Actually Rorke may have a good point here. Sabra upgrade was heavily criticized by many Turkish defense analysts too, and I do see and understand their argument. But let's not forget that all of the countries who border Turkey to the east use very old Russian junk and Sabra is more than enough to slaughter what, say the Syrians, may throw its way. Turkey recently also purchased a lot of refurbished Leo 2A4s from Germany and has thousands of M60s with the Volkan upgrade (thermal sights, new FCS, computer, etc). All this is a stop-gap measure until the new Turkish Altay MBT (which will likely look very similar to the XK-2) rolls out.
