a. This article along with references (a) through (d), provide policy guidance, eligibility criteria, and civilian clothing allowance (CCA)rates for Navy Service Members required to wear civilian clothing in the actual performance of their official military duties.
b.Officers are precluded by law from receiving a CCA while assigned to a permanent duty station within the United States(including Hawaii and Alaska).
c. Enlisted personnel may be eligible to receive a CCA while permanently assigned to a duty station within, or outside, the United States; however, there are very few duties within the United States that would require enlisted Service Members towear civilian clothing in the actual performance of their official military duties, thereby justifying the payment of CCA.
