From The Man Who Would Be King (1975) based on a story by Rudyard Kipling. Daniel Dravot [Lecturing his Er-Heb recruits while Billy Fish translates:]

“Now listen to me, you benighted mockers! We’re going to teach you soldiering, The world’s noblest profession! When we’re done with you, you’ll be able to stand up and slaughter your foes like civilized men! But first, you will have to learn to march in step. And do the manual of arms without even having to think! Good soldiers don’t think, they just obey! Do you suppose that if a man thought twice, he’d give his life for Queen and Country? Not bloody likely! He wouldn’t go near the battlefield! One look at your foolish faces tells me that you’re going to be crack troops. Ohhh him there with the five-and-a-half hat size has the makings of a bloody hero!”

Slaughter your foes like civilized men … that seems instructive, even for a movie that’s from 1975 based on a book novella from 1888.
