Which ceremony occurs when there is a time lapse between commanders?

The Assumption of Command ceremony is specifically designed to formally transfer authority from one commander to the next. This ceremony emphasizes the continuity of leadership and the responsibilities that come with command. It is particularly significant during a time lapse between commanders, as it serves to re-establish authority in the unit and reassure personnel about their leadership structure.

In contrast, a re-enlistment ceremony celebrates a service member's decision to extend their commitment to the military but does not involve the transfer of command. An award ceremony recognizes individual achievements or contributions but similarly does not address changes in command. A retirement ceremony marks the conclusion of a service member's career and, while it may involve a change in command, it is focused more on honoring the retiree than formally transitioning command authority. Therefore, the Assumption of Command is the appropriate and relevant ceremony for situations where there are changes in command amidst a time lapse.
