An Algerian branch could provide unique variants and export modifications for the USSR trees, a few examples below

They should at best be a bunch of event vehicles, the BMPT-62 would be interesting as such.
The least Russia needs right now is even more depth by a sub when it’s the biggest nation/tech tree in the game, and the same goes for the other two big nations after it (US/Germany).
Algeria would be fun.
The T-72M1M exported to Algeria would be great for filling that 9.3-10.3 gap.
Please don’t compare Germany to the US and Russia in terms of how many vehicles they have. Iirc the Brit’s have more overall and even France has a similar amount(with I think Germany having more)
Algeria or Iran would be cool
Algeria and Iran (post-revolution) would be nice @Fjord said to have in the USSR tech tree. Personally I don’t think there are any spaces to fit a sub-tech tree. Given the amount of vehicles there are very few spots to fill vehicles with and I think that USSR doesn’t lack options to be added before any concept of sub-tech tree.
I also think that USSR should be considered a sub-tech tree in the format of a tech tree. USSR is a bloc of nations not essentially on Russia. Other ex-member of the Soviet Union should be priority if a sub-tech tree is ever considered to be added to USSR in the first place.
Including subtrees. As standalone trees, Russia is arguably the biggest. And it’s also unfair to compare France and G.B (nations with generous additions from other countries) to entire nations with mostly indigenous vehicles like the ones I mentioned.
