Things have moved on a bit from the focus just being on military secondary duties. Reprting officers (and hence promotion boards) should comment on extra-curricular activities. So, if you are active in the local community, running a scout group, doing voluntary work or the like, it can (and should) be commented on. Personally, I think there is more merit in helping a local community than running the Sqn tea bar. In general terms, military people are well looked after - many people in towns and villages are not so fortunate. Bottom line is that "community" activities should be commented on.
