It is so sad to see that the only two males of the Royal family who actually risked their life in wars to defend their own country (Andrew, because the Falklands are part of the UK) or fought for the freedom of Afghanistan (Harry) are the ones without uniform in this sad march. So you have to know from their medals they were active soldiers in real wars- And how stupidly they lost their ranks of honour to be stripped of the right to their uniforms now.
Plus I hope that at the moment the coffin is empty and the queen's body is either kept very cold or embalmed (but AFAIK to really platizcse a dead body you need to keep it chilled for some time) in a quiet room before the funeral. I understand that many people want to see the coffin and that there is a tradition to honour the late queen that way, but still I think there are better ways to deal with the actual dead body. Just IMHO, of course.
