Second, in many countries operating 60+ tonne vehicles is simply impossible, while 30-40 tonne range is still viable. On the other hand, even in the 60+ tonne "mainstream MBT" range, you can't make "indestructible" vehicles anymore, especially when the enemy has modern AT means/ATGMs. Modern layered, modular, reactive armors offer decent protection in the 30-40 tonne range, especially when combined with ASOP systems.

The vehicle is however too heavy for the Indonesian tank program, weighing up to 43 metic tons. The first model of a modern Marder-based tank was presented at Eurosatory 2012 (nicknamed " Marder Medium MBT") and was a more comprehensive upgrade of the Marder, featuring the Oto-Melara HITFACT turret with a 105 mm rifled gun, thick AMAP composite armor modules for protection against RPGs and EFPs, a mine protection kit and an uprated engine. Rheinmetall is offering a new version of the Marder medium tank. The MMWT is also fitted with a mine protection kit of unknown protection level. This would mean all-round protection against 14.5 mm AP ammunitions or frontal protection against 25 mm medium calibre rounds.

Neither the protection levels of the MMWT nor of the Kaplan IFV has been disclosed yet, but a ballistic protection meeting the STANAG 4569 level 4 or the level 5 standard seems likely. Protection is provided by the steel construction and further applique composite armor modules, which are mounted at the front and at the sides of the vehicle.
