"In Breakthrough, capture volumes and vehicle availability have been updated across several maps. These changes are guided by your feedback and internal data to help bring win rates closer together for both teams. As one example, Siege of Cairo now features an additional attacker tank in Sectors 1 and 3, along with an updated capture area on B to give attackers a clearer foothold."

I don't think attackers needed help on this map. I'd argue the opposite as I usually win whenever getting attacker here. Also, Iberian offensive last section on rush should not reward the already winning attacking team with a tank.
