The head of the British Army has said the Duke of Edinburgh "epitomised commitment and duty".
Prince Philip had close ties with the Armed Forces throughout his life, from serving during the Second World War to becoming the Royal Navy's Lord High Admiral on his 90th birthday.
In a virtual message, Gen Sir Mark said: "A Field Marshal for nearly 70 years, he [Prince Philip] held a range of colonelcies for our regiments and our corps, inspiring his units over successive generations and contributing advice and guidance during his lifetime of service.
"His Royal Highness epitomised commitment and duty. He was himself a Second World War veteran and an exemplar of that remarkable generation.
Watch: Chief of the General Staff, Sir Mark Carleton-Smith, pays tribute to Prince Philip.
"We will remember a dynamic, energetic and charismatic leader who gave his time and advice generously; a man who was fascinated by technology and the future, and we'll remember him for his deep interest in our soldiers and their families and for the example that he set of service and of duty.
"We deeply regret his passing, but we will remember him with respect, admiration and gratitude and, on behalf of the Army, I send my profound condolences to Her Majesty The Queen and all of the Royal Family," he finished.
Military chiefs from all three services, plus the Chief of the Defence Staff, have now paid formal tribute to Prince Philip following his death.
His funeral will take place on Saturday at Windsor Castle.
