Sosna-U

The Sosna-U (Russian: Сосна-У, "Pine-U") is a Belarusian/Russian tank gunner's sight used on tanks such as the T-72B3, T-80BVM and T-90MS.^[1][2] It was developed in Belarus by JSC Peleng and later produced in Russia by JSC VOMZ.^[3][4] It features a daylight sight, a thermal sight and a laser rangefinder. The sight contains a built in ballistic computer which takes into account ambient temperature, temperature of the ammunition and current air pressure to calculate the trajectory of the ammunition type selected.^[5]

Sosna-U sight

A major component of the Sosna-U is the Catherine-FC thermal imager which is made by the French company Thales. As Russia seeks to decrease their dependence on foreign companies, a completely indigenous alternative to the Sosna-U has been made, the PNM-T.^[1]
