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 ...
The Siege and Destruction of Jerusalem by the Romans Under the Command of Titus, A.D. 70, by David Roberts (1850), shows the city burning. Early thermal weapons, which used heat or burning action to destroy or damage enemy personnel, fortifications or territories, were employed in warfare during the classical and medieval periods (approximately the 8th century BC until the mid-16th century AD).
A thermographic weapon sight, thermal imagery scope or thermal weapon sight is a sighting device combining a compact thermographic camera and an aiming reticle. [1] They can be mounted on a variety of small arms as well as some heavier weapons. [2] As with regular ultraviolet sensors, thermal weapon sights can operate in total darkness.
Another Trijicon scope marked with 1 John 1:7: "But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from all sin."

Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.

The optics are considered exceptional, even by contemporary standards and the biggest drawback compared to modern scopes is the weight. Although the AN/PVS-4 has not had a great deal of cultural impact, its legacy of high quality night vision has become a staple of movies and television shows which often do not show real equipment.
The Greeks and Romans both made extensive use of artillery for shooting large arrows, bolts or spherical stones or metal balls. Occasionally they also used ranged early thermal weapons . There was heavy siege artillery, but more mobile and lighter field artillery was already known and used in pitched battles, especially in Roman imperial period.
