>completely forgotten in former Soviet bloc.
That is mysterious, because Red Army in WWII had liek 28 cavalry divisions.
>shooter
We also adopted that naming. First "shooter" battalions appeared in the 1947-48 order of battle, still in infantry divisions, but from '48 those were renamed to "shooter" brigades (with motorized infantry, mechanized artillery, AA, assault gun, and tank sub-units), then turned into divisions.

>our "armored infantry" (M113s) would in another country be just mechanized infantry
>But then what would the 100% wheeled APC units be called?
I think the naming of the Brazilian units armoured and mechanized came from the fact that they had to make distinctions between differently equipped (maybe because that equipment they had, and/or they served different purpose) units.
>was absorbed into the armored branch
Airmobile units were formed from cavalry ones too.
