Other states in the Middle East have modernized and upgraded their older tanks for similar reasons.
For example, Egypt has a large arsenal of vintage T-54/55 and T-62s, many of which it has in storage. Cairo successfully prolonged the life of some of its T-54s by heavily modifying them and making a new variant called the Ramses II.
The Ramses II is a T-54 outfitted with both the engine and gun of the American M60, of which Egypt operates well over 1,000 of to this day.
Iran has also modified and built its own version of various tanks for years now. Beginning in 1996, it began building the Zulfiqar family of tanks. Three versions have been built to date. Iran likely developed the tank from components of older American M60 Patton and Russian T-72 tanks, both of which Iran has operated over the years.
