The US-led coalition is to receive new military technology and 450 troops to support its battle against ISIS in Iraq and Syria.
US Air Force major general Peter E. Gersten was quoted as saying that the additional troops will advise and assist Iraqi and Syrian counter-ISIS ground forces in the fight.
The coalition's air campaign saw the addition of B-52 Stratofortress bombers, cyber capabilities and the army's high-mobility artillery rocket system (HIMARS).
The Boeing-built B-52 Stratofortress is a long-range, subsonic, jet-powered strategic bomber that can carry up to 70,000lb of weapons. It can travel more than 8,800 miles without aerial refuelling.
One HIMARS system will be deployed to Turkey to support operations in Syria, while another will support Iraq's counter operations.
HIMARS is the newest member of the multiple-launch rocket system (MLRS) family.
It was developed by Lockheed Martin Missiles and Fire Control under an advanced concept technology demonstration (ACTD) programme in 1996.
Gersten said: "As the general officer responsible for synchronising all combat operations in this theatre, I can assure you that we do everything possible to mitigate the loss of civilian life and minimise collateral damage as we engage this enemy."
