25th Karbala Division

It was first officially formed as the 2nd Karbala Brigade (تیپ 2 کربلا) during the Iran–Iraq War, and was later expanded into a division.

According to Mohsen Rezaei, after a series of unsuccessful Iranian offensive operations in late stages of the Iran–Iraq War, it was decided to form several new brigades in the IRGC, and one new "special" division.

A team consisted of Hossein Basir, Mohammad Hassan Tusi, and other commanders were tasked to organize this division, and Morteza Ghorbani was appointed as its commander.

[2] According to Iranian sources, Iraqi General Maher Abd al-Rashid had described the unit as a "black scorpion" that should be destroyed,[3][4] possibly a reference to their black frogman suits during the battle.

The division was merged with a Basij unit in the Mazandaran Province to form the Mazandaran Karbala Provincial Corps during the rearrangement of the IRGC units in 2008.
