When troops under encirclement or low morale, histroy does tell us they defect or flee. Then will it be possible that we can capture and welcome them to our armies. Not only land units, maybe naval(ships suffering from very heavy mechanical damage) or air forces(out of fuel on the way of going to a friendly base) too. As far as I know this was how CPC won the war in Chinese civil war. She did this by being the friend of people and make herself popular. I do hope this can be a turning point for CPC in HOI3 too.
Maybe paradox can make them not listening to the superior under fiece stiuation too!
