There are absolutely no terms or conditions or restrictions or whatever on Leopard 2A4's purchased by Turkey and they are well in shape except the inital problems encountered (and eventually fixed). The talks on a second batch of 41 tanks finalized and they are going to be selected from reserves. From the very beginning they were planned to be purchased for NorthWestern Turkey, i.e Thrace Region, to counter-balance the modern MBT threat posed by Greece by the induction of Leopard 2A4 and A6's as an interim solution until the critical date, which is around 2012. This is the year when all Greece's Leopard 2A4 and A6 tanks will enter service and become fully operational. Thus, surplus Leopard 2A4 purchase was meant to stop the critical MBT gap until the new MBT starts entering service. The MBT project already delayed 1-2 years now, so the additional 41 tank-purchase can be seen to fill this additional gap.
M-60T modernization was for the tanks in South - SouthEastern sector, to face the threat posed mainly by T-series tanks. MBT's have secondary role in the ongoing Low Intensity Conflict in SouthEastern Anatolia / Northern Iraq, so they are primarily -not solely- for the Southern Sector, i.e Syria.
