Operation Landslide (21 March 2038 - 20 June 2038) or commonly known as the Third Neocon Invasion of the Erebonian Empire was the third and final attempt by the Neocons to invade Erebonia. The plan called for the invasion of Erebonia through the supposedly weaker Calvardian lowlands and invading Erebonia from its eastern region. It called for 4 Army Groups, with 2 other groups invading from Eastern Liberl.

During Operation Downfall, the Neocon leaders discussed plans beyond the dates following the planned assassination of Field Marshal Kiriya Kitagawa, whom the Neocons have attributed the Heimdallr forces' victory in the past 2 invasions. General Chang Gwan-mook, along with other Neocon generals, including the Neocon 5 thoroughly discussed plans of invading Erebonia through another avenue by means of the Calvardian Lowlands. The Neocons believed that the Calvardian lowlands can be taken as a direct route that can ensure a dagger thrust towards the heart of Erebonia. The Calvardian capital city of Edith in the plan was to be besieged along the route until Heimdallr would fall into the Neocons, in which only then would Edith would also capitulate. The operation was to be carried out by the Spring of 2038, while the crossing into the Erebonian only after Kitagawa had been assassinated.

In 21 March, the Neocons launched a blitzkrieg attack that saw them reach the Erebonian border by the end of March, with most of the Calvardian lowlands falling under the Neocons, and Edith besieged. Although the Neocons had the upper hand, the Calvardian-Alterian forces would frequently harass Neocon columns heading for the Erebonian border, thus hampering their preparation for invading Erebonia. Following the "assassination" of Field Marshal Kiriya Kitagawa during Operation Downfall in 28 March, the Neocons crossed into the Erebonian border. The Heimdallr forces fought another defensive battle for the control of Erebonia's Eastern region. Although the Neocons had eyed to capture the Arseid Viscounty by mid-April, the Heimdallr forces fought to slow the Neocon advance. By late April, the Neocons had only reached the cities of Celdic and Bareahard, the capital of the Kreuzen Province. Then on 30 April came the shocking news that Marshal Kitagawa was still alive. Immediately, the Neocons attempted a major offensive to push further into Erebonia during the Battle of the Grand Granary, where the Erebonians managed to trap and pincer Army Group Fort. This gave Marshal Kitagawa the opportunity to send the Erebonian and Rubrumian Army Corps to force both Army Group Trieu and Army Group Chang into disarray and forcing them back into Eastern Liberl and Calvard by the first week of May. The Neocons would fight one final desperate attempt in the Battle of the Cuerdo Plains, which saw the remaining Neocon forces in Calvard retreat further East until in early June with Operation Daytime, which saw Heimdallr forces exhaust the Neocon forces into Calvard, forcing them to retreat back into Aurucolia. While Operation Moon was launched south of Calvard to liberate Eastern Liberl from Neocon control. By the end of June, Liberl and Calvard had been free of Neocon influence.

The Neocon Forces once again attempted to counter the Heimdallr Forces in a terrain that proved to be favourable to the latter. Despite every attempt of the Neocons during the operation, including the deployment of Seleucid artifacts, the Heimdallr forces remained in control of the battle until the Neocons had been forced back into Aurocolia and Bahatsva. Following the operation, the Neocons would never again be able to set foot into Scandinavia and in Europa.
