The Queen met soldiers and horses when she visited Combermere Barracks in Windsor.
She met several soldiers from the Household Cavalry Regiment and Cavalry Mounted Regiment. She saw soldiers cleaning and preparing items of uniform ahead of the state visit of the Emir of Kuwait to Windsor tomorrow.
She also petted the drum horse, which will be on official duty for the first time at tomorrow's visit.
The drum horse was renamed Adamas today, which means Diamond in Greek, in commemoration of the Queen's Diamond Jubilee.
Combermere Barracks is less than a mile from Windsor Castle and dates back to 1804.
