I took these chords from the other tab, I just added lyrics and placement so its easier to read and play:

C
Joined the army for money for college
F
Now I?m trading bullets for knowledge
G
Isn?t quite what I bargained for
    C
They didn?t tell me there would be no war
Thought of the adventure, I thought it would be cool
       F
I could see the whole world and go back to school
       G
But for three months I?ve been on this ship
C
Staring at the water what a lame ass trip
When I get the call I got to jump in a copter
F
Fly into the desert, join into a slaughter
G
But you know I?m a pacifist
C
Shooting in the dark at a terrorist
   
Chorus 1  
           F     G      C
I got those pre-invasion jitters
        F         G       C
Ain?t no traitor, ain?t no quitter
F         G        C
Can?t get into the helicopter
    F              G           C
This ain?t like Playstation at all
