The sight is designed for:
– area observations;
– target search and detection;
– target ranging;
– day and night aim firing from KPVT and PKT machine guns.

The sight is applied in BTR-80 APC.
The sight is installed onto the standard site of 1PZ-2 (1PZ-7) sight.

The sight is army accepted in the Republic of Belarus.

The sight is designed to replace the day-time sight PP-61A (AM) applied in turret machine gun mount of the APCs BTR-60, BTR-70 and armored reconnaissance patrol vehicle BRDM-2.

It provides:
– round-the-clock passive detection of targets;
– aimed firing using machine guns in the daytime at a range up to 2000 m, at night at the range of up to 600 m without IR-illuminator.

The sight is installed onto the standard site of the day-time sight PP61A(AM). Replacement of the sight does not require any design modification of the turret.

The sight is army accepted in the Republic of Belarus.

The sight is designed to survey the battlefield around the clock for reconnaissance, detec¬-tion and recognition of stationary and moving targets, aiming and firing from 125 mm D-81 tank cannon and its coaxial machine gun during a daytime and at night, from a halt and on the move.

The sight is installed on tanks when replacing the standard TPN1-49-23 tank night sight and has the ability to interface with a standard tank rangefinder for automatic ballistic correction.

The device is installed onto the commander's turret shaft and does not require any design modifications of standard site of TKN-3.

TKN-N operates in a passive mode and has observation channels:
– day optical channel with magnification of 4x and 8x
– night channel on the basis of an image-converter tube with magnification of 4x;
– thermal vision channel with magnification of 4x.

The device is designed for round-the-clock observation of the terrain while driving a combat vehicle; it replaces standard devices TNPO-170A.
