This Special Notice is to advise interested members of the Training and Readiness Accelerator II (TReX II), as well as other interested members within the U.S. technology base, that a Request for Solutions (RFS) has been issued by Advanced Technology International (ATI) for Small Arms Orientation Device and STE LTS Indirect Fire. The purpose of the Training and Readiness Accelerator II (TReX II) is to spur innovative...

The weapon orientation device critical objectives include: accuracy to engage a human target at 1000 meters out to engaging a vehicle at 5000 meters; accuracy is not affected by training conditions such as metal or electromagnetic interference; easy to calibrate the system and infrequent re-calibrations required; ability to lead and elevate over a target; and ability to engage in low light or no-light conditions. In addition, the following are objectives providing trade space in the prototyping efforts: size and weight less than the current laser small arms transmitter, a 72-hour battery life, ability to engage through concealment and obscurants, and the ability to fire multiple round bursts.
Desired Objectives
At the firing unit (howitzer or mortar), the training device must collect all information needed to correctly replicate a firing event in the instrumentation system. The device must require minimal setup and tear down effort on the part of the unit.
The instrumentation system requires a tap into the digital gun data. The instrumentation system can use gun data to replicate indirect fire effects in a training event.
The forward observer must see the “notional” round impact near real time and with sufficient accuracy allowing the forward observer to adjust round impact. The forward observer may use different devices such as binoculars or Joint Engagement Targeting System (JETS).
The Department of the Army, through the W6QK ACC-Orlando office, has issued a Request for Solutions via Advanced Technology International for the development of the Small Arms Orientation Device and the STE LTS Indirect Fire. This initiative, identified as solicitation TREXII-26-04, is managed under the Training and Readiness Accelerator II (TReX II) to deliver prototypes that enhance Warfighter readiness through modeling, simulation, and experimental validation. The project is classified under NAICS 541715 Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) and PSC 6910 TRAINING AIDS. Responses for this special notice are due by July 9, 2026, and the primary place of performance is Orlando, Florida.
The scope of this prototyping effort encompasses two distinct technical areas focused on mission effectiveness. The Small Arms Orientation Device aims to produce a weapon orientation tool accurate enough to support ballistic model-based engagements at ranges from 1,000 meters for human targets to 5,000 meters for vehicles. Requirements for this device include the ability to penetrate concealment and obscurants, a battery life of at least 72 hours, and a form factor that does not exceed the size or weight of current laser small arms transmitters. Technical objectives prioritize infrequent re-calibrations, immunity to electromagnetic interference, and the capacity to engage targets in low-light or no-light conditions across 12-month periods of performance.
The second technical area, STE LTS Indirect Fire, focuses on replicating firing events for howitzer and mortar units within an instrumentation system. These devices must integrate with digital gun data to simulate indirect fire effects in near real-time, allowing forward observers to adjust round impacts using standard equipment like binoculars or the Joint Engagement Targeting System. The prototype systems require minimal setup and teardown effort to facilitate training operations. Detailed project goals and final objectives will be coordinated between selected vendors and the government to ensure the prototypes meet specific accuracy and interoperability standards for the Department of Defense.
