An early variant of the export-oriented T-90S allegedly saw combat action during the 1999 Chechen invasion of Dagestan instead of being delivered to India. According to "Moscow Defense Brief", one vehicle was hit by seven RPG anti-tank rockets but remained in action. The journal concluded that with regular equipment, the upgraded T-90 seems to be the best protected Russian tank, especially with the implementation of Shtora-1 and Arena defensive systems.
