The Ukrainian-Holidian Conflict

The Ukrainian-Holidian Conflict was a small war between the Holidian Empire and Ukraine. The entire conflict lasted from September 9th, 2028 to January 25th, 2037. The war would hold the distinction as the last war where propeller-driven fighter aircraft in active service (though, the last war to have propeller on propeller combat was the Football War of 1969). Both sides would be poorly equipped. This was realised by the Holidian Government immediately post-war and as such, the Holidian Army spent more on upgrading their forces.

Background
The Holidian Empire and all it's territories suffered greatly from the 2008 Economic Crash. Taxes went up and a lot of spending had to be cut. Because of this, Ukraine; the Holidian Empire's largest territory at the time, threatened to use force if they were not allowed to become independent. Reluctantly, the Holidian Government folded and on the 14th August, 2009, Ukraine became an independent nation.

As both nations steadily recovered in the decades to come, Ukraine spent more on improving and increasing their military. Knowing the Holidian Empire was still poorly equipped, Ukraine invested in locally producing the Australian-American Aus Fighter IV, and buying old M60 tanks from the US. Tensions began to rise between the two nations as Multiple Ukrainian Military bases were established on the border bordering west of the Holidian Empire. Both nations began increasing military strength during the 2020s. Both nations were poorly equipped for a war, though, Ukraine was stronger in terms of air power whereas, The Holidian Number had better tanks.

The war would begin as 20 Ukrainian Aus Fighters violated Holidian Airspace on September 9th, 2028 at 2200 hours.
