Drill instructors need to be careful about their own limitations. Many do not realize how exhausting the job can get. Many haven’t been prepared, or they are told but do not realize the extent that exhaustion spans. Many new drill instructors are shocked to learn how tired the job makes them. It is very physically and mentally demanding. Not only do they have to keep up with recruits but they have to lead them and not look tired doing it. Many drill instructors unintentionally lose weight while on this tour of duty. The constant running around and activity day and night can burn a lot of calories. They have to be on call at all times when on duty so they may not have a chance to eat regular meals.
Drill instructors have left their own MOS, something they have been doing since their enlistment, and transfer to a new billet where they have to learn a lot of things in a relatively short period of time. This takes them out of their comfort zone and puts a certain amount of pressure on them to perform quickly. The entire experience is a learning process. They take what they have learned and apply it to the recruits.
Drill instructors are tuned in to watch for their fellow drill instructors. If there is any sign of distress such as passing out or injury, they are quick to help them with minimal interruption to training. In the middle of being screamed at and running around one time, I noticed that one of our drill instructors was being carried by two other drill instructors in what seemed to be a situation where the drill instructor was close to passing out. The quick speed in which they reacted and the quiet way they did it made it hard for me to believe what I saw. The drill instructor who looked faint was still trying to bark orders as she was taken to the drill instructor hut. I’m telling you, these men and women are fearless to the end and will do their job until they can no longer do it or are relieved of their duty.
Everything is a learning process. Being a drill instructor is no different. New drill instructors are mixed in with experienced drill instructors so that they can learn from each other. All of them are constantly changing and adapting to the situation and scenarios around them. Recruits can throw out weird situations at times, so each recruit training cycle is a learning experience for all drill instructors.
If you make it to boot camp and find that the constant screaming in your face is screwing up your sunny disposition, remember that despite the drooling growl of their faces, drill instructors are human and they are constantly learning on the job. Either way, PUSH!
