Timing is everything: Royal Signals soldiers deliver for Trooping the Colour

When millions of people watched soldiers parade in perfect formation at last month's Trooping of the Colour, they witnessed a spectacle of military precision and national pride. What they didn't see was the invisible network of communications that made every step, salute and cannon shot happen at exactly the right moment.

Behind every perfect parade

Effective communication underpins everything — from everyday conversations to the grandest national occasions. But when the stakes are a live, televised state ceremony watched by millions, the margin for error is zero. Timing, coordination, and control must be flawless, and that responsibility falls to the Royal Corps of Signals’ 251 Signal Squadron.

Part of 10 Signal Regiment, based in Aldershot, 251 Signal Squadron provides secure communications for state ceremonial events and their work is far more complex than it might sound.

"Large ceremonial events such as Trooping the Colour require very careful coordination and involve many people who, though not in the public eye, are essential."

Lt Col Charlie Foinette, Brigade Major London District

A network across London

On the day of the parade, the Squadron positioned teams at key points across the capital, including the Elizabeth Tower, home to Big Ben, where they worked in close coordination with gun crews and the Guards Division to ensure that salutes were fired with pinpoint accuracy.

Woven into the fabric of the event itself were the Squadron's "street liners": soldiers embedded along the parade route, each equipped with communications linking them directly back to the operations room. Others were attached to key individuals, or assigned to specialist tasks, together forming a communications network that delivered real-time situational awareness across the entire event.

Lieutenant Colonel Charlie Foinette, Brigade Major for London District, explained just how much depended on this network: "Large ceremonial events such as Trooping the Colour require very careful coordination, and involve many people who, though not in the public eye, are essential.

"The troops on parade — and their horses — require transport, feeding, medical support, and most importantly the means to understand the progress of events or respond to an emergency. None of this would be possible without efficient communications, which is where 251 Signal Squadron come in."

"It was a privilege to be part of something that was watched nationwide. Our role was to make sure everything ran to time and, when it does, it's a great feeling knowing you've contributed to that."

Immaculate in every sense

It would be easy to assume the Squadron's work took place entirely behind closed doors — and some of it did. Personnel in the operations room and at mounting bases worked tirelessly out of sight. But many members of 251 Signal Squadron were on the parade itself, immaculate in ceremonial uniform, carrying radios to ensure that anyone who needed to stay in touch had a trained operator close at hand.

Lt Col Foinette added: "They were quite superb, and nothing we did in London in front of a national and often global audience could have happened without their support."

The pride of getting it right

For those involved, the reward was the moment everything came together perfectly. Corporal Adam Elghul put it simply: "It was a privilege to be part of something that was watched nationwide. Our role was to make sure everything ran to time, and when it did, it's a great feeling knowing you've contributed to that."

Major Beni Greenaway, Officer Commanding 251 Signal Squadron, echoed that sense of professional pride: "State events of this scale demand absolute precision, which the Squadron delivers through disciplined planning, resilient communications, and highly professional officers and soldiers who operate seamlessly on the parade and behind the scenes."
