Plural of commissary; officials or deputies sent with special authority, or shops on military bases that sell discounted goods.
From Latin commissarius 'one entrusted with a task.' Modern sense includes both government officials and retail shops on military/institutional bases.
Military commissaries are a massive benefit for service members—they offer tax-free shopping and prices 20-30% below retail, which saves military families thousands of dollars annually.
