Wow it does that much? Now that sounds interesting... I thought it would act more like the British Radio Triangulation ability in CoH1 so I never tried it.
it works best if you are used to the German GUI sounds and the sidebar notifications.
note just found out it also shows you when unit upgrade. i had a flamer pioneer upgrade message on my side. uploading a video soon.
things i noticed, you get the verbal panzergrenadier message right away. but the writen message is in line so it comes later, i got confused in the video and looked for a nonexisten pgreen. all the sounds you hear in the replay are from the soviet side of the game.
