Background
A Staff Officer is a member of the House of Royal Intelligence (HRI) that has been assigned to a Kingdom's Navy or King's Army posting. While considered an Liaison Officer between the ultra top secret spy organization of the HRI and the Jod Military Forces (JMF), a Staff Officer is much more then that.
Staff Officers are typically seasoned veterans within HRI, Field Operators (FO) that have either reached that point in their careers where James Bond-like missions are too much on their knees and back or where they seek advancement opportunities within HRI as younger FOs. Either way, for old war dogs on their last legs wanting some peaceful last years before retirement or blood-thirsty FO's in their prime seeking career advancement, Staff Officers provide the HRI with a loyal corps of Liaison Officers between Espionage and Military.
Expected to act within the full interests of the HRI---and not the military---Staff Officers are usually disdained by those in the military who have to associate with them. Regardless of this, Staff Officers have earned respect---if with a lot of effort---by several Captain and Commodore-ranking officers in both the Navy & Army because of their extra intelligence assets and resources not usually allotted to military intelligence that have saved entire ships and units from destruction or capture. Furthermore, Staff Officers have been known----from time to time---to bend HRI policy for the betterment of the military, something that has earned the respect of the military and disdain of the HRI higher commanders.
Aside from being Liaison Officers, Staff Officers provide intelligence to JMF commands and units, have access to HRI and Royal Command assets as needed, and have the ability to re-deploy military units ("borrow" units) from other military commands to fit their current goals without prior permission if the circumstances call for such an action to be taken.
