On NATO's anniversary, 23 of the alliance's 29 nations whose militaries co-exist in Gloucester were determined to celebrate despite the weather.
"I'm glad that my country decided to fully join NATO again a few years ago," said Lieutenant Colonel Ben Rossillon from the French Army.
"We kept the values that were drafted 70 years ago in Washington," said Major General Maurizio Boni from the Italian Army.
"The alliance is an enduring alliance [with] enduring values."
Watch: celebrations took place in Imjin Barracks, Gloucestershire, home of the Allied Rapid Reaction Corps.
It is not clear what challenges face the alliance over the next 70 years, but the ARRC’s new enhanced role in NATO places the UK at the forefront of the alliance’s plans for how it will respond to whatever lies ahead.
