Not only that, their ammunition was also janky, the best tank round the Iraqis have at the time was the 3BM15, which can only penetrate 135-150mm of at 60° from 2km, and 310mm at 0° from the same range, the Abrams however had 400+mm on the front hull and 740+mm on the turret, which meant that the T-72 can only penetrate the Abrams from closer ranges or from the sides or rear, this coupled with the fact that the T-72 lacked the effective range and fire control systems and generally poor tactics made the T-72 a sitting duck, and on top of that the T-72 fell prey to aerial attacks as the Iraqis had no air superiority to challenge the coalition air forces.
This then led to the development of better armor for the T-72, such as the introduction of the Relikt ERA, new ammunition like the 3BM44M, new ballistic computer and thermal imagers for the T-72, and an overhaul in tactics for using the tank
