PEOPLE have reported that the Markle's, in particular Meghan's father Thomas Markle, will receive a family coat of arms, which is traditionally given to the father of the bride before a royal wedding.
More than 250 members of the Armed Forces are expected to perform ceremonial duties at the couple's wedding on May 19.
"I am proud that members of the Armed Forces have been asked to take part in the ceremonial celebrations taking place on the royal couple's wedding day", Air Chief Marshal Sir Stuart Peach, Chief of the Defence Staff, said in a statement released by the United Kingdom government.
Even before the wedding, residents and visitors will see an increased police presence from police officers - both armed and unarmed - and search dogs, the mounted section, the roads policing unit and the National Police Air Service.More news: Two Koreas in high-level talks ahead of summit

British Transport Police will patrol train stations and carriages, while arrivals to Windsor train stations will be screened and searched.
