My job(4)

I had meaningful two experiences in the military working.
First, There is "the watch-keeping" in the military. I have the mission that I can't get sleep for 24 hours and manage a lot of things to don't be occurred trouble in the unit. It's like a dog who protect its home.
Originally I can get sleep after I finished "the watch-keeping"
but I couldn't go to sleep, because I had to work.
If I left work, someone who doesn't relate to my mission did my work.
