Perhaps Tir, your preconceptions prevent you from seeing the humanity of a soldier.
You see a group of identicals acting in coordination, and forget that they are just individuals practiced in team work.
You forget that under the carapace of equipment, in each there beats a heart like yours, with the same dreams and fears, hopes and regrets.
And that is what Harvey was trying to say to you with his song.

Open your mind, and your heart, and read the song again.
Try to see that The Soldier is a man like you.
Keith.
