Bm                      Em
All I saw was smoke and fire
               D
I didnt feel a thing
A                  G
But suddenly I was rising higher
Bm                     Em                  D
And I felt like I just made, the biggest mistake
       A                       Em
When I thought about my unborn child

                        A                         Em
When I thought about my wife, the answer rang out clear,
                   A
from somewhere up above
                   Em                                 G
No greater gift of man, than to lay down his life for love

G  D
      And I wonder,
A               D     G D
would I give my life,
A                  D          G D
Could I make that sacrifice
A                             D                    G
When it came down to it could I take just a little blood,
      A
Yes I would for you.

Bm                  Em
Baby you dont understand,
                          D
I dont understand it all myself,
              A                        G
But theres a brother on my left, and another on my right.
Bm                           Em
And in his pockets just like mine,
                 D         A                          G
Hes got a photograph, and theyre waiting for him back home.

                        A
And its weighing on my mind.
                     Em                    A
I dont want to be a hero, I don’t want to die,
                      Em                      G
But right here in the moment, you dont think twice.

G  D
      And I wonder,
A               D     G D
would I give my life,
A                   D         G D
Could I make that sacrifice
A                             D                    G
When it came down to it could I take just a little blood,
      A
Yes I would for you.

A                            Em
You dont think about right.
                             A
You dont think about wrong.
                           Em                D
You just do what you gotta do to defend your own.
A                       Em    D
And I would do the same, for you.
