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.
