Why is drill important?

drill is important because it helps to prepare troops for combat by rapidly carrying out oders

Soldier- The primary importance of drill is to prepare troops for combat by rapidly carrying out orders. During a ceremony, troops align in various formations and carry out commands with uniform precision. Army ceremonies instill honor, promote camaraderie and preserve tradition among Soldiers.

Engineering- Drilling engineering keeps tremendous and wide range of research for looking to the advanced tools and technologies to maximize the drilling rate or rate of penetration (ROP). Drilling rate has major impact to reduce the cost of the well or the total cost per foot of the well and accelerate the well delivery as well.

Dentist- When dentists drill into teeth, they are shaping an opening. This is to ensure all of the rot in the dentin is removed entirely. Another reason for drilling is to create a shape for the filling to bond and fill the cavity completely. Fillings can be either a silver/mercury amalgam or they can be plastic.

well when looking at this if you think about it   negativley and positivley   react with each other and when the first layer gets full they add layers it starts with 2 on the first layer and it constantly goes on until the official number is there
