The BlackHawk Night-Ops Gladius is the most innovative handheld tactical illumination tool to ever arrive on the scene. The Gladius will revolutionize the way you think and operate in hostile reduced light situations. There has been nothing like it on the market before. Don not let its somewhat familiar exterior lead you to some early false conclusions! This is not your ordinary flashlight. From its inception, the Gladius was designed from the ground up to be immersed into the realities of close quarter conflict and should significantly enhance the capabilities of those operating in low light environments. The Gladius is born of years of operational & low light training experience. We have spoken to and listened to those that go into harms way on a professional basis. Based on this constant dialog, the unique capabilities of this feature rich package simply outclass the competition.
