when there is no choice,
And then calmly, and with tact,
For he finds no beauty in them.

Whoever finds beauty in weapons
Delights in the slaughter of men;
And who delights in slaughter
Cannot content himself with peace.

So slaughters must be mourned
And conquest celebrated with a funeral.

    Tao Te Ching, Chapter 31

The true warrior is forever unknown.  And all the awards and medals for heroism and valour bestowed thereafter are but beads on a baby's bracelet.
