Iran's ground forces command has submitted a proposal to the head of the country's general staff for the upgrade of the armored corps and infantry via the acquisition of advanced Russian T-90 tanks, attack helicopters, ammunition and personal equipment. The announcement was made on the sidelines of a defense conference in North Khorasan by Ahmad Reza Pourdastan, commander of the ground forces. "Currently, T-72 tanks are the backbone of our armor. These armored vehicles have proved to be fairly good in combat operations," he said. "At the same time, we see that the T-90 tank possesses better combat characteristics and meets all the requirements we set," he added. The Iranian news agency that quoted the senior military source did not specify the amount of tanks that Tehran will receive or the date when the deal will be completed.
