About as well as it would against a company of M1A2 SEP, M1A1D/SA, or Leo2A5/A6.
It seems to be a good tank for Croatia's needs, and I am not slagging on it, but to say it would "hold its own" against those tanks is a bit of a stretch. But, it doesen't need to fight the top of the line tanks of the world so the point is mute.
The comparisons made in those youtube videos don't even say anything.
I'm glad it has the whatever the Croatian version of FBCB2, whatever they call their BLUEFOR tracker. I don't like the fact that the Commander's Independent Viewer seemed to be an afterthought, and it was added as part of the Israeli designed CWS (Commander's Weapon Station) Sure the TC has an independent optic to search for targets, but it is not the same optics as the gunner, and he has no way to designate targets and transfer them over to the gunner. In the modern tank fight (especially in the defense) this puts crewmen of this tank at the disadvantage when fighting modern Westarn tanks.
