Don't think my opening post came across in the right way.
When i mentioned pen pusher i was referring to the fact that most of what i have been told by ex navy/marines about officer trades/specialisations is that they spend most of the time doing admin work.
When i mentioned that i didn't want to be just a marine, i meant that i wanted to focus on a specialist trade then do the aacc so that i could do the specialist trade and have the combat element.
I can't find much online about what trades typically do the aacc other than medics
Until this thread is moved to somewhere more suitable, I shall refrain from saying what I should say to this sock puppet.
I could help, however as I was only ever "Just a marine" (I think you'll find we have Royal Marines, and have done for some time.) I doubt I'd be able to provide you with the info your after. You Graduate of playing services.
