There is a huge difference between the Serviceman "Warrior" and the Serviceman (or woman), "technician". Something most people outside the services have no concept of. Teachers are some of the worst at recognising this.
However, that being said, my mother was a radar tech in the RAF before she married. She then retrained into teaching and had a full career in teaching. From her peers I'm told she was an excellent Primary teacher.
Teachers are an interesting breed. They are the last person in the world I will willingly teach anything about computers or software. I include my mother in that which just goes to show that teaching is a process which creates the end result.
The most common phrase I hear from a Teacher when trying to teach them about using a computer is
"I don't want to know that I want you to tell me what I want to know"
I say the same thing every single time to every teacher who ever says that to me.
"And what would you say to a child who told you the same thing".
I had a running battle with Mrs S about this for nearly a decade until we had a furious row one weekend about "This computer has lost my files again and you will find them in ten seconds and I've waited all week to get them and I really needed them". I finally lost my cool and, rather heatedly, told her that the computer had not done anything of the sort, that she had lost her files because she had decided that she could use a computer without understanding how to use the file manager (Windows Explorer). After that she finally submitted to learning something I had been trying to teach her for 10 years and, funnily enough, the computer never lost another file of hers.... Strange things computers....
I have 6 teachers in the family and at least another 6 close friends are also teachers. Bored, want to be a teacher? I can think of easier ways to drive myself insane but not many more sure....
