Is their a Reg or manual that gives duty descriptionsof the various ES jobs? I dont mean the SQTR's. They give requirements to obtain the specialty. What I mean is actual job descriptions such as what does an Agency Liasion 1 do differently than an Agency Liasion 3 or whats the difference between a IC 1,2, and 3, or like what exactly does a PSC do or an OSC? Things like that.
60-3 covers this to an extent in the notes section. under where it says IC, AL, and GTM.
As for exact job descriptions I am sure someone has made something up but there is very little official information
