President Pratt sent this explanation in a letter to Elder Bush:
As an Assistant you will help train and set the tone for missionary work throughout the mission. You will have a direct impact on every missionary serving in the Russia Vladivostok Mission. In this new calling you will continue to be an example of obedience, scripture study, work ethic, language ability, proselyting skills, and all other aspects of missionary work. Your burdens will be heavy at times, but your blessings will be great.
