Military

The military of Eswatini (Umbutfo Eswatini Defence Force) is used primarily during domestic protests, with some border and customs duties. The military has never been involved in a foreign conflict. The king is the commander-in-chief of the defence force and the substantive Minister of the Ministry of Defence. There are approximately 3,000 personnel in the defence force, with the army being the largest component. There is a small air force, which is mainly used for transporting the king as well as cargo and personnel, surveying land with search and rescue functions, and mobilising in case of a national emergency.
