TAQADDUM, Iraq — The war here smells like diesel fumes and nostalgia.

In the distance, there is an explosion, a single thud that has the Marines of Baker Company, 1st Battalion, 7th Marines, on their radios trying to figure out what it was. “Iraqi artillery, I think,” the Marine sitting in a reinforced observation point, known as Post Eight, decides. It is dark and getting cold, and the Marine on Post Eight, an infantryman, has been here since October.

Post Eight and its fellow line of fortifications is just adjacent to Taqaddum’s tarmac and makes up one of the borders of the American camp — called Camp Manion, after a Marine lieutenant who was killed by a sniper in Iraq in 2007. The camp is an outpost within an outpost — an island in the middle of the now Iraqi-controlled Taqaddum airbase where a small contingent of Marines, soldiers and Special Forces help train Iraqi troops to fight the Islamic State in this new chapter of the Forever War.

While some of the fortifications around the American part of the base are holdovers from years past, most of them are new and have been flown in and constructed in the last year. When the Iraq war ended in 2011, the United States tore down almost all of its old bases in the country. Now, four years later, it is rebuilding them.

“No one is better at kicking our own ass than ourselves,” one Marine quipped.

Less than a decade ago, at the height the conflict’s last iteration here, Taqaddum’s mess hall was renowned across Anbar province. A five-star dining facility tucked between the restive cities of Fallujah and Ramadi, Taqaddum had a spinning glass case of self-serve desserts that has since become an object of legend — whispered about wherever Americans find themselves at war.

But now it is no more, erased since the last troops pulled out in 2011. The current mess hall is a shell of its former self — a drafty warehouse with walls covered in a patchwork of tarps and a dessert selection relegated to cardboard boxes filled with Pop-Tarts.

Just a few hundred yards away from Taqaddum’s now-rudimentary dining facility is the wooden command post for Baker Company. Inside, among many things needed to run an infantry company effectively, is a plastic Christmas tree bought from Home Depot and a cache of socks sent from the Socks for Heroes organization.

The Christmas tree is a new addition to the company. Covered in tinsel and ornaments and lights, the tree could be lit, but the Marines have decided that the one power adapter they have should remain attached to their coffee machine. Their first sergeant, however, whose parents sent the tree and its accompanying decorations, has plans to light the tree on Christmas.

“It’ll be like kind of a ceremony,” he said, and the sergeant who leads the company’s engineer detachment has assured him it will work.

Baker Company is tasked with security for all of Taqaddum, and the Marines take turns rotating between patrolling inside the perimeter, standing post and manning the quick reaction force, or QRF. The QRF stays in a room next to the operations center for 24 hours at a time. There, they eat and sleep and wait for something to happen. Often, nothing does, but recently Marines from Baker Company and their accompanying medical personnel, known as Navy corpsmen, have responded to Iraqi casualties brought to Taqaddum’s entry control point. The majority of the casualties, according to Marines from Baker Company, have come from the Iraqi military’s ongoing battle to retake the key city of Ramadi.

Aside from the war, and the Iraqi casualties and their new Christmas tree, the pressing issue for Baker Company is the new Star Wars movie, which many would like to see soon. With the Internet now readily available in the Forever War, there is little hope among Baker Company’s Marines that they can make it until the end of their deployment without inadvertently stumbling on a spoiler.

But one Marine — who knows a guy, who knows a guy — thought he might be able to get his hands on a bootleg from the Iraqis (as the Iraqis have been known to bootleg such things). The effort is a long shot but now urgent since the Marines heard that one of their fellow companies, Weapons Company — stationed approximately a hundred miles to the northwest at Asad air base — had secured a screening.

“If we watch it we could make costumes,” one Marine from Baker Company said. “You know, we could turn Hesco cloth into Jedi robes.”

Weapons Company from 1st Battalion, 7th Marines, of Twentynine Palms, Calif., indeed plans strong attendance at Asad’s multiple screenings of “The Force Awakens” on Dec. 28. The group carries out many of the same tasks as Baker Company, but it is stationed at Camp Havoc, another “base within a base” where its Marines patrol the perimeter of Asad’s airfield and provide security as Danish troops help train elements of the Iraqi army’s 7th Division.

Aside from Marines acting as base security, other units from the 7th Marines stationed elsewhere in the region provide detachments specifically dedicated to recovering downed aircraft and crew members. Marines are also assigned to a broader task force to assist Iraqi offensive operations by sharing intelligence with their Iraqi counterparts, as well as helping with indirect fire from Camp Havoc’s 155mm self-propelled howitzers and GPS-guided rockets, also known as High Mobility Artillery Rocket System or HIMARS.

“What’s tough for Marines to wrap their head around,” one Marine said, “is that this time around we don’t own [the battlefield]. We only influence it.”​
