Dogs of War The Exploited

I've got a uniform
And I'm okay
Killing and ripping
Just for a day

(chorus:)
Dogs of war, but after you
Dogs of war, but after you
Dogs of war, but after you
Dogs of war, BUT AFTER YOU

Stab him with my pinner
I'll shoot him with my gun
I'm a psycho killer
Just for fun

(chorus)
Dogs of War
Dogs of War..
Dogs of War...
Dogs of War....

What does it mean?
And I don't give a damn
Let me forget
Cause tomorrow you're dead
