The first reason is that female tutors are not good enough for some students. As we all know, female teachers are not a deterrent to many naughty students, and so are female instructors. Therefore, in order to better manage students, they are generally male instructors. Moreover, female instructors are weak, and they will be on the weak side when they conflict with some students, which makes military training have no original taste.
The second reason is that most female instructors are not as physical as male instructors. As we all know, most girls are not as physically strong as boys, and so are instructors. However, military training is extremely tiring, so female instructors are generally not selected. Male instructors have good physical strength, so most schools choose male instructors as the main ones.
And male instructors will suffer more, and there are many ways to manage them.
The last reason is that male instructors are more likely to integrate into students. Because naughty students are basically boys, it is difficult to manage if the instructors are girls, it is easy to make friends with them if they are male instructors, and it is easier to manage during military training.
And girls don't have this affinity. Therefore, in military training, only male instructors are often seen in military training, and there is almost no military training for female instructors. Male instructors are often more likely to take military students than female instructors. Girls are softer than boys, so they choose more boys. Moreover, there are few options for girls' military training, and many girls will not find jobs such as taking students for military training. And many students tend to be male tutors. Therefore, female instructors suffer a little.
