AR 55-46 covers entitlement to transportation, overseas duty assignments, reservations, dependent student and Family member travel, escorts, evacuation, and emergency leave travel. It requires transportation, command sponsorship, travel authorization, documentation, and approval processes for covered travel.
In accordance with the JTR, commanders may authorize Family members to accompany or join their military sponsor overseas at government expense when the sponsor fulfills the requirements listed in paragraph 4 2. (paragraph 3-1)
Family members not entitled to transportation at government expense will not travel to the overseas location on a space-required or space-available basis. (paragraph 7-5)
When a Family member is authorized transportation per the JTR (for example, advance return of dependents), the sole-parent Soldier or one parent of a dual military couple, but not another person, may travel as an escort to the authorized destination of the Family member (who is not over 18 years of age, unless medically unable to travel alone) and return to the PDS (see the JTR). (paragraph 2)
If not available, the ITO will issue a statement of nonavailability of AMC transportation to the Soldier prior to arranging commercial transportation. (paragraph 2)
Cadets are not eligible for emergency leave transportation.
