It had lyrics like:

"Military governmental contract"

"Private bill is nearly blind without his contacts, and that's just fine with me"

"Send him off to a foreign land, put a great big weapon in his hands"

"Give 'em all Nintendos, and load 'em up with Doom"

I'm paraphrasing, of course, but stuff like that... but no variation on any of those phrases seem to lead me to the song.

Pic semi-related, as it was sung at a Remembrance Day ceremony at school a few years ago.
