The Iranian army, the Islamic Revolutionary Guard Corps (IRGC), and the conventional Islamic Republic of Iran Army, have been targeted in US and Israel attacks. The Artesh, which numbers 350,000 and is designed to protect Iran's borders and secure the Iranian homeland, may serve US interests as a force for change when the bombing stops. Mark Cancian, a retired Marine colonel at the Center for Strategic International Studies, warned that if the regular army didn't end up on the target list, it could signal that Trump would leave the force in place to counterbalance the IRGC. Some lawmakers have cautioned against using this strategy, citing Libya as an example of chaos in Iran. The Department of War's warnings indicate the changing target lists across Iran as the US military pounds the country's missile capability and rocket launchers.
