This document discusses armor upgrades and capabilities for NLMB tracked armored fighting vehicles (TAFVs) for urban combat missions. It proposes 7 layers of protection for the TAFVs through add-on armor, including spall liners, thick armor plating, ceramic tiles, reactive armor, pre-detonating racks, and gunshields. It argues that TAFVs can accommodate more protective layers than wheeled vehicles. The document also describes vertical assault capabilities for TAFVs using a boom arm to deliver infantry to buildings, and discusses missions focused on rapid deployment for urban operations.
