Yes, the portraits look cartoonish but, before removing them, one should be reminded that they serve a purpose: showing what kind of troops man that particular subunit (Heer, Luftwaffe, Waffen SS, ordinary riflemen, Guards etc.).
But I guess that this particular piece of info is also given by the counters' colours.
Today I noticed that there is also a 'national' icon on the unit for each of the different manpower types (Heer, Luftwaffe, Waffen SS, ordinary riflemen, Guards)
Which icon do you mean by that pls? Just maybe not seeing it properly...
