The Israeli Ministry of Defence is considering the development of a new heavy APC dubbed Nemerah (Tigress), based on the Merkava MBT, as was reported in Jane's Defence Weekly. Israel has a range of heavy APCs converted from old MBT platforms.
opswarfare agrees that a normal APC /IFV, with armour that is only thick enough to protect against small arms fire, is inadequate for modern warfare, especially urban warfare, where RPG and IED threats exist. We have seen this scenario played out in Palestine or Iraq; a lowly RPG can take out a APC.
Russia is the other country with this type of vehicle in development, BMPT & BTR-T.
