"As with any military operation supporting another force, coordination and synchronization of effort is essential. To that end, a small number of U.S. forces have gone in and out of Libya to exchange information with these local forces in established joint operations centers, and they will continue to do so as we strengthen the fight against [ISIS] and other terrorist organizations," said Deputy Defense press secretary Gordon Trowbridge. Those forces are based in joint operations rooms, away from the forward line, to facilitate coordination among Libyan forces fighting ISIS, he said. The Pentagon announced on Aug. 1 that it had expanded its air war against ISIS into Libya, where its fighters have established a foothold in Sirte.
At the time, defense officials said there were no U.S. forces on the ground supporting the air operations, but did not deny there were U.S. forces on the ground there.
