The Pentagon is kicking former President Barack Obama’s preferred nomenclature for the so-called Islamic State to the curb.

While the Obama administration often used ISIL, or the Islamic State of Iraq and the Levant, to describe the terror group, a new memo from the Pentagon’s executive secretary says the department needs to start using ISIS.

“The Department of Defense will use the term Islamic State of Iraq and Syria, or ISIS, when referring to this threat,” wrote Executive Secretary Michael Bruhn, in a memo dated Feb. 13. The change was first reported by US News & World Report.
