Coup d'état

A coup d'etat (pronounced ku det-ah), known also as an overthrow, putsch and coup for short, is an event where a party overthrows a nation's current government, usually via miilitary force, and replace it with individuals with beliefs identical to those of the coup group's.

Strangereal coups
In the Ace Combat universe, there have been two known coup d'etats.
 * 1992: An unknown terrorist faction attempts to overthrow the government of an unknown country, to which the country responds by employing the services of the Phoenix Squadron, sending them on special operations across the country in order to weaken the rebel forces. After a desperate last stand, the terrorist group is defeated, and the coup ended.
 * 2016: After the end of the Anean Continental War, the populace of the Federal Republic of Estovakia launches a national coup d'etat to overthrow "The Generals", a commitee of high ranking Estovakian officers who reformed the nation under a military regime following the civil war that plagued the country for several years, replacing them with an unknown government. This is the only known successful putsch in Strangereal, to date.
