What Happened to the Secretary of Defense?

If you were in the Army today, can I call you sir? Today. No. They're pushing against that. When you have the Secretary of Defense, Lloyd Austin, who was a retired four star general. And he had a brigade and an 82nd Airborne of it. Everyone looked up to him. But I don't know who this guy is now. He sent out the United States Marines. There was a study that was done. The University of Pennsylvania is saying that you should move away from calling people sir and ma'am because that's a firm in their gender. So just call them by their rank and their last name. Don'tcall them by their first name.
