As far as I know, Standard Bio only marketed it, it was still L3’s M60 Destroyer.
Considering both of them are premium it not much of a problem. Even if they were Tech Tree vehicles, they could be hidden similar to Italian aircraft in German Tech Tree.
You are probably mixing it with Sabra. M60 AMBT was marketed by Standard Bio in Turkey.
Israeli modernisation is Sabra, which was chosen by Turkish Armed Forces and some 170 M60A1 were upgraded to Sabra Mk.II standards, designated as M60T. Modernisation was planned to be continued with M60A3 but Turkish-Israeli relation got soured and project completed with initially ordered 170 M60A1. Turkey did order Leopard 2A4s from Germany around same time.
We also got a suggestion for that one too. M60A3 Next Generation (P). Still being tested by Turkish Armed Forces, this version we’ve seen is lacking some elements, so I’ve opted to suggest it as is and will be suggesting production version too.
Italy already has two nation, isn’t that enough ? Before adding anymore half completed stuff, they should be adding unique Hungarian & Romanian vehicles.
Can’t say for all Italian TT playerbase, but it would be nice to see more Italian stuff, it isn’t like there is nothing left to add.
Plus if they add Turkish subtree it’d be another focus on high tiers with a lot of copypaste, but Italian TT is seeking for low-medium tiers additions way more imo.
It’s far from full, but yeah, actually if they cared to add more stuff for Italy, it wouldn’t have enough space.
Although Gaijin’s added Switzerland as a German subtree and their ground TT is way more filled than Italian one.
Some TT reworks were in the leak as well btw, so maybe they will make big nations even bigger.
Of course for Turkey the best scenario would be to add it a standalone nation, because if it comes as a subtree it would be treated as a filler.
