many old systems on SAA tank have proven to be unreliable and unsuitable for urban warfare among them is the TPN-3-49 night vision sight on T-72 tanks ,as SAA T-72 tanks start to take on the streets it become clear that protecting the IR lamps from the enemy fire is impossible just like the idea of fixing it again and again
after two years into the fight most of the tanks in urban area have lost it's night capabilities with all or almost all of it's IR lamps broken some even the TPN-3-49 night sight it self .
when the Syrian scientific research center was tasked with finding a solution for this problem in 2013 they were fast to come with an idea for the perfect replacement
a thermal sight ,as thermal vision don't need illumination ,and they have already some experience working with thermal sights
the Syrian scientific research center did before upgrade some of SAA's T-55MV with a Syrian thermal sight for direct engagement.
so the work was on and soon after the Viper thermal sight was born to replace the existing night TPN-3-49 vision sight .
Viper in outer design is similar to TPN-3-49 but with an arch shaped protection ,it also use many of TPN-3-49 components .
Viper range is up to 4km for big objects ,however the useful range for aiming is 1.5-2km tops
the tank gunner aim through an electronic scoop ,however an LCD can be attached .
as firearms flash is more visible in thermal imagery ,Viper is used even in day to detect snipers in urban areas ,giving the Syrian tank crew not only a better vision with less maintenance but also with a chance for revenge ...
