Abstract: The primary purpose of this effort by the U.S. Army Research Laboratory (ARL) was to record Soldier-participant comments, impressions, and any recommendations for improving the guided multiple launch rocket system (GMLRS) in areas related to the design of the rocket itself and the training required to handle, maintain, and employ it with the use of the high mobility artillery rocket system (HIMARS) launcher and its associated support vehicles. The GMLRS was tested along with the HIMARS in a combined initial operational test (IOT) administered by the U.S. Army Test and Evaluation Command (ATEC). Three of the four multi-faceted questionnaires developed for the combined HIMARS-GMLRS IOT provided Soldiers with the opportunity to address GMLRS-related issues. These instruments were the military occupational specialties (MOS) 13M (MLRS crewman), 13P (Fire Direction Specialist), and 27M (MLRS Repairman). Results from this evaluation were used by ATEC (for the GMLRS system evaluation report) and ARL's Human Research and Engineering Directorate (for the human factors evaluation), in support of the Milestone C decision for full-rate production that occurred in June 2005.
