Makhmour Mountains, Iraq -- "Standby. FIRE!"

A deafening explosion followed the commands as a 155mm artillery round exited the tube of an M777A2 during Operation Swift, Iraq, Dec. 22, 2018.

Troopers from the Field Artillery Squadron "Steel," 3rd Cavalry Regiment "Brave Rifles," conducted a gun raid to provide supporting fires for Operation Swift - a series of artillery and airstrikes against ISIS targets in the Makhmour Mountains.

Operation Swift was the first artillery raid conducted in support of Combined Joint Task Force - Operation Inherent Resolve, and demonstrated the Coalition's capability to provide dynamic fires in support of the Iraqi Security Forces.

"Doing the first artillery raid, having never air assaulted a howitzer in theater, was a great experience," said 1st Lt. Aaron Palumbo, platoon leader. "It taught us just how light we could personally pack and helped us identify the feasibility of transporting a Howitzer with rotary-wing assets," said Palumbo.

High explosive charges echoed across Camp Swift night and day as the fire direction center meticulously choreographed the fire missions with airstrikes on multiple ISIS weapons caches and hiding spots throughout the mountains.

"It felt as if we were moving mountains before the mission," said Palumbo. "Now, we have identified friction points and know how to execute future missions with increased lethality."

The barrages of artillery fire were intended to destroy resources of ISIS fighters and send a message that no enemy location was safe from the lethality of the entire coalition force.

"It was interesting being part of the first artillery raid, and doing an artillery mission in combat like we would during home station training," said Spc. Deavon Shafer, ammunition team chief.

During the onset of Operation Swift, Steel troopers both observed coalition aircraft dropping ordnance on known ISIS positions, and reinforced those fires with their own M777A2 howitzer that was air assaulted into position.

The artillery raid was a proof of concept to pass onto future artillery units in theater and a demonstration of the partnership between the ISF and Brave Rifles Troopers in the fight to ensure the enduring defeat of ISIS in Iraq.

When not firing, they trained with the 3rd Federal Police Division soldiers at Camp Swift on the unique weapons systems of both units and conducted artillery training with soldiers of the 12th Brigade, 3rd Iraqi FEDPOL Artillery Battalion.

"The training felt the same as training we do internally - we learned something new," said Spc. Kevin Mahan, M777A2 gunner.

Operation Swift was the first of its kind in theater and will not be the last.

"Task Force Steel executed the artillery raid in conjunction with fixed wing airstrikes to mass joint fires in the Makhmour Mountains and continue the physical and psychological degradation of ISIS," said Maj. Simon Welte, squadron executive officer. "Our operational tempo remains high against ISIS and this raid serves as another example to our ISF and Kurdish Security Force partners that we are committed to the lasting defeat of ISIS in Iraq."

Brave Rifles Troopers are deployed in support of Operation Inherent Resolve, working by, with and through the Iraqi Security Forces and Coalition partners to bring about the lasting defeat of ISIS. Brave Rifles Troopers will eventually be replaced by soldiers from the 1st Brigade Combat Team "Bastogne," 101st Airborne Division, and the Steel Sqdn. has paved the way for future missions.

Bastogne soldiers will continue to provide support to the ISF and deliver massed fires utilizing a variety of firepower to defeat ISIS's combat power and ideology.
