I doubt Iran will do anything to target the Cheonghae unit because I think it would lead to broad international condemnation and likely an increased military response from the ROK:
Korea is facing a diplomatic challenge in convincing Iran that the Cheonghae Unit’s expanded mission closer to the Strait of Hormuz is not an intervention in the ongoing U.S.-Iran war, as the Middle Eastern country warned Korea could be “portrayed as an accomplice” of U.S. military attacks.
Although Korea’s defense authorities reiterated that the unit’s expanded duties do not cover the strait but rather are aimed at protecting Korean vessels from piracy, experts say it seems Seoul’s message has not been delivered as intended. This raises concerns that Iran could view the move as entry into the war and lead to potential clashes.
