Well, its not classified information, the 1,2,3,4,5 are
generally used by other armies in other countries as well, so here
goes.
1 = Personnel
2 = Intel
3 = Operations
4 = Logistics
5 = Plans
6 = Training
I'm not sure if i can say what the "S" and "G" prefixes are used
for, but once you get into the organization, you should be able to
tell. And all this is for the Army context, airforce and navy may
or may not organise themselves according to those numbers.
