Operation Viper was the code name given by the Kolodorian People's Defense Forces to the invasion of Tír Tairngire, which led to the outbreak of the Vinyan War. The invasion was planned out between 1973-1974 and finalized on 16 November 1974. Viper was detailed by the Operations Directorate of the KPDF Central Command and primarily devised by Lt. General Noldis Brunkevičs, who would go on to lead the invasion. To carry out the invasion, the Second Army Group was organized, composed of four corps for a total of 200,000 men under arms, over 3,000 armored vehicles, 2,000 artillery pieces, and 150 aircraft. The entirety of the Tairngiric Armed Forces by comparsion amounted to just 110,000 men and was wholly outgunned. Originally, Viper was a limited offensive aimed at seizing control of Zavijava, land owned by Tír Tairngire but inhabited primarily by ethnic Kolodorians. The invasion was carried out on 11 April 1975 and was met with early success but after reaching the Glanhír River, the planned extent of advance, the Second Army Group was ordered to continue on and capture more of Tír Tairngire despite protests from Brunkevičs.

The subsqeuent drive south was halted by combined Anglian and Ivernic reinforcements, whom halted the KPDF and later repulsed Kolodorian forces from Tír Tairngire. The war would go on to last five years and result in hundreds of thousands dead on both sides.
