So with the help of @Sgt (Ret) Grimm I tweaked an existing Chernarus Liberation mission for a for a Post WW2 faceoff between the good ol' US of A and the SU also known as The Patton Plan. I also recently just finished the GER vs SU template or Operation Barbarossa. Next up will be a GER(DAK) vs US(NAC) most likely on takistan
Currently it requires 3 additional mods IFA3 FOW IFA3: Liberation (Note its called liberation because that is what the standalone game was called)
The mission files are The Patton Plan (United States VS Soviet Union on Chernarus) Operation Barbarossa (Germany VS Soviet Union on Chernarus)
Right now there are some small bugs/issues. If anyone notices any other bugs please post below so I can get a chance to fix them.
There are no spawnable friendly infantry in the template because they will spawn as independent and will engage you immediately after spawning in.
The US faction doesn't have AA,AT, or Artillery guns so they borrowed the AA and AT guns from the Germans. and they use the RHS US artillery because artillery hasn't drastically changed over the years.
The GMC Tent doubles as a mobile respawn while the GMC Ambulance doubles as a fob box.
