King Charles III's eldest son has showed off his military skills in extreme conditions near Russian border, sending a message of courage from a tank.
The Prince of Wales appeared in high spirits as he took his seat in a Challenger 2 tank at Tapa Camp near Russian border.
The future King, who is in Estonia to support UK troops, braved freezing cold in mud-churned military training area.
Kensington Palace has shared videos of Williams with his statement. In the pictures and clips is seen in camouflage uniform, peering from a Challenger 2 tank and then an armoured fighting vehicle.
During his two-day trip to Estonia, Prince William visited some of the 900 British troops in this multinational force, including soldiers of the Mercian regiment of which the prince is colonel-in-chief.
He was given a tour of the military training grounds at Tapa Camp - part of Operation Cabrit which is the UK's contribution to secure Nato's "collective security and defence" in this vulnerable Baltic region.
The prince, who was wearing a Nato badge on his uniform, was shown field training for this battlegroup, meeting Estonian and French troops too.
He asked soldiers about their deployment in terms of the "context of being so near to Russia" and wondered whether this felt more real than previous training.
