Does any one know highest ranking US officer to be lost during the Iraqi operations I don't think it was higher than a full Bird colonel
Dtulsa there is a major difference in organization between the US Military and the forces and Organization of forces in Syria.
US Forces use a less centralized Command structure with General officers taking a more Bureaucratic role well Officers like Colonels and Lt. Colonels and Majors operate as Field commanders. A major factor in this is the US NCO corps who take roles more often ascribed to officers in many other Armies. Add in Communications and It means that O6 Paygrade and above rarely are needed in the field.
For the record the highest ranking officer lost in operations was Lt. Gen Greene in Afghanistan other then him it's a Rarity to find a US casualty ranked higher than Lieutenant Colonel
