groups other than DMG,PSP,FSP
 

on this forum, much is present about service growth of DMG and PSP & normally ppl know about them.
a detailed account of FSP is given by respected Shahid sahib
however, what about other services---- their plus and minuses.
i ll like to see the service description of services other than dmg, psp & fsp.
a friend was telling me that in [B]postal service[/B], grade 17 officer is the appointing authority of grade 7 man, which is not the case in any other service. moreover, in postal service, officers enjoy postings/ attachments in switzerland which is the headquarter of international post.
these things were unknown to me, and i do believe, these will also b unknown 2 u ppl.
so, if someone has knowledge about these services, do post here, 2 share knowledge with others.
