Security Force Assistance (SFA) is the strategic-level military practice of a donor country creating, equipping, training, advising, and supporting one or more groups of a foreign host country, such as a military, police, paramilitary, coast guard, intelligence organization, border police, etc, which contribute to the national security of the host country. SFA is used when improving the security of the host country aligns with the national interests of the donor country. It may be used alongside or instead of larger commitments of the donor country's military personnel and matériel. This means SFA can provide an alternative to large-scale operations if a war becomes controversial or politically difficult.
