Abstract: This experiment evaluated the tactile and visual identification of the XM106 bursting smoke grenade in a variety of situations representing the typical handwear and eyewear configurations of dismounted Warfighters. Thirty-six test Soldiers participated in the evaluation from 17 to 25 September 2009. After being trained on the visual and tactile features of the XM106 bursting smoke grenade and the M83 smoke grenade (with and without a "pull safe" device), each Soldier completed tactile and visual identification performance trial exercises. Tactile identification trials had Soldiers identify grenades by touch alone, using bare hands; contact gloves; nuclear, biological, and chemical (NBC) gloves; and cold weather gloves. Visual identification trials had Soldiers identify grenades using normal vision, the Enhanced Night Vision Goggles, the AN/PVS-14 night vision goggles, the NBC protective mask, and the ballistic laser eye protection system with tinted lens. Performance trials included identification under a cognitive load (while operating a robot) and identification while under a physical load (individual movement techniques). The XM106 was also evaluated through the use of Soldier questionnaires and observations from representatives of the U.S. Army Research Laboratory, Human Research and Engineering Directorate. Findings indicated that the XM106 bursting smoke grenade could be readily distinguished from the M83 smoke grenade under all handwear and eyewear conditions.
