OK
Found this shot below the one posted the other day.
Information is not clear but I suspect the tank beside the basic 2A4 is the Altay and what's in the parade is the Leo 2T.
One thing is clear they are not the same tank and the top photo beside the 2A4 is more refined. I picked up that photo from a Turkish blog. Needless to say, I don't read Turkish so I don't know what the text said that accompanied it and now I cannot find the website again....
However... if the top photo is indeed the Leopard 2T ( Next generation )then what are the ones in the parade........
AH HA !!

It **appears** that the lower photos is a parade of Singaporean Leopard 2SG and they were ( I'm guessing ) Used to compare to the 2T
