The motto of the U.S. Marine Corps, or USMC, is “Semper Fidelis.” Commonly translated to “always faithful,” the motto—adopted in 1883 upon the urging of Colonel Charles McCawley, 8^th commandant of the Marine Corps—replaced earlier mottos, including “with courage” and “by sea, by land.”

The definition of the motto and what it “means” to be a Marine is different for different people, and almost never exactly what one probably thinks from the outside looking in. Now commonly shortened to “Semper Fi” by Marines, the motto and its history bear testament to the essentially arbitrary way in which rules are enforced not only in and by the USMC, but by and in American society, as well. After all, “Semper Fi” means “always fi,” in Latin—fi means nothing, it’s a nonsensical term. Taken at face value, the reduction of a motto to shorthand underlines the motto’s essential mutability. Faithful… to what? Each other, the constitution, the president? Always… since 1883?

Meaning, as every adult understands, is highly contextual. This essential truth underlines most modernist and all post-modernist art and literature. When one takes the changeable truth of life and runs it through a harsh and dogmatic set of ideals, the resulting psychical energy is sufficiently powerful to drive some people to superhuman acts of discipline, in the name of honor and self-respect, and this is very useful when fighting a dedicated enemy. It drives almost everyone else mad, according to the extent to which they failed to live up to those ideals. Some rationalize their misbehavior, building up elaborate personal philosophies to justify their actions. Others descend into pessimism and become jaded.

Teresa Fazio is a proud former Marine, and her war memoir—Fidelis—grapples with that mutability at the heart of everyday life, and her own efforts to live up to ideals. It is a top rate book about war, and how serving in the Marines requires great reservoirs of emotional energy under normal circumstances, but especially on deployment to Iraq. It will resonate with anyone who has served in the military. Fidelis may even give military leaders something to think about when it comes to setting and enforcing rules.

The story begins with Fazio’s difficult family background—a household broken by infidelity, and an abusive stepfather, the type of situation that breaks many people down and ruins their potential before they have a chance to properly begin their lives. The setting did not break Fazio. Instead, she discovered great reservoirs of personal forbearance that complemented an aptitude for science. She put herself through MIT on a Marine Corps ROTC scholarship. She also learned early to rely on herself to succeed and overcome obstacles in an effort to achieve independence in two worlds dominated by men, first, that of science, then, that of the military.

One of the threads that Fazio follows from her childhood through the military and then afterwards is her complicated relationship with femininity. Growing up, she seems to see in her mother’s adultery a kind of moral hazard specific to women, and this feeling is reinforced by the masculine circles in which she moves. It takes time and great effort for Fazio to overcome this inherent bias against her own identity as a woman, both in her own estimation and from others. The parts of her memoir that deal with this question are unsparingly honest.

Once in the military, Fazio proves herself a competent leader whose attention to detail makes her ideally suited to ensuring that communications for a Battalion-sized fort ran smoothly. The war intrudes in the form of dead bodies from outside the wire, and also mortar attacks, one of which nearly ends her life. Nevertheless, Fazio’s greatest challenge arrives in the form of a man—a much older, and (not incidentally) married man, who seduces her in Iraq, and with whom she sleeps after the deployment. Far more troubling to Fazio than the embarrassment of having fallen for a manipulative adulterer is her violation of two codes: her personal code, which depended on a lifelong repudiation of using femininity to gain any advantage (in this case, the attention of a man), and her violation of her expectations of herself as an officer and a Marine.

Above all, Fidelis is a memoir of endurance; a story about how a person can bear up under the weight of external and internal expectations. The prose is spare and straightforward, assembled carefully, attentively, and in a way that drives the reader forward sentence by sentence, paragraph by paragraph, chapter by chapter all the way to the end. Capable of being experienced in a weekend, or even over the course of a single day, at 215 pages, Fidelis is, like Fazio’s deployment, intense.

The story is also filled with moments of understated wit, such as when she describes the midnight runs necessitated by a shift schedule that required her to stay awake at night:

Before midnight, I ran on the rough gravel roads, carrying a flashlight so trucks could spot me. Even with its bouncing beam, I could hardly see five feet ahead, and I tripped over concrete chunks, bruising my knees through OCS-issued sweats. I got up and kept running. Head- lights higher than my head screamed toward me, and I scrambled off-road to avoid them. Trucks roared past, carrying water or sewage to or away from this place; I couldn’t tell. I turned around and jogged back for a freezing shower.

Of a rebound relationship, “if I squinted, it looked like love.” Of the internet and cell phones, technology made it easier to talk, but not to connect.”

According to Fazio, and the strict rules of the Corps, in helping a married man cheat, Fazio failed to live up to its standards of behavior. But she was surrounded by people who were skirting the system—drinking on deployment, cutting corners, focused on their own happiness and well-being first, before that of the corps. Not, in other words, being Semper Fidelis.

This is one of Fazio’s greatest accomplishments: she remains essentially optimistic, loyal to the Corps and to her memory of the military. In spite of the failure of various Marines to live up to the ideals of the Corps, in spite of her own inability to reach perfection, Fazio carries out her assigned duties faithfully. Making an error, even one that consumes a substantial portion of one’s energy and attention, does not define an individual, and although Fazio’s error was apparent to her at the time and since, this aspect of her life does not capture her essence any more than it captures the essence of any human. The experience could easily have ruined her as an officer and a human, embittering her and turning her toward cynicism — but she must have been a competent and caring officer, and earning a PhD at Columbia after leaving the military establishes her bona fides as an intelligent and steadfast worker.

In writing Fidelis, Fazio more than makes up for her in retrospect understandable transgressions, by offering aspiring young men and women a realistic and expertly-written account of what it’s like to go to war. Her unprepossessing prose, dry humor, and faithful rendition of the trials and temptations faced by deploying women should be read by anyone curious about what it was like to be a woman in the Marine Corps.

The following excerpt is from Teresa Fazio’s Fidelis: A Memoir, reprinted with permission from Potomac Books. 

A week before leaving Iraq, I shuffled through my post-deployment health assessment, a quiz to divine if we were crazy or sick or prone to shooting our loved ones. I gave the pasty Navy doc the answers he wanted: Yeah, I’m fine. No, I haven’t seen anyone killed—lifting that transport case doesn’t count. Yes, of course I was exposed to sand. No, no nightmares, not lately. Shit blows up, whatever. No anxiety, just stress. I’m an officer; I can handle it. Let me go.

I was impatient with anyone who hadn’t also been in Iraq for seven months, laying cable like my wire platoon. Our replacements’ questions—where did this cable lead, when was chow, was there really a shot-up mural of Saddam Hussein—disrupted my precious workaholic routine, the one for which Marla, another female lieutenant, had nicknamed me Rain Man. With the new troops swelling our numbers, we spent the next several weeks laying as much cable as possible. The Marines bore down, digging what trenches they could with a motorized Ditch Witch, then pickaxing the more sensitive areas bordered by concertina wire. They laid cables straight into sandy trenches, zip-tying them every few feet and burying them under fine grains. Their knees shone white, and they washed grit from their hands and necks before meals. It sucked, but it was celebratory for the Marines leaving country: a last hurrah, the old guys willing to do anything to get out of there, the new guys excited to do anything at all. Even if it meant pulling cable hand over hand, fingers pruning with sweat in canvas gloves. As they tipped blue strands of Ethernet, bits of plastic tumbled to the ground, until everything was wired in. I watched Marla help dig, her slim figure bent at the waist, forearms dirty, red bun over delicate features. Though half the company comprised new troops, I didn’t overhear anyone hit on her.

Fortunately, a squared-away comm-school classmate named Torres took over my wire platoon. Major Davis tossed me the keys to our battalion’s SUV, so Torres and I could inspect the cable line. Airfield to the left, headquarters to the right, the rest of Camp Taqaddum a desert plateau. The Euphrates winked below us if we craned our necks just right. Though I hadn’t driven in seven months, the potholed roads felt familiar. Torres’ clean uniform stood out against dusty upholstery.

I pulled over within sight of some junked Soviet planes, where I’d once gone on a long run with Jack and one of his sergeants.

Torres asked if mortars hit around TQ a lot. I told him that in the past month, most of the danger had stayed outside the wire. Except down that road—I pointed toward the gate where insurgents had crashed a vehicle full of explosives. And, I continued, when the mortars got close to regiment, peppered that empty tent—that was bad. Cut our fiber optics. Fucked up like a football bat. I climbed out of the car and kicked a toe in the sand, unearthing zombie cable. Torres didn’t ask any more questions.

A few afternoons later, hopped up on caffeine with nothing to do, I called Jack from the Systems Control hut. He couldn’t hang out; he had an angel coming in, he said, a mortar victim from Fallujah. All of the other times I’d been in his room, he’d shooed me away when the calls had come. This time, I asked to watch him work. I wanted to finally witness the cause of his sleepless nights.

“Major Davis would crucify me if I let you see this without him knowing,” Jack said. But when I asked the major if I could watch Jack work, he just braced a hand on the two-by-four door frame and said, “Yup.”

In his bunker, Jack pressed play on James Taylor’s Greatest Hits. It calmed him, he said. Two Marines lay a stretcher on sawhorses and unzipped a body bag: an ashen Navy Seabee with a fresh haircut. Blood sluiced to the sawdusted floor. One Marine held the clipboard; several more circled the body. They marked the locations of wounds and tattoos, crossing the Seabee’s stiff arms over his chest for balance. Jack donned nitrile gloves and pulled a brand-new pack of Camels from the Seabee’s pocket. A fist-sized hole bled where a heart had once beaten. Fire and Rain kept time.

I shifted from foot to foot as Jack counted dog tags, ID card, wallet, and photographs into a manila envelope. He motioned me back with an outstretched arm and a frown.

The whole process took only fifteen minutes. Soon the chaplain thumbed a cross on the Seabee’s brow. The Marines put him in a fresh body bag, strapped it into a flag-draped transport case, and tied it tight with twine.

After, Jack wadded his nitrile gloves into the trash and led me to his room. We shut the door, no matter his Marines cleaning up in the outer bay. He pulled me in, kneading my back; I pressed my nose into his T-shirt and inhaled. Together, we breathed.

The next night, there were no casualties. I stayed long enough after midnight to hear Jack say my name and “I love it when you touch me” and his son’s name and “I love you.” He saw the dead when he slept. He thought of them constantly, he said, except when he was with me. We dozed an hour. Then I pressed my lips to his forehead, found my glasses, and slipped away. Six more days left in Iraq.

The next morning, on my walk to stand watch, I ran into Sanchez exiting the chow hall. I teased him about the samurai pads snapped to his flak vest: floppy hip guards, shoulder pads, a flat, triangular groin protector. Each piece sported a different pattern: digital desert, analog woodlands, Desert Storm chocolate chips. He was a Marine Corps fashion nightmare.

When I got to work, I found out the reason for all that gear. A vehicle-borne IED had hit a convoy northwest of Fallujah, killing seven Marines and wounding six. A “mass casualty” event. Jack, Sanchez, and others rode out on a convoy to recover the bodies.

I couldn’t sit still, so I walked into the TechCon van. Maybe the sergeants could offer distraction, whether with work, or with Nip/Tuck, their latest binge-watching addiction featuring plastic surgeons in compromising relationships. We watched for three hours, until we hit an episode where the plot revolved around infidelity.

I remembered that Jack was on the convoy.

This “other woman” had terminal cancer. Her adulterous lover helped her commit suicide before the cancer took her. The woman penned letters and sipped milk to coat her stomach while swallowing handfuls of pills. As she watched a lakeside sunset and the soundtrack played Elton John’s Rocketman, I felt a wash of fear.

Jack was still on a convoy.

While watching the show, I wondered, Will that be my punishment, too? I’d become increasingly anxious about our imminent return to the States. Even more than getting caught, I feared losing what I thought was my only chance at love. Jack’s wife in California loomed far larger than any bomb threat. A thick sludge of guilt coated my powdered-egg breakfast. I controlled my breathing.

He was still on a convoy.

After the episode ended, I stumbled out of TechCon into sunlight, blinking back lethargy from hours of TV. I had to do something good, something officer-like: inspect the cable. Check on my troops. I controlled my breathing and swallowed the lump in my throat.

At the far end of the flight line, my Marines were deepening a trench in a spot plagued by heavy truck traffic. I walked the fiber optic lines along the airfield’s edge, checking them for bald spots, kinks, and cuts. The air reeked of diesel. Helicopter rotor blades blended into a buttery hum. Sparrows flitted along eight-foot-tall Hesco barriers. After fifty yards or so, I stopped and peered down the flight line. Maybe a hundred yards left. Hot, boring work. I figured I could get to my Marines more quickly on the other side of the barriers, where there was a concrete path. I ducked behind them at the next opportunity.

• • •

WHUMP. Seconds later, a mortar landed on the airfield. I felt the blast wave in my chest and teeth. I took a few steps forward, thinking of my troops digging near the flight line entrance.

WHUMP. Another mortar round, a little farther away. A small rock kicked up by the blast flew over my head, or was it shrapnel? I had the urge to reach for it, to catch it, but I did not. Instead I turned around to head back to our company’s headquarters. As my Marines fast-walked past me, carrying ammo cans full of tools, I thought only of counting their heads.

In the following months and years, I would wish I had been on the exposed airfield side of the Hesco barriers when the mortars hit, that I had sprinted full-tilt toward my Marines digging that trench, instead of taking a few steps forward before retreating. I would even wish I’d been hit by shrapnel, like a vigilant lieutenant. Was that the most fitting consequence of what I’d been doing with Jack? If he returned from his convoy to find me lifeless, would caring for my body have made him love me, made him stay?

In any case, he returned. Late that night, I lingered outside Comm Company’s compound under a hard pearl moon. A hundred yards away, Jack’s Marines unloaded one, two, three, four, five, six, seven body bags from their refrigerated truck. Then they hefted still more.

Under the floodlights, I made out Hoss’s lanky silhouette, spotted Mullins’s round shoulders and rolling gait, almost heard his Southern drawl. Two more darted around the truck, its tailgate the height of their heads, shepherding paperwork. Sanchez stood straight and musclebound, lifting tirelessly. Sergeant Jonas barked orders.

Soon they all moved inside; they must have been grabbing clipboards and unzipping body bags. I stared at the bunker doors, wishing I could enter. If I had tried, Jack would have shouted me away, and Mullins and Jonas would have shaken their heads. I would like to say decorum held me back from going over there. Really, it was shame. The most honorable thing I could do was stay away. Wait to go home.
