AN/PAS-13 Thermal Weapon Sight
The AN/PAS-13 Thermal Weapons Sight (TWS) is a portable infrared sensor that can be used to aquire targets at long range, at night and during the day. It is a passive system which means it does not emit any signals that can be detected by the enemy. Unlike image-intensifier systems, a thermal sight is not susceptible to 'bloom' issues ie being overwhelmed by sudden bright sources of light.
The PAS-13 comes in light (v1), medium (v2) and heavy (v3) versions. The v1 is typically fitted to weapons such as M16 rifles or rocket launcers such as the M136 (AT4). The v2 may be mounted on light and medium machine guns such as the M249 or M240. The v3 is typically mounted on longer range systems such as sniper rfiles, M2 machine guns and Mk19 grenade launchers.The sights feature a data port that allows them to be connected to external equipment such as recording devices. Various recticules can be programmed into the units depending on mission needs. The sights run on disposable lithion or rechargable lithium-ion batteries.
The AN/PAS-13 is used by regular and special operations units alike. The Marines of 1st Recon, for example, carried AN/PAS-13 sights with them when they spearheaded the invasion of Iraq in 2003.
