By 1986 the rebellion was considered to be generally under control and the military regime turned over power to a civilian president by the mediation of Costa Rica's President Oscar Arias as well as Honduran and Salvadoran governments. The improvement of the political climate also meant the resumption of overt US military assistance. Although the role of the FAG has been much diminished since the Guatemala Peace Treaty was signed in 1996, they have served the country after natural disasters, most notably after Hurricane Mitch and Hurricane Stan. During those disasters, helicopters were used to rescue stranded people, and cargo planes were used to carry food, water and emergency medical equipment to villages and remote places that had been cut off.
