The invitations for Prince Harry and Meghan Markle’s wedding have already been sent out, but now it turns out that special guests have just been asked to attend the biggest royal event of the year.

On Wednesday, March 28, the British Ministry of Defence announced that more than 250 members of the Armed Forces had been invited to perform “ceremonial duties” on the big day. “Members of the Household Calvary will form a staircase party at St. George’s Chapel, Windsor Castle as part of the wedding,” the statement explained. “The State Trumpeters and a Captain’s Escort from the Household Cavalry will also provide ceremonial support.”

Additionally, “streets within the precincts of Windsor Castle will be lined by members of the Windsor Castle Guard from 1st Battalion Irish Guards, and by Armed Forces personnel.”

Kensington Palace also confirmed the news by sharing a statement on behalf of the future bride and groom, tweeting, “Prince Harry and Ms. Markle are pleased that members of the Armed Forces will play such a special role in their wedding. The Military, and these units in particular, hold a great significance for Prince Harry and the couple are incredible grateful for their support.”

Prince Harry, 33, joined The Blues and Royals in 2006 and rose to the rank of captain while serving two tours in Afghanistan.

The military members will join approximately 600 guests who have already been invited to the special event on May 19, as well as 2,640 members of the public who will be watching the bride and groom’s arrival at Windsor Castle from the palace grounds. And that’s on top of the thousands of others who will line the streets to see Harry and Meghan’s carriage procession and the millions more watching at home.
