"were upgrade Tirans" In the sense that they were Achzarit built from Tiran chassis, then yes.
I remeber several pictures posted on tanknet of a badly mauled Achzarit. But as actual tanks they are long gone, that is what I read everywhere, from websites to posters.
Considered the obsolescence and the potential for fratricide it makes a lot of sense. Judging from the pictures posted the bulk of the tanks committed were Merkava III and some uparmored Merkava II. A few Merkava IV were used as well.
I have a picture of a Merkava (not sure if II or III) which suffered a catastrophic ammo explosion (turret popped T-72 style and rear hull gone). Needless to say my appreciation for the Abrams ammo storage has increased since then.
