The Robotic Evacuation Vehicle (REV) developed on the RCCEE program was a first-generation proof of concept vehicle that showed that it could serve as a force multiplier for removing wounded soldiers from harm's way and safely evacuating those soldiers to a point where proper care could be administered. However, during testing and demonstration, there was significant feedback as to the suitability of this concept on the battlefield. As the REV vehicle was designed to be completely unmanned, the most significant piece of feedback was that the Army would not, at least within the foreseeable future, allow wounded soldiers to travel in a vehicle without a human medic or attendant on-board to tend to the soldier.

Based on this feedback, and working with both TARDEC and TATRC, Applied Perception developed a three-module concept for medical transport that could be installed on the TAGS-CX vehicle. The system consisted of a center medic/attendant module that provided space for the on-board medic, as well as two patient transport modules on either side. The medic/attendant module included a seat with headrest and independent suspension system to isolate the medic from the dynamics of the TAGS-CX vehicle. The module is designed with removable side panels which allow the medic module to be used without either of the two patient transport pods installed. In addition to the basic patient transport capability, the medic modules also included controls for an on-board operator to see around the vehicle and drive it manually.
