This song is so easy.  In fact, it's going to be simple

No capo, no tuning, it's a loop of the following chords.

Em | D | G | G

The chorus however makes it a bit different.

Em    G       Em    G
I Can see and I can feel
    Em      G        Em      G
and you can see, and you can feel
   Em           G    Em           G
So why don't we just stand up and fight?
