Alongside the pictures posted on social media, Kate shared a touching tribute: “Today on Armed Forces Day, William and I would like to pay tribute to the brave men and women, past and present, serving in all of our armed forces, at sea, on land and in the air, here in the UK and around the world,” she wrote.

She continued, “Thank you for all you and your families sacrifice to keep us safe.”

“Last year, I was honored to spend time with the @BritishArmy to see how they train serving personnel and new recruits. It was wonderful to see first-hand the many important and varied roles the military play day in, day out to protect us all,” Kate wrote.

Before signing off with a simple “C” for Catherine, Kate promised to continue visiting the armed forces with visits to the Navy and Air Force: “I look forward to discovering more about the @RoyalNavy and @RoyalAirForceUK in due course.”
