Differentiating Ground Radar pings

i think there's always the urge to see as much detail as possible
but to be honest most of the time you can easily deduce the stackcompositions based on the newspaperreports and buildings in the homeland, so there isnt really any need to add any more detail to radars

after all if you really wanna know there are specops/drones for that
or you just kill it and then look into the newspaper to see what the stack was made out of

Differentiating between choppers and airplanes makes kind of sense, because they can differentiate by speed and flight hight, I suppose.

Differentiating between infantry and armor/mixed, does not feel that important.
The only intersting might be having different ping sizes depending on stack size. One lonely infantry will only make a little blip, while a full stack with a lot of armored units will give a huge blip?
