While I was in the Navy from 1985-1989 we made rank by passing tests and
time in service not by doing community service for example bake sales.  I
never heard of such a thing. It was strictly on your ability to know your
job.   The Armed Services are now  understaffed and underpaid.  It is not
easy being away from friends and family do what these people do.   If it was
not for them volunteering to go in to the Armed Services we would not be
able to have a discussion like this on the internet.
