As a Colonel in the Irish Guards, Kate Middleton went to the St. Patrick's Day parade in Aldershot.

Body language expert Judi James analyzes her interaction with Prince William during the ceremony.

James notes Kate's military body language and William's response.

Another expert, Darren Stanton, says Kate wanted to assert her authority by wearing a "superhero color."

William inherited the title of Colonel of the Welsh Guards from his father.

The couple previously attended the parade together in 2019.

The event had no large crowds due to the  pandemic.

Kate handed out shamrocks to officers and warrant officers, a tradition dating back to 1901.

Kate's first time attending the parade as Colonel marked an important milestone.
