Once we found out my daughter was Colour guard Commander, we went down to the Cenotaph on Sunday with someone who had done it before and spent a good hour working out how she was going to do it and practising it.
Any ceremony like Remembrance Day requires some practice and working people through the evolutions. If you want to look good, you need to put some time in. Otherwise you increase the chance of failure significantly and with a much bigger than usual audience.
