If I remember correctly my wartime placement would be 7th brigade, 2nd AA-battery, 1st platoon fire control & signalling chief.
Sounds a lot fancier than it actually is, and it involves a lot of sitting around, watching a big green hunk of metal and listening to guys who spot for planes with an old German periscope-type device from 1936.

I also have to use various sorts of communications equipment. This is what I did as a conscript too.
EDIT: Just thought I'd put in a picture of the German device.
