All sources I can find state that MLVM vehicle should have KPVT in turret instead of 25mm cannon. I've changed the weapon in first slot to 56 with 50HE/25AP load and adjusted fire control to 2 and range finder to 3.
The upgraded version with cannon is called MVLM-M and available around 2005 but seems to exist only as a prototype.
