The Independent State Allied Forces,[1][2] (alternatively Independent States Allied Forces)[3][4] abbreviated as ISAF (アイサフ ISAF),[5] was a military coalition composed of nations from Usea against the former Federal Republic of Erusea during the Continental War.[6]



The ISAF was created from the Central Usea Treaty Organization (UTO), a multinational government organization consisting of Usean nations, which included the Federation of Central Usea (FCU) as well as Erusea. After Erusea's takeover of San Salvacion and Stonehenge in early August 2003, tensions escalated between Erusea and the UTO. The threat of an armed response eventually forced FCU President Robert Sinclair to announce the UTO's dissolution and the creation of a military coalition, the ISAF, in September that year.[7]

Following Erusea's use of Stonehenge as an anti-aircraft weapon, the resulting loss of aerial power forced the ISAF to retreat to its GHQ at Istas Fortress in south-central Usea. Outmatched by the STN's overwhelming firepower, the ISAF retreated from the mainland to North Point, which became the site of its new GHQ soon after.[6]

Despite Erusea's attempts to eradicate the ISAF, North Point became the base of operations for ISAF's efforts to rally its troops trapped on the mainland. By September 2004, ISAF relied on its air forces to perform airstrike operations and impede the Erusians' military efforts. The ISAF began scoring crucial victories in the east, such as the destruction of a major oil refinery (Operation Early Bird)[8] and the sinking of Erusea's Aegir Fleet (Operation Rough Seas).[9]

Following the successful launch of a reconnaissance satellite from the Riass Space Center in the Comona Islands,[10] the ISAF launched a massive counteroffensive on the mainland, beginning with the amphibious landings of Operation Bunker Shot in January 2005. The offensive culminated in the destruction of Stonehenge due to the heroic actions of ISAF ace Mobius 1.[11]

The fall of the STN facility led to a second ISAF campaign towards Erusea territory: the ISAF liberated San Salvacion in July 2005 (Operation Firefly)[12] and, by September, had captured the Erusian capital, Farbanti (Operation Autumn Thunder).[13] Despite the Erusians' unconditional surrender, the ISAF would deploy a special forces unit and the newly formed Mobius Squadron one week after the war's official end to stop the use of Megalith as a retaliatory weapon. The ISAF was victorious once again, and widespread disaster was averted as a result of Mobius 1's actions.[14]

Post-war period

The ISAF continued to exist after the conclusion of the Continental War and oversaw the formation of a post-war Erusian government. In September 2006, a resistance movement known as Free Erusea mounted an armed insurrection against ISAF and the interim government. In response, the ISAF launched Operation Katina to suppress the uprising. As a result of Katina's success, the ISAF obtained experimental autonomous flight systems from Erusian X-02 Wyverns that had been seized by the Free Erusea forces.[15]


ISAF Insignias

As a military coalition, the Independent State Allied Forces was initially comprised of eleven core Usean nations, which later expanded to a total of sixteen members. The ISAF member states were unofficially led by the FCU. The main symbol of the ISAF was an arrangement of triangles known as the "Three Arrowheads".[16]

The purpose of the organization was to restore and maintain stability within the Usean continent. Each member state was guaranteed the right to collective self-defense: any military action taken against an ISAF state would be treated as an attack on the organization as a whole.[7]

The military arm of the ISAF was composed of the individual armed forces of its member nations, including ground, air and naval forces.
