An adjutant is like the teacher's assistant in a classroom. Just like how the teacher has a lot of things to do like teaching and grading papers, the person in charge of a group of soldiers or officers in the army has a lot of things to do. The adjutant helps them out by doing smaller tasks like organizing files, answering phone calls, setting up meetings, and making sure everything is in order. They make it easier for the person in charge to focus on the important things and keep everything running smoothly. Think of it like the teacher's assistant who helps the teacher to make sure the classroom is organized, everyone is getting their work done, and everything is running smoothly.
