Unit type indicators

So I was trying to decipher what those little yellow and white symbols mean at the top of unit cards. Obviously the bow is ranged units, the spear is spear units, and the sword is melee attackers. But what is the difference between the shapes (square/diamond/circle) and the backgroud color (all yellow/half yellow half white)? Maybe I'm looking too far into this, but I was just curious.

I THINK it have to do with weight class. Circle is light units, diamond medium and square are heavy.

Makes sense, but what does the half white, half yellow color scheme mean?

Weeelll... I would also like to know exactly what the icons mean.
Would be grateful for another more detailed reply :)

Ok here's the system.

Circle: light/ very light units
Diamond: medium/ heavy units
Square: very heavy/ super heavy units

The half white unit markers denote cavalry.

The whole system is not super useful to me, to be honest.
