Well apparently President BoneSpurs and his Hand Picked Secretary of War (A more perfect example of the Peter Principle would be harder to find) felt the need to lecture members of the military about the proper use of grooming and physical training to members of the military who have decades more experience than either of them.

A Novice Defense Secretary Lectures the Brass on What It Takes to Win
Senior officers, summoned from around the world, are entrusted to manage complex military operations. They got a lecture on fitness and grooming standards.
Mr. Hegseth’s vision of the military and what it should be was almost entirely defined by his 12 months of service in Iraq and his experience as a major in the Army National Guard.
Much of his address focused on the kinds of issues he would have dealt with as a young platoon leader in the 101st Airborne Division in Iraq or as a company commander in the Guard. He talked about grooming standards. “No more beards, long hair, superficial, individual expression,” he told the brass. “We’re going to cut our hair, shave, shave our beards and adhere to standards.”
He preached the importance of physical fitness. “Frankly, it’s tiring to look out at combat formations, or really any formation, and see fat troops,” he said. “Likewise, it’s completely unacceptable to see fat generals and admirals in the halls of the Pentagon.”
And he suggested that fixing these problems was the first step toward repairing a military that, since World War II, had lost the ability to win wars.
To some, Mr. Hegseth’s speech was poorly matched to his audience of senior officers who in most cases are responsible for complex military operations such as the maintenance of nuclear submarines, America’s global alliances or the development of complex air-tasking orders, such as the one needed for the strikes on Iran’s nuclear program earlier this year.
The military officers assembled in the room listened silently. It is likely, though, that at least some of them were seething at his suggestion that their collective failure to enforce basic standards had caused, or even contributed to, the military’s failings in Afghanistan and Iraq.
