The AN/PAS-13B thermal weapon sight (TWS) is an infrared sight developed for the United States military by Raytheon. The sight is designed for use on small arms in the U.S. military's inventory, but it can also be used as a standalone observation device. The AN/PAS-13B uses thermal imaging so that it can be used day or night. Thermal imaging also allows the sight to see through smoke or fog, things that may normally obscure other night vision devices. The AN/PAS-13 first became operationally capable with the U.S. Army in 1998 and has reached a total production of 33,400 units.^[1]
