Final answer:
There is no specific duration mentioned for temporary assignments to qualify for combat awards in the provided material, but it can be inferred that during combat or wartime scenarios, these may extend to six months or more, based on historical changes and current military practices.
Step-by-step explanation:
In the context of Naval Personnel temporarily assigned to other service commands, a specific duration for a temporary assignment to qualify for consideration for other Service combat awards is not explicitly stated in the provided reference material. However, considering standard military practices and the increasing obligations as shown in the reference where the Army's top general stated an intention to increase the annual drill requirement, it is likely that a commitment of several months may be required—commonly six months or more.
Furthermore, administrative policies pertaining to the eligibility for combat awards based on the temporary assignment duration would be established by the Department of Defense or the respective branches of the armed forces. Given historical contexts such as the mobilization of the National Guard during the Iraq War and the legislative changes initiated after World War II for women in service, it can be inferred that temporary assignments have evolved and can extend beyond the traditional 'one weekend a month, two weeks a year' notion, especially in combat or wartime scenarios.
Moreover, it is important to note that the President's ability to deploy troops for hostile reasons with a requirement for congressional confirmation within 48 hours and approval beyond 60 days may also influence the duration of these assignments.
