claims 550 mm pen for the Kombat ATGM..

The T-72AMT has been adapted to fire the 125 mm Kombat (Combat) gun-fired laser-guided missile, which is capable of penetrating 550 mm of armour

..other sources say 750

the gunner has now also a night vision sight used to fire anti-tank guided missile able to penetrate 750 mm armor at the distance of 5 km.

I read the text in the first link (don't know if it has been updated since you wrote your post)

...gun-fired laser-guided missile, which is capable of penetrating 550 mm of armour itself protected by explosive reactive armour (ERA).

that it is 550 mm after ERA and 750mm mentioned elsewhere is penetration without ERA. Sometimes I see numbers like that listed for USSR ammunition such as for PG-7VR:

"PG-7VR is a 64/105-mm tandeam HEAT rocket. It has effective range of 100 m against tanks and 200 m against stationary targets. It penetrates up to 600 mm of armor behind ERA and 750 mm without ERA;"
