This man is an anomaly. He used to be the director of the White House Office of Administration and Budget. He studied politics and law at the university, and later got an accountant's license by himself. To put it bluntly, this person is a bookkeeper and an expert in budget and cost control.
When I was the director of the CIA, I destroyed those CIA guys who spent money like water. What is sending him to the Pentagon now is a big axe to cut the budget, that is, to cut military spending and slim down. Why is he so keen on developing drones, or because it can greatly reduce costs?
