Some of the troops involved now are from across the Commonwealth and the British Overseas Territories.
That's in addition to the Sovereign’s Bodyguard and Royal Watermen.
This is an absolutely huge procession with 4,000 armed forces personnel involved.
The graphic below shows some of those providing a royal escort.
Alongside the coach walk nine grooms, six footmen and four Yeomen of the Guard as well as members of the Royal Watermen.

Viewers in the UK can also tune into BBC One or BBC Two - or to a radio simulcast across BBC Radios 3, 4 and 5 Live, and BBC Sounds.
If you’re outside the UK - watch on the BBC News channel, or listen on the BBC World Service.
This time, King Charles and Queen Camilla are being driven in the Gold State Coach.
Only the monarch and their spouse are allowed to travel in this carriage, which is over 260 years old and has been used at every coronation since that of William IV in 1831.
It’s heavy - four tonnes to be exact - and requires eight horses to pull it.
The command is now given for this huge procession to step off.
Nearly 4,000 UK armed forces personnel are in formation - marching in step with each other.
This is a major military ceremonial operation that’s been described as the largest of its kind for a generation.
There have been six weeks of rehearsals to make sure all the marching bands are synchronised.
The newly-crowned king and queen are leaving Westminster Abbey and will shortly take part in a second parade - much larger than the first - and with other royals involved.
The Coronation Procession is heading back to Buckingham Palace via the same 1.4-mile (2.3km) route that was used this morning.
Early on, we’ll see the Royal British Legion provide a guard of honour in Parliament Square.
We’ll bring you more on how the King and Queen themselves will be travelling in a moment.
The bells of Westminster Abbey are rung as King Charles III leaves the building.
The Coronation Procession will be under way shortly.

We're about to see the Coronation Procession take King Charles and Queen Camilla back to Buckingham Palace.
It's already been a day of lavish royal pomp and ceremony.
"God save our gracious King," sings the congregation as Charles makes a reappearance - and begins his walk out of Westminster Abbey.
He's now wearing a different crown:

Reporting from Westminster Abbey
The Gold State Coach has just pulled up outside Westminster Abbey, as the ceremony draws to a close.
It’s so ornate, straight out of a fairytale. The gold shines bright against the rainy backdrop.
It is in fact covered in gold leaf. The first king to use the coach in a coronation was William IV in 1831 and it has been used at every coronation since.
The emphasis has switched to the music now that the King and the queen have retired to St Edward's Chapel.
The latest piece we're hearing is Te Deum Laudamus, sung by the choir. Its title translates as "God, we praise you".
The King and queen now descend from their thrones and enter St Edward's Chapel behind the high altar.
They're getting ready for the Coronation Procession, which will take them back to Buckingham Palace.
Another striking snap for you. After King Charles was crowned, his son Prince William kissed him on the cheek.
Back in the abbey, the Archbishop of Canterbury has just led another prayer and a blessing.
The congregation sings a hymn. While that happens, let's bring you some images of Camilla, the Queen Consort, being crowned with Queen Mary's Crown.

There are a few hundred anti-monarchy protesters at Trafalgar Square. The Coronation service is being relayed to the crowds by loudspeakers.
Every time the words King Charles are mentioned, the demonstrators chant: “Not my king”.
In other parts of the service they are booing, shouting: “He’s just a normal man.”
After the anointing when the words “God save the King” were pronounced, the anti-monarchists booed loudest of all, and started chanting “not my king” again.
The choir now sings Agnus Dei - an ethereal piece composed by Tarik O'Regan especially for today - and the King and queen take communion.
Archbishop of Canterbury Justin Welby continues with his address.
He then introduces the Lord's Prayer, asking the congregation to join him.
King Charles III and Queen Camilla are no longer wearing their crowns.
The final part of the service will see the King and queen taking Holy Communion - the principal act of worship of the Christian church.
The choir is now singing Sanctus, composed by Roxanna Panufnik for this service.
You can see St Edward's Crown here in intricate detail, after it was placed on the King's head.
Made of solid 22-carat gold, the 360-year-old crown is over 30cm (1ft) tall and it’s heavy, weighing about 2.23kg (nearly 5lbs).
As the music continues, let's bring you up to speed with how the crowning moment was greeted outside Westminster Abbey.
A gun salute was fired by The King's Troop Royal Horse Artillery, stationed at Horse Guards Parade, and also a bit further down the River Thames at the Tower of London.
In total, gun salutes sounded at 13 locations around the UK, including in Edinburgh, Cardiff and Belfast as well as on naval vessels.
The traditional salvo involves 21 rounds, fired at 10-second intervals.
