Czechoslovak ground tree

DANA, Topas and SKOT were created in Polish-Czech

DANA was just Czechoslovak SPGH project, Topas too. Later modernization made by Poland should only go to Poland with the only exception being export vehicles.

@Grzegames

Ryś is a modernization of SKOT, so it also counts

Yeah, no.
Only “Czech” thing about Ryś is that SKOT was joint project between Czechoslovakia and Poland. Ryś was full on heavy Polish modernization so it should only go to Polish tech tree. Not both and not only to Czechoslovakia.

I actually made a mistake. However, this suggestion is about the Czechoslovakian tech tree, so they may get Polish variants of export vehicles.

Besides DANA M2, none of them are export versions from Czechoslovakia or post-velvet states.
