I know this is on another thread but, since I posted on this as well here well you know...
The following site shows two videos from "Future Weapons" on Discovery Channel. The first one validates that the "Merk" from the beginning was designed for the role of carrying infantry on board and acting as an ambulance. I recognize this is secondary to crew survivability. The second video is well worth watching as as covers the updated capabilities of the "modernized" MK IV with it's new ammo round. Note Germany is fielding a new round similar to this on the latest version of the LEOPARD 2A7+ which is being done now as well. I'll have more on both for my first submission for the "Fall Campaign". Enjoy the videos, they're safe my computer didn't blow up!!
