The PRC is way ahead of this. Those soldiers know what will happen to their families if they defect. They knew that when they left: Come home alive or come home in a body bag, but if they don't come home, their families will die in a labor camp. The PRC in Ukraine are handpicked and selected for the equivalent of special forces units. They have over fifty years of generational, societal programming of mistrust and malice towards the West. I do not anticipate many, if any, of them switching teams.
