The US Secretary of Defense recently signed a memo, moving to a conditions-based approach to personnel travel. The Secretary's #1 priority during the COVID-19 pandemic is protecting the military workforce.
As of June 29, 2020, there are 47 US states that meet the new conditions to lift travel restrictions, subject to individual military installation assessments.
California, Florida, and Michigan are the only US states to which service members are not authorized to travel for permanent-change-of-station moves, temporary duty, and other non-essential purposes.
However, if installation conditions are subsequently not met, the approval authority decides if travel restrictions should be reinstated, stated this DoD press statement.
