Poem:
  Danny Deever
by Rudyard Kipling (excerpt)
  "What are the bugles blowin' for?" said Files-on-Parade.
"To turn you out, to turn you out", the Colour-Sergeant said.
"What makes you look so white, so white?" said Files-on-Parade.
 "I'm dreadin' what I've got to watch", the Colour-Sergeant said.
For they're hangin' Danny Deever, you can hear the Dead March play,
The regiment's in 'ollow square—they're hangin' him to-day;
They've taken of his buttons off an' cut his stripes away,
An' they're hangin' Danny Deever in the mornin'.
  "What makes the rear-rank breathe so 'ard?" said Files-on-Parade.
 "It's bitter cold, it's bitter cold", the Colour-Sergeant said.
"What makes that front-rank man fall down?" said Files-on-Parade.
"A touch o' sun, a touch o' sun", the Colour-Sergeant said.
They are hangin' Danny Deever, they are marchin' of 'im round,
They 'ave 'alted Danny Deever by 'is coffin on the ground;
An' 'e'll swing in 'arf a minute for a sneakin' shootin' hound—
O they're hangin' Danny Deever in the mornin'!

If you are, then the answer would be letter A.  the movement of soldiers on foot.
