This article reports the findings from an experimental investigation of effectiveness of control force measures using simulated non-lethal weapons in a crowd management situation. The Crowd Behavior Testbed is a 6,000 square foot facility housed in the TBRL. The laboratory is fully equipped with a comprehensive suite of experimental controls, computer hardware and software, cabling, devices that are sources for stimuli, and means for data capture. Two different types of weapons that were suitable for crowd situations were chosen after a test phase. The simulated hand-to-hand combat weapon chosen was a foam sword used in martial arts. It has a 10 inch handle and 25 inch long foam area. The simulated stand-off weapon shoots a foam dart the magazine holds 10 darts. The ends of the baton and the ends of the foam dart were covered in chalk to mark impacts. Subjects were tasked with throwing rocks into targets on a M1008 Commercial Utility Cargo Vehicle CUCV. Each successful throw was awarded points and dollars for the group. The armed control force stood between the crowd and the CUCV. Subjects also were tasked with avoiding being hit with the hand-to-hand combat weapons and the projectiles from the stand-off weapons. A 2x2x2 within subjects factorial design was employed with the two levels each of Weapon Hand-to-hand or Stand-off, Number of Control Force One or Many persons, and Threat No Threat or Threat. Hypotheses Compared with the condition of One Control Force, the Many Control Force condition will have fewer successful target hits and more bean bags not thrown. Compared with the condition of No Threat, the Threat condition will have fewer successful target hits and more bean bags not thrown. Compared with the condition of Hand-to-Hand, the Stand-off weapon condition will have fewer successful target hits and more bean bags not thrown.
