So I was going for the Little Entente achievement which failed horribly because Germany "Danzigged" Poland (should've let them lose...) but later as I was hoping World Tension would spike a chain of events occurred resulting in me having volunteer units on both sides of a war:
Chain of events: Italy Axis (Italy+Bulgaria) DOW on Allies. I send volunteers to UK and Greece. Japan joined Italian Axis while still fighting China. Soviet warmongering period begins: DOW on Afghanistan, then Japan and Axis, then Iraq. Send Volunteers to Iraq to increase WT and stem red tide. Iraq joins Axis, Iraqi war merged with Axis-Comintern war and Axis-Allies war and end up with Volunteers on both sides with no option to recall. Some months later Italy and Bulgaria capitulated and my UK and Greece volunteers deploy in Egypt and push back to Iraqi borders, during this time my volunteers in Iraq have been holding the two ports on the Iraqi coast killing thousands of allied would-be naval invaders, I never did see if I could fight myself which I regret (no chance either now, ironman), but Iraq capitulated and those volunteers finally got to go home. Afterwards, funny but unrelated: Romania turned Fascist, left my faction, joined Axis, immediately got devoured by both Allied and Comintern forces.
Dear Paradox, probably need an option to recall volunteers.
