The army in the era of expansion-oriented security strategy:
 dissolution or continuation In the Pahlavi patrimonial system, the imperial army of Iran considered it their duty to blindly obey their superiors without question. For this reason, the army was hierarchically connected to the king and was under his command. Based on the principle of loyalty, the orders and plans of the army were taken from the king and he acted accordingly. Such a system of loyalty was created as a result of the regime's extensive propaganda (reading collective prayers in the morning for the king's health and survival, or the slogan "God, King, Motherland") and, of course, the payment of rewards to the military. The army was completely dependent on the king. The king's autocratic and autocratic culture and relations had made the army so obedient and follower that in the absence of the king, independent and coherent decision and action on its part was completely ruled out. The king was like a country for the army. This degree of loyalty and dedication made the army chiefs not to surrender to the revolution as much as possible, and only declared neutrality when they felt that the revolution was on an irreversible path. Before the victory of the revolution, the leader of the revolution always tried to create a separation between the army and the king. In his messages, he asked the people not to insult the army and not to attack them, and in return he asked the army. Abandon the spirit of dependence on Shah and America and stop killing people. The Imam advised the people to welcome the free and independent soldiers, "The people of Iran are obliged to respect the honorable officers and officials. They should note that a few traitorous army people cannot infect the majority of the army." This peaceful approach of the leader of the revolution played an important role in dissociating the discipline and obedience of the army body to the orders of the superiors and ultimately declaring its neutrality.

The national security of the country prevailed. For this reason, an effort was made to establish a reconciliation between "values" and "realities" and between "beings" and "musts". It is for this reason that some talk about the "cycle of idealism and realism" in the analysis of different stages of the war.
The army and providing national security: defensive operations (September 1959 to May 1960)
During this period, it was decided that instead of a general mutual confrontation with the Iraqi army, the army would limit itself to "local, temporary, local and small attacks".

All the efforts of the army headquarters in the first six months of the war prevented the fall of the cities of Abadan and then Ahvaz. Especially after the fall of Khorramshahr, the protection of Abadan was paid attention to. The army forces succeeded in doing this with the help of the people's forces, and with a few limited operations, they forced the aggressor forces to stop and take a defensive position, which was an important achievement in the way of securing security. and maintaining the territorial integrity of the country was considered.
