Kate paid a visit to the Salisbury Plain Training Area in Wiltshire this morning to meet with members of the 1st Battalion Irish Guards for the first time since becoming their Colonel.
Despite the wintry weather the princess wrapped up warm for the visit and got stuck in with battlefield casualty drills and could be seen assisting the soldiers.
She first met guardsmen who have been recently deployed on security force assistance tasks across east Africa in which they train and assist foreign forces. This includes training park rangers on counter-poaching operations.
Following this, she watched a medical training and casualty exercise that included a briefing on counter-explosive ordnance – the de-mining training which is currently being delivered by the Irish Guards to Ukrainian armed forces.
Kate was invited to take part in the training herself, during which she learned how to carry out battlefield casualty drills to deliver care to injured soldiers during a casualty simulation exercise.
The visit concluded with the princess viewing a demonstration of the weapon systems used by the Irish Guards.
It was revealed last December that Kate would be the new Colonel of the Irish Guards – a position previously held by her husband Prince William.
It came as William took over the position of Colonel of the Welsh Guard upon becoming the Prince of Wales, leaving Kate to take his place.
At Trooping the Colour, colonels usually wear full military uniform, with some even taking part in the parade on horseback.
Even though it has been announced that both Charles and William will ride on horseback during the display in June – Kate will not and instead travel to Horse Guards Parade in a carriage.
And according to the Daily Mail, Kate is also not expected to wear military uniform for the parade.
