British soldiers will march in Red Square in Moscow for the first time on Sunday to mark the 65th anniversary of the defeat of Nazi Germany.
Seventy six soldiers from 2 Company 1st Battalion Welsh Guards will march beside more than 10,500 Russian troops and others from the US and France.
The multi-million pound parade will include a 1,000-strong military band, tanks, missiles and 127 aircraft.
The forces are taking part at the request of the Russian government.
The British detachment will also include members of the Royal Air Force band.
The commanding officer of the Aldershot-based 1st Battalion Welsh Guards, Lt Col Rupert Thorneloe, was killed during their tour of Afghanistan six months ago.
He is the most senior British army officer to die in action since the Falklands conflict. Lt Col Thorneloe died alongside Trooper Joshua Hammond when a roadside bomb hit their vehicle.
"It was an emotional tour," said Guardsman Thomas James.
"This is the first time I’ve been on official parade in my tunic since we’ve been back. It’s an honour to be here."
Guardsman Ian Mundy said: "There is a sense of pride to be in this massive parade on Red Square.
"It seems that everyone is interested in us as well and I’m proud to be a part of that."
The Welsh Guards are staying at the Moscow Military Academy as guests of the Russian Army.
Ahead of the event, they have been given a guided tour of the Kremlin, invited to concerts and taken part in a cultural tour of the city via a boat trip up the Moscow River.
