What's this turret?

[Wdll]

From a recent training exercise. I don't know if it is the angle and the light or something, but it doesn't look like a 12.7 to me. Or is it? If not, what is it?

I am talking about the turret on this, I think it's a Leonidas version APC.

ok never mind, it's probably a 12.7 after all.

Does look deceiving, but it's a 50cal
The Greeks did have a 25mm and 30mm upgrade planned but I don't think they have the funds to carry this out.
