Soldiers Collapse During King's Birthday Parade Rehearsal in Scorching Heat.

Three British soldiers fainted from the heat during a parade rehearsal led by Prince William for King Charles' birthday parade. The event was a practice for the grand birthday parade of his father, King Charles, scheduled for Saturday, June 17. The Welsh Guards have been bestowed with the privilege of Trooping the Colour at this year’s parade, and their flag will be ceremoniously presented to the King. The event consisted of over 1,500 soldiers and 300 horses, representing the Household Division of Welsh, Scottish, Irish, Grenadier and Coldstream Guards.
