Help me choose the correct uscg job (details inside)?

I am going to boot camp the first week of FEB and would like to have chosen an A school by the before i leave to fo to boot camp. I originally chose OS but i have been informed that it is a lot of sitting around and i like to stay active. The wait for a AST is too long so i dont know if i am willing to wait that long. i am planning on going in for 6 years active

My personality : i am a out going person. I like to have a active job where you have to use you body as well as your mind. I want to be "out there" in the field doing stuff, an not stuck behind a desk all day. Some action here and there would be nice. maybe even use the weapons training every once in awhile lol. thanks for the help
