The Prince and Princess of Wales go to the parade every year to celebrate St. Patrick's Day.

For the first time, Kate gives the salute.

Kate often wears green, which is the national color of Ireland, to the event.

Kate's shoe heel got caught in a drain cover at the event in 2013.

Prince William gave Kate a hand so she wouldn't fall and lose her shoe.

Kate went to the Salisbury Plain Training Area recently and took part in military first aid training.

She helped soldiers and asked questions about how medics in the Army do first aid.

Kate put a tourniquet on a soldier's calf and said it was her first time doing it.

Kate was excited about the opportunity to learn by doing.
