Summary

The physical activities performed repeatedly according to the command of the group leader is called drill. This note briefly describes drills.

Things to Remember

  • The physical activities performed repeatedly according to the command of the group leader is called drill.
  • Right Dress helps to bring them back to straight rows and lines.
  • If the chief guest in staying at the right side or if anyone in receiving the salute then at that time the group should turn their heads right and execute the act of Eyes Right while the group in marching forward.
  • If the drill is the three rows or lines and needs the distance to be increased then Open Order command should be given.
  • Disperse command is given when the group is at attention position.

Drills

The physical activities performed repeatedly according to the command of the group leader is called drill. Drills make our body strong. We should practice the drills that we have learned before learning new drills. Here we will learn the following new actions.

Right Dress

In the process of performing drills, the rows and the lines shift forward and backward and move away from straight rows and files. Right Dress helps to bring them back to straight rows and lines. At the command of Right Dress, the right marker of the group should stand at attention at his place. Right marker means the person at the extreme right in the front row. In the Right Dress, the people on the front row close their right fists and stretch their right arms about an inch away from the shoulder of the right person. When the marker stays at attention, the row should be made straight according to the right marker's position. At this time, the people on the front row turn their heads right. In the same way, the row at the back should make the row straight according to the one in the front. For this, the right fist should be closed and the arm should be stretched nearly touching the shoulder of the person in the front. On this act, the body should not be bent and once all the positions are in order then hands should be brought down to attention.

Eyes Right, Eyes Front

If the chief guest in staying at the right side or if anyone in receiving the salute then at that time, the group should turn their heads right and execute the act of Eyes Right while the group in marching forward.The marching should continue with the heads turned to the right. If the group in carrying the flag then the flag also should be lowered down and continue the marching. Once the march past crosses the marked line in front of the chief guest then the marching should come back to simple marching. To do this Eyes Front command in given. On this command, the head should be turned in front and continue the marching. The right marker should keep on marching and look in front at the command of Eyes Right also.

Open Order, Close Order

If the drill is the three rows or lines and needs the distance to be increased then Open Order command should be given. Without Open Order the row or the line in the middle remains at their own places and the rows in the front and the back or the lines at the right and the left only move the given number of steps on the order of the command. After the command is ordered all should execute this act at once.

For example, the indication will be given as "The front row will open 3 steps in front and the back row will open 3 steps behind" and the command should follow "Open Order". To bring the row back to the previous position "Close Order" is given. At the command of Close Order the front row steps behind the same number of steps as many as they have stepped forward and the back row steps forward as many as they have stepped behind. After the Close Order, group comes back to their original position. These orders are commanded at attention position only.

Disperse, Dismiss

The group needs to be given a rest in the middle of the drill or if some other work came up and the drill needs to be stopped for some time then disperse is commanded. Disperse command is given when the group is at attention position. On the command of Disperse, the group turns right together and will disperse.

The Dismiss command comes into force once the drill is over for the day. This is also commanded by attention position. Dismiss is also similar to Disperse but in this, after stepping one step to the right with a salute, they should run off forward. Drills are not possible to learn in one practice. They should be practiced frequently.
