The Victoria Cross is awarded for "the most conspicuous bravery, a daring or pre-eminent act of valour or self-sacrifice or extreme devotion to duty, in the presence of the enemy" at any point after 1 January 1993. It may be presented posthumously, and, like its British counterpart, can not be revoked. The main distinction between the Victoria Cross and the Cross of Valour is the specific reference to "the enemy", which the Canadian government has defined as a force hostile towards the Canadian Crown, including armed mutineers, rebels, rioters, and pirates. This means that the Queen-in-Council does not officially have to declare war to give acknowledgement of the existence of a hostile force that fits the official description. Thus, a Canadian serving as part of a peacekeeping operation is eligible to be awarded the Victoria Cross if the service member fulfils the above criteria.
