Prince William, the Prince of Wales, has told Commonwealth troops the Queen will be "looking down" on her funeral service.
William and his wife Kate, the Princess of Wales, visited Army Training Centre Pirbright in Surrey on Friday afternoon where they spoke with military personnel from Australia, Canada and New Zealand participating in the procession on Monday.
Speaking to Commonwealth troops, who have been rehearsing this week, the pair also told of how "strange" it has been going from the Queen's Platinum Jubilee to her funeral in a matter of months.
William, talking with troops from Australia, was heard saying the difference between the celebrations in June and the funeral preparations shows "the highs and lows of it all".
Meanwhile, Kate, who was speaking with Canadian military personnel, said: "Going from that (the Jubilee) to this in a few months is very strange."
She was also heard discussing "lack of sleep" with the troops.
William was heard speaking with troops from the New Zealand Defence Force about how the Queen would be keeping an eye on Monday's proceedings.
Greg Gifford, 31, told the PA News agency: "One of the key things I took away from what he said was how the Queen will definitely be looking down on the whole funeral service.
"He said she would be interested in the detail of the soldiers, how the drill is carried out, its precision, our dress, things like that."
The couple also watched a traditional haka performed by 25 troops from the New Zealand Defence Force.
There were 64 members of the Canadian Armed Forces and 28 members of the Australian Defence Force at the centre.
The troops are in the UK because they are involved in the procession during Monday's service, alongside British soldiers.
They are being accommodated at Pirbright until the funeral and are rehearsing their roles in the ceremony, with practice marches occurring across the site.
