Proper movement is key to looking good in JROTC.
Attention: The most basic of all the positions. You stand at attention by holding your hands closed and putting your arms straight down parallel to the seam on the side of your pants. You always look straight ahead with your shoulders raised slightly. You will not talk while at attention.
At Ease: You stand at ease when you are being addressed by someone, or you are otherwise in a looser setting. To correctly stand at ease, you lay your hands at the small of your back with your right hand over your left. You must keep your fingers pointed and your head straight; however, you are allowed to move your eyes.
Parade Rest: Parade Rest is very similar to standing At Ease, but the main difference is your hands are raised slightly above the small of your back and you are not allowed to move your head.
Facing Movements: Facing movements are how someone formally moves to face a direction in JROTC. Most all Facing Movements are tricky to learn by reading alone. I recommend first and foremost you attempt to get an upperclassman to help you learn, but if you want to try to understand, this guide is here.
*Keep in mind ALL drill commands MUST be given from attention. This means that you must learn how to stand at attention in order to properly execute the following commands.
Left/Right Face: The simplest commands of all military drill, left face and right face are fairly easy to understand. If you are given the command of Right Face, you pivot on your right heel, and you twist on the ball of your left foot. When you are done, you should be facing 90° right or left of where you previously were depending on the command. You should not raise your feet so that you become unbalanced. Generally speaking, it should not even be noticeable that your feet shifted at all. Practice this before moving on.
About Face: About Face is a little bit more tricky. About Face is a movement you execute to turn completely around. You have to place your right foot slightly behind your left and pivot on your left heel. When you twist with your right foot, you should turn clockwise, and you should be standing with your feet at 45° angle. This allows you to essentially already be at the position of attention when you turn around.
Half (direction) Face: Half movements are something that are usually not seen unless you are in the upper level of colorguard. The commands are usually something like the following: Half-Right Face. This indicates you should stop halfway through the movement to be halfway between where you normally would be and where you started. This is usually essential for non-symmetric rooms where you have to exit in a non-linear fashion. Half-About Face is not a command, please don't say that.
This is also necessary for Column movements (more on columns later)
Prepatory commands in marching are the same as general drill.
(i.e. Right/Left Face becomes Column Right/Left March.)
Columns: Columns are whenever the commanded unit is all facing the same direction, and they are all in formation right behind each other. The unit commander stands on the left side of the unit next to the middle of the commanded unit.
Flanks: Flanks are whenever the commanded unit is shoulder to shoulder facing the same direction. The unit commander stands in front of the unit and gives commands over his/her right shoulder.
Rear March: You must be marching in a column in order to properly execute a rear march. This command is given on the right foot. When you step out with your left foot after the command March is given you pivot all the around with both feet. You must be quick, however, because the unit doesn't stop moving.
Half-Column Movements: A half column movement is when you only pivot 45° instead of the usual 90° for column movements. This is an unusual movement that you will only see in special colorguards where looking good really matters.
Counter-Column March: This is a very special movement that allows a row to turn around and stay in the correct order. During the colorguards when we hand off the battalion commander to the next one, that is when we use this command. You must consult the cadet reference for further information.
