The award of acting rank is given to service personnel who are required to undertake the role and responsibilities of a higher rank, either for a limited period of time, where they have been selected for promotion but their promotion has yet to be confirmed by the individual service authorities, or they have not yet completed pre-requisite promotion courses.
In the event of death while holding acting rank, personnel will continue to be referred to by the rank with which they were formally addressed by immediately prior to their death.
