Tax-free Boarding
The military usually offers room and board (including meals) as part of the pay scale for each service person. While they’re on active duty, they receive an allowance or get free meals. New recruits tend to live on the base, though.
Healthcare and Dental Care
Active-duty personnel and their families get access to hospitals, clinics, and dental services on/near military installments. In fact, active-duty personnel gets free life insurance, which protects their families if they’re killed in action (KIA).
