Can someone be forced into becoming a Drill Instructor? If so, how do you avoid it?

Mikitary service is based on selfless service. Assignments are determined by need and qualifications along with potential. The avaerange NCO wants to be a drill sergeant. Only so many are selected a year, there are usually enough volunteers, when there are not they are selected by the branch. All NCOs need to take on a developmental assignment, this usually occurs twice ina career.

If you are in the military looking to get but not give you are in the wrong place, sacrifice is inevitable. You should take on any challenge and be determined to excel in any position. Excellence brings with it a feeling of accomplishment and pride. Sokdiers in a platoon at training respond to strong forthright keadership from men and women who exude confidence and competence. The reward is in seeing young people of the street develop into a foundational member of the nations largest team. They graduate and go to there units ready to face the unknown. They are a lie to do that because of the NCOs who shape them. I can’t name most of whom with which I served save those that you share a special bond with, I can still name my DIs. Man up and get ready, the military can be a great ride, but only for those who are in it for the right reasons.

SPC July Macias, every assignment has its good and bad. The thing is what you make it. Being a DS was one of the most rewarding things I’ve done. Seeing those new Soldiers I created graduate, knowing I had given them all the tools they would need to fight and win in Combat.
The days are long and the work is hard. But if we want good Soldiers to take our place when we leave, they need an excellent foundation. Creating that foundation is the Drill Sergeant’s job.

It's not called "forced." It's called DA Select. As for the Reserves and Guard, I do not believe there are any Guard Drill Sergeant units....but I could be wrong. There are Reserve Drill Sergeant units. Most folks will transfer in IOT promote. Others will get transferred in because of promotions. In those Reserve units, you will get spun up and trained up before you would even see Drill Sergeant Academy. If you don't mesh up, you'll probably get transferred out.
