The Islamic Revolutionary Guard Corps (IRGC) is a branch of the military in Iran established after the 1979 Islamic Revolution. Its primary role is to protect the country's Islamic system and maintain the regime's power. The IRGC has its own ground, naval, and air forces, and it operates independently from the regular military. In addition to military duties, the IRGC is involved in various economic activities and has significant influence over Iran's politics. It plays a crucial role in supporting Shia groups in the region, which has led to tensions with other countries, particularly the United States and Israel.
