My 2 cents:
- M48's -> Straight to the scrap yard. These tanks are older then old. Considering what is happening to Syrian T-72, it would be pointless to keep a tank thats even older and more inferior then that in storage or service.
- M60's -> Turkish army has a tradition of having a huge stockpile of tanks in storage, so replace the M48 in storage with these i say. They can always be used for something.
- M60T's -> Should ofcourse remain in active service. I think this tank would be perfect for the upcoming LCT, LHD and LST naval ships so it can be used for landing. The tank is small, modern, not that heavy and is extremely capable.
- Leopard 1's -> Just like the M60's they should be stored away.
- Leopard 1T's -> These tanks should remain in limited active service, these can definitly have an impact in any battlefield considering their modern FCS.
- Leopard 2's -> These tanks arent that old and can still go strong for another 2 decades. I'd say overhaul and upgrade them with the NG package. Station them at thrace.
