And what about the Tiran 4/5 tanks ? They were captured T54/55 which Israel used a long time first without much modifications , later with new turrets / armor improvements and now because they became obsolete they removed the turret and built their APC Achzarit out of them . This is very inventive as i wrote and you say they didn't employ them .

My apology. I was wrong about that. I was unaware of the Israeli Tiran series tanks, as they were all withdrawn from service by Israel before I served in the US Army. (There was Tiran 6, also, which was a captured T62. Israel never had more than 100 of these.)

The Achzarit has been so heavily modified/rebuilt that it hardly counts. About the only thing that's original is the base hull and road wheels. The suspension, engine, controls, weapons, and pretty much everything else has been changed. The only thing the Israelis have done by re-using the base chassis is save themselves the cost/effort of casting a new hull. Still, technically you are correct in that they did use them since rather than casting a new hull for a new APC they reused captured hulls.
