If we do have M60A3, it should be upgraded to Israeli Sabra MkI
standard.

One thing from here :
http://www.israeli-weapons.com/weapons/vehicles/tanks/sabra/Sabra.html
The Sabra Main Battle Tank is modernised upgraded M60A3,
developed by Israel Military Industries Slavin heavy weapons plant
at Ramat Hasharon. As with all upgrade programs the scope of a
Sabra upgrade package is customised to meet a particular
country's operational requirements.
Which country????

As above, Sabra MkI was unveiled in 1999, Turkey started
negotiation of the Sabra upgrade in 2000 and was later offered the
Sabra MKII, not Sabra MkI which was actually designed for certain
country, so which country again????
