When more than one military unit with an organized service member group is deployed to the same location, one of the group leaders will be chosen to preside over the combined group. The stake, mission, or area president will make the selection, unless they authorize a Latter-day Saint chaplain to act in their behalf. If the group leaders are unable to contact the appropriate priesthood leader, the group leader holding the highest priesthood office and the highest military rank should assume responsibility for the combined group, and the other group leaders should serve as his assistants until contact with priesthood leaders can be made.
