Ha Ha...name this tank!

Looks like a Merkava to me, a 1 or 2, not sure about that. You can see it has 6 road wheels and if I'm not mistaken the Abrams has 7. It also has the distinctive extrusion (hope that's the right word) on the sides of the turret just above the hull. The there's the barrel, you can see that there's still a bit of turret ahead of where the barrel is elevated. That's typical for a Merkava too.
I think it's a Merkava 2 as it has the extended rear end of the turret and the turret seems a bit wider than the 1 has but it still seems to be equiped with a 105mm gun. So I'm going for the Merkava 2.
