I don’t think this kind of a discussion is healthy.
I don’t think that Israel had 200 or more fully unique independent tank or armoured vehicle projects. Most were modifications of earlier projects.
Almost no nation in the game could really have 200 fully unique vehicles if you don’t count modifications or developments from a previous platform.
The other extreme is also very unpopular on this forum: considering every modification on a vehicle as a unique vehicle (which would be the textbook definition).
Both Israel and South Africa had a very large amount of projects where they either built their own domestic designs, modified foreign designs or modified imported equipment. South Africa even has a rather large time period advantage, as they can reach from vehicles from the 1930s as well.
Either way, both countries could be easily a separate tech tree with over 200 fun ‘unique’ vehicles.
An example of a more unique tech tree for Israel: Israeli Expanded Ground TT (by @CaID )
South Africa: South African Expanded TT (also by @CaID )
There are also more recent and complete discussions about this on the forum.
