I do not know the song "Soldiers of the Queen", but there *is* a Kipling song "The Young British Soldier" in which "So-oldier _of_ the Queen!" is the last line of the refrain; perhaps there is some confusion with that. "The Young British Soldier", however, does not monger war; it takes war for granted & gives sage advice on how to survive it where possible. It last stanza was much quoted on Usenet a couple of years ago, in no very jingoistic spirit:

When you're wounded and left on Afghanistan's plains,
And the women come out to cut up what remains,
Jest roll to your rifle and blow out your brains
An' go to your Gawd like a soldier.
Go, go, go like a soldier,...
