The T-90A is perfectly suited to combat on the modern battlefield. Its three-tier defense system consists of conventional armor, explosive-reactive armor and an electronic jamming system that detects and diverts incoming missiles. Tests of this impressive defense system have concluded that the T-90A is virtually invulnerable to most kinds of ground-to-ground munitions, even at very close ranges. Field reports also show that the T-90A is highly resistant to the threats of urban combat, the traditional downfall of tanks.
