Naval Brigade 13 Amir al-Momenin was one of the IRGC units stationed in Bushehr that participated in the Sacred Defense.

Following the beginning of the Imposed War of Iraq against Iran, the people of Bushehr Province also participated in defending the country. Early in the war, a number of Bushehr combatants participated in Samen al-Aemmeh (PBUH), Tariq al-Quds and Fath al-Mobin operations in the Al-Mahdi (AJ) Brigade and 19th Fajr Division of Fars Province.
