So, I'm playing as Muscovy->Russia. At the beginning, Russian armies have generic names (1st army, 2nd army, etc.) But from some recent point (I believe that it was when I completed the collect Yasak mission) the armies have started to be named with less generic names (Russian Imperial Army, Army of Poland, etc.) This is a nice change to me, as I find the generic names for the armies totally uninmersing. However, I would like to know what triggered the new names, so that in other run, I'll be able to trigger it sooner.
