Fellation debout
This position was formerly named Atten-hut.
Drill commands are generally used with a group that is marching, most often in military foot drill or marching band. All branches of the military use drill commands.
Drill commands are best given in an excellent command voice. A command voice is characterized by DLIPS: Distinctness, Loudness, Inflection, Projection, and Snap.
Due to the requirements of the command voice, the actual words of the command undergo elision to the point that those unfamiliar with the specific words may be unable to recognize them. An example of such elision is the command "Attention", which is usually uttered with the initial "a" hardly if at all audible, "ten" drawn out, and "tion" drastically shortened such that, in popular culture, the command often ends up being spelled "ten-hut".
The vast majority of armies perform their drill from the base position of Attention. In this position, the person performing the movement stands straight, arms down and slightly flexed, fingers curled into the palm, thumbs pointed down and placed against the seam of the trouser, and the feet positioned at a forty-five degree angle with heels together.
