The grand parades will be part of the Royal Cremation Ceremonies for the late monarch, which are scheduled to take place between October 25 and 29. The training session on Tuesday involved representatives from various military units as well as the Armed Forces Academies Preparatory School. The session was necessary because all parties concerned wanted to organise the most elegant possible processions for the late, much-revered monarch. Parade participants are expected to dress well and exactly based on ancient traditions. There are 16 styles of attire for parade participants, who will number more than 1,700.
