Hmmm, nice poetry...

I observe a rise and fall in intonation and then a sudden rise again on the last line.

At first it was a steady rise in form of sharp events around and then it drops tactically into pity and unhappiness.

One would however imagine that the poem ends on a sad note until the last line where the narrator actually seems to know his calling.

This is my creed; I am a soldier, warrior by choice, In this life and the next.

And by far the best line
