Hammerhead

Album version of Hammerhead by The Offspring.
If you see chords written like this: G(Em), it means that you can play Em or G and it won't really differ.
I left them as a variable as I couldn't decide which chord sounds closer to the original.
I also used this (https://www.youtube.com/watch?v=23pAKuU-apw) instrumental version to clear up some points.

[Intro]
Em x12
Em D x8

[Verse 1]
G
I am the one
G
Camouflage and guns
G
Risk my life
                       Em D  Em D  Em D  Em D
To keep my people from harm
G
Authority vested in me
G
I sacrifice
                    Em D  Em D
With my brothers in arms

[Pre-Chorus]
Am           D(C)
Through this doorway
       Em
What's on the other side
Am    D(C)
Never knowing
  Em
Exactly what I'll find
Am
Locked and loaded
                       D
Voices screaming, let's go
G       D              Em
Come on do it, here we go

[Chorus]
     C                       G
I'll take a life, ten others may live
D                          Em
Oh, that's just the way it goes
     C                        G
I'll shut my eyes, it hammers in my head
D                      Em
Where it'll end nobody knows
     C                       G
I'll take a life, ten others may live
D                          Em
Oh, that's just the way it goes
             C             G
It's playing over and over in my head
D                      Em
Where it'll end nobody knows

[Instrumental]
Em D x4

[Verse 2]
G
Stay the course, reasonable force
                            Em D  Em D  Em D  Em D
I believe I serve a greater good
G
Smoke and dust, enemies are crushed
                               Em D  Em D
Nothing left, where a man once stood

[Pre-Chorus]
Am           D(C)
Through this doorway
       Em
What's on the other side
Am    D(C)
Never knowing
  Em
Exactly what I'll find
Am
Locked and loaded
                       D
Voices screaming, let's go
    G        D              Em
But I'm just doing what I'm told

[Chorus]
     C                        G
I'll take a life, ten others may live
D                          Em
Oh, that's just the way it goes
     C                        G
I'll shut my eyes, it hammers in my head
D                      Em
Where it'll end nobody knows
     C                       G
I'll take a life, ten others may live
D                          Em
Oh, that's just the way it goes
             C             G
It's playing over and over in my head
D                   G           D          *
Where it begins and where it'll end nobody knows

Yeah, though I walk through the valley of the shadow of death
I fear no evil for Thou art with me
Locked and loaded, gonna find my truth
Now I'm busting through, all hell breaks loose

Am          G          C         G(Em)
And you can all hide behind your desks now
Am          G              C           G(Em)  Am
And you can cry, "Teacher, come help me"
G           C       G(Em) Am
Through you all, my aim is true! My!

Am         G C G(Em)

Am         G C
Whoo-hoo!
G(Em)    Am    G C G(Em)
My aim is true!
