He personally penetrated the positions of the units of the Iraqi Army's 3rd Corps in order to obtain information about the enemy's situation.

[9][10] Hassan Bagheri had a great talent in analyzing the enemy's information and predicting possible movements of the Iraqi army in the future.

These battles were carried out in a situation where the regular operations of the internal forces had encountered problems and often remained without results.

"Although he was ordered to take complete medical rest for a month, he left the hospital after a week and returned to the southern operation headquarters.

[10][20] During the Operation Ramadan, which began on July 14, 1982, in the Shalamcheh operational area, which is east of the southern Iraqi city of Basra, the forces under Bagheri's command passed through explosive traps and mines, and reached a depth of 27 kilometers into the Iraqi territory and near the city of Basra.

[10] After the successful completion of the Muharram operation, Bagheri was appointed as the deputy commander of the IRGC ground unit.

[23] Also after the impact of the mortar shell, Tawakkul Qalavand (Deputy Intelligence Officer of Najaf Base) and Majid Baqaei were also killed and Morteza Saffari was seriously injured.

[13] According to Mohsen Rezaee, the commander of the IRGC during the war, the success of Iran's armed forces was achieved through the method of experimental development,[25] of which Hassan Bagheri was one of its experts and creators.
