I don't get the fuss over KCH tbh, even if they were objectively very OP in many roles which they aren't (you've actually balanced a new unit better than Relic, congrats) the unit still wouldn't be an issue because Ostheer and the nature of the rest of the commander.
While this would be impossible due to media reasons, a speaker upgrade available on the Skdz 251 halftrack that can inflict a temporary negative aura on units it targets through the fog of war (functioning like IR track) would be a neat substitute for Propaganda War. Combined with the command tank and KCH it could lead to greater offensive potential while still retaining the theme and mild defensive utility.
Overall though I'm really impressed at the legitimacy of your thread and I hope it inspires Relic. 
Thanks for the response, and Cuddletronic did send my ideas to Relic's balance team
. I'm probably going to be keeping propaganda war, which gives this doctrine an emergency response to an incoming allied blob. The speaker idea does fit this doctrine, but for now, I'm probably going to stick with what's worked before in coh1, considering a call-in ability is a lot easier to balance/maintain than another unit that has special properties; nevertheless, it's still a great idea that I would happily consider if I had an extra spot in this doctrine.
