Well, I'm trying to learn the tools right now, but here's my basic idea for the story:
In 1980 Solidarnosc, an anti-communistic movement is formed in Poland. In 1981 the socialist government attempt to destroy the organisation via martial law. The plan backfires as also the military dislikes the socialists. The legendary "hidden war" breaks out as the anti-socialistic military enters Warsaw to overthrow the socialist government. Despite parts of the military and police still being loyally defending the parliament, people unknowingly wake up on december 14 1981, finding themselves in the Solidary Sovreign State of Poland (SSSP). Knowing of the imminent threat from the Soviet Union, the Polish government attempts to find allies. NATO refuses Poland membership due to the risk of starting a new world war.
On december 18th, Sweden agrees on an alliance. As a gesture of good faith, Polish troops are stationed at Gotland and Swedish troops get stationed at the Polish-Soviet border. On new years day the Soviet Union enters Poland, only to enter Sweden two days later.
I've made some investigations to see what aircraft the nations had back in the 80's and here's what I've found:
Polish Aircraft
Mig 21
Mig 23
Mig 29
Su-22
Swedish Aircraft
Lansen
Draken
Viggen
SK60
Soviet Union
An-12
SU 7
SU 15
SU 25
SU 27
Mig 21
Mig 25
Mig 27
Mig 31
Mig 23
Tu 128
Yak 28
I'm going to attempt to make the pack contain as many of these vehicles as possible, but since I'm a nice guy I won't add anything without the creator's permission. Since I'm new, there's quite a big likelyhood that I'll be asking what to do. The campaign will also contain some custom terrain.
