I'm no good at this, but here i go.

Soldier
Soldier you must be brave
you signed for this and so you are
Yesterday a boy,playful and cheery
Today a man solemn and rough

Soldier, your allies have gone
Yet you stay, why?
The ememy remains, you feel their eyes
You walk off with a defeated expression

The enemy swarms in attack
You turn around ready to fight
Allies run in after hearing the guns
You fall to the ground, your world goes black

You died that day,a warrior
We won the battle, but lost you
You will be remembered
Always living on in our hearts, minds and souls

Soldier,bravery is defined as you
