I will preface my comments with the fact that I have never served in NDHQ. I certainly will at some point I am sure.
That being said, when I was a soldier operating solely in the lower tactical level, with lots of Infantry battalion time, I quite regularly had occasion to feel certain amounts of ill will toward my fellow officers serving in NDHQ. Likely unfounded as I was soon to discover.
I now quite regularly deal with the Land Staff as a Staff Officer in an Area Headquarters (for the last 2 months), and I have been continually impressed with the work ethic, responsibility, sheer volume of output, and the long hours put in by those I deal with on a regular basis. It is not unusual for me to call up the Land Staff at 1730 - 1800 hrs Eastern Standard Time, and talk to an overworked staff officer who is putting in the long hours required to keep the required information and direction flowing downward to their subordinate headquarters.
There might be places to trim in NDHQ, but the people I deal with on the Land Staff need augmentation, not cuts, to keep up with the volume and complexity of the issues they deal with.
I would, as others have, ask where those cuts should occur? No one that I deal with on a daily basis is superfluous to accomplishing the mission.
