The upgraded BMP-3 retains the 100mm and 30mm automatic guns and ATGMs, and introduces an improved BZS-1 gunner’s sight, which also feeds images to the commander’s position. The new sight is integrating a SAGEM thermal imager, automatic target tracker and laser rangefinder. Such sight will enable both commander and gunner to search and engage targets. Protection is improved with appliqué armor, and the introduction of active countermeasures such as the Arena E and Shtora-1 defensive system. The powerplant upgrade is also included, utilizing the UTD-32T 660hp diesel engine and new air conditioning system.
