The BNZ program was carried out through government contractor Techinkom out of Saint Petersburg, with the goal of designing a more lightweight alternative to the standard body armor systems, for use by military intelligence and command units. 6B46 sacrifices total coverage of soft body armor, only offering front and back plate protection, however is much more lightweight and modular. It can be configured as a full plate carrier, front carrier only, or chestrig with no ballistic protection.

BNZ is the name of the program, 6B46 is the inventory ID, and "Operator 4" is Techinkom's commercial name.

This example is a new, modernised variant incorporating central opening, velcro for ID on the back panel, and slimline shoulders.
This specimen is in the latest camouflage designed for use in the Syrian conflict.
