From the notice

This Special Notice is to advise intrested memeber of the Training and Readiness Accelerator II (TREX II), as well as other intrested members within the U.S technology base, that a Request for Solutions (RFS) has been issued by Advanced Technology International (ATI) to develop a training device of the 120mm Mortar Training Sytem. The purpose the Training Readiness and Aceelerator (TREX II) is to spur innovative development, demonstration, and expedited delivery of prototypes to increase Warefighter readiness via modeling, simulation, education/ training, expermental validation, and miltary readiness focued projects. A constorium has been establised to develop prototypes presonnel and the support the platforms, systems, components, or materials proposed to be acquired or developed by the Department of Defense (DoD) or to improvement of platforms, systems, components of materials in use by the Armed Forces. Link for TREX II- [link] Objectives:STE LTS is seeking a training system for 120mm mortars in both the Armored Multi-Purpose Vehicle (AMPV) and Stryker M1129 Mortar Carrier that: 1. Mortar crews can install and de-install. 2. Time to install and de-install is less than five minutes each. 3. Allows the use of a training round between 25 and 35 pounds. 4.
