Before the war, the island of Sahrani was divided into two countries. In 2006, the U.S. Army was in South Sahrani helping to train that country's military, having arrived there in 2002.
After the U.S. Army's training mission of the RACS was officially deemed complete in early June 2006, they began withdrawing from the country. The North Sahranians saw this as an opportunity for an easy conquest and invaded on June 10, 2006. The small remaining U.S. Army contingent, consisting of Humvees and a few Strykers, was ill-equipped and outnumbered by the SLA, which was armed with T-72s and BMPs. The SLA quickly captured the South Sahrani border town of Corazol and began advancing deeper into South Sahranian territory, with U.S. and RACS troops in retreat. As U.S. forces retreated, they destroyed several bridges in order to slow the SLA's advance.
On June 12, 2006, the SLA attempted to defeat the U.S. Army in South Sahrani with an amphibious assault near Paraíso International Airport. A U.S. Army Stryker brigade attempted to thwart the SLA assault and encountered heavy resistance. They were only victorious after the USMC provided close air support with AV-8B Harrier jets from an offshore navy LHD.
After capturing South Sahrani and driving the SLA out, RACS soldiers discovered a mass grave of civilians near the town of Cayo. The civilians had been killed by the SLA which was able to bypass nearby U.S. soldiers.
Originally the plan was to just drive the SLA out of South Sahrani but after the discovery of the SLA's war crimes, the decision was made to invade North Sahrani with the intention of overthrowing its regime.
However, it was later discovered that the Cayo massacre had been staged by the RACS in order to give South Sahrani a pretext to overthrow the northern regime. Cayo had been chosen due to what the South Sahrani government perceived as a lack of support from its people for its government. When U.S. forces neared a camp where Cayo's residents were being held awaiting execution, they were attacked by RACS soldiers, presumably to prevent the U.S. from discovering the camp. To quash U.S. and South Sahrani tensions, the incident was later dismissed by both sides as SLA commandos disguised as RACS soldiers.
On June 16, 2006, six days after the war began, U.S. Army Strykers and U.S. Marine M1A1s entered the North Sahranian capital of Bagango and captured it. The war was officially over with victory for the U.S. side.
It was originally believed that Torrez was the leader of North Sahrani and that he orchestrated the invasion. However, it was later discovered that President Richardicz, who was presumed dead, was still alive and was in charge. U.S. Army Special Forces teams searched the Sahranian islands of Rahmadi and Porto, discovered Richardicz and arrested him.
