The presidency of Alberto Fujimori (1990–2000) saw the Army regain protagonism in the public scene, but its increased political power led to some cases of corruption. The internal conflict ceased for the most part after the capture in 1992 of Abimael Guzmán, leader of the terrorist group Shining Path, but a brief border war with Ecuador broke out in 1995. During this period, women were incorporated into the Army first as conscripts in 1993 and then as officers in 1997. Army commandos had an important participation in operation "Chavín de Huantar" which put an end to the Japanese embassy hostage crisis. In 1999, one year after the signing of a peace treaty with Ecuador conscription was abolished and replaced by a voluntary military service for both genders.
