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.

...searching, soul and self...

Wish You Were Here
(Waters, Gilmour)

So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?

Did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
Did you exchange a walk on part in the war for a lead role in a cage?

How I wish, how I wish you were here.
We're just two lost souls swimming in a fish bowl, year after year,
Running over the same old ground.
What have we found?
The same old fears.
Wish you were here...
