Military aid

Military aid is aid which is used to assist a country or its people in its defense efforts, or to assist a poor country in maintaining control over its own territory. Many countries receive military aid to help with counter-insurgency efforts. Military aid can also be given to a rebellion to help fight another country.

This aid may be given in the form of money for foreign militaries to buy weapons and equipment from the donor country.

Military aid is often the subject of controversy.
