Advantage of ERA in early phases of battle! found some footage about the chechen war and at 6:28 you can see a rocket stuck inside the armor of a t72b.. T-72B hit by SPG9... ERA+hit on a thick point of the turret armor=no penetration. vehicle is in good shape despite it is abviously disabled and damaged. Lesson Learned: ERA on T-tanks are important ( Must Have ) other wise its up in air, The tank is clearly saved by ERAs and live for another day to fight.... Compare to M1 Abrams..
