Grunt: The Curious Science of Humans at War Read online

  Fallon turns the class over to ArmorCorps’ Craig Blasingame, a former Marine with a wide superhero jaw and muscles so big that when he walks in front of the slide projector, entire images can be viewed on his forearm. Though it’s ten in the morning, Craig has a five o’clock shadow.

  “We’re going to put you in an environment today and show you what it’s like to try to maintain a degree of auditory situational awareness while you’re wearing passive hearing protection.” Craig speaks like a bullhorn. He says this is because he lost some hearing as a Marine, but I think it’s because there’s so much strength coursing around in there that everything—whiskers, voice, the pectorals under his polo shirt—wants to burst forth in a powerful way.

  Craig and Aaron Iwanciw, also a former Marine and now CEO of ArmorCorps, will shortly be taking the audiologists (and myself) outside for a listening exercise. Because we’re going to the firing range afterward, this is one of the rare listening exercises that will be done in body armor and a combat helmet. Aaron is smaller and quieter than Craig, and smells pleasantly of shampoo. He helped me put on my gear. (“I can stick my lip balm and tape recorder in these little skinny vest pockets.” “Those are for ammo.”)

  Outside the building, Craig arranges us in a patrol formation. In a war zone, just walking down the road has a strategy to it. The “killing radius” of a fragmentation grenade is 15 feet. If troops walked along in a clump like tourists, a single grenade could kill the lot of them. Thus they keep fifteen to forty-five feet between each other on patrols. The more spread out they are, though, the harder it is to hear one another, especially with hearing protection in place.

  Aaron is the point man, while Craig takes up the rear. We’re wearing ear cuffs similar to the ones people wear when they operate power tools. Craig sounds like someone shrank him down and put him inside a mason jar. I believe I hear him tell us to “step off right.” I interpret this as meaning we’re all supposed to clear off onto the right side of the road, so I start crossing over. “You’re on the left,” barks a teammate. He sounds sure, so I turn back and narrowly avoid being hit by a black Suburban creeping along seemingly out of nowhere. When a two-ton SUV driving on gravel can sneak up on you, that’s not good.

  Fallon says lapses in communication were the norm when he was in the infantry. “Do you know how much time I spent saying, ‘I have no idea what’s going on’? We’d get an order to halt, spread out, take up a more hidden position. My buddy next to me would be going, ‘What’s going on?’ And I’m going, ‘Shit, I don’t know what’s going on.’” And you couldn’t yell, ‘Hey, what’s going on?’ because the enemy would hear you and know where you were.

  Aaron is leading the next exercise, a live-ammo “tactical scenario” out in the wilderness beyond the firing range. Before we head over, he has us push a button on the ear cuffs we’re wearing. This is the point in my notes where it says, “bionic!” As a kid, I used to watch a TV show called The Bionic Woman. Like her male counterpart of an earlier season, she’d been rebuilt by the military with experimental superprosthetics following some variety of hideous maiming. It was the least they could do. One of the implants was for her ear. She’d cock her head, and suddenly we’d be eavesdropping on a pair of underworld kingpins in a Buick Riviera across the street. I have her hearing now. Aaron is fifteen feet away, talking to Craig, but he sounds so close I should be smelling shampoo.

  The name for what we’ve got on is TCAPS (say, tea-caps), Tactical Communication and Protective System. Incoming noises are analyzed; the quiet ones are amplified and the loud ones reproduced more quietly. (The system also incorporates radio communications, or “comms.”) So far it’s mainly Special Operations forces who are using TCAPS. Why? Money, of course, but also the fact that it comes out of the radio budget, and the majority of foot soldiers don’t carry radios. Plus some skepticism among leadership. “Senior NCOs,” says Fallon, referring to noncommissioned officers, “will flat-out tell you, ‘Don’t give me more shit that’s supposed to be the next high-tech wonder that’s going to break or the batteries are going to go dead and I’ve got to carry it.’”

  The shit we have on happens to be made by Fallon’s employer, 3M. “I hope you don’t think that that’s what this is about,” he said to me at one point. I don’t, entirely, no. Fallon is an evangelist for the product category, not the brand. 3M also supplies earplugs to the military, so either way, they’ve got a tasty piece of defense budget pie.

  The hearing professionals and myself are joined for the tactical exercise by twelve men from a Marine Corps Special Operations unit, the name of which I’ve been asked to omit. Aaron briefs the lot of us.

  “You are a Special Operations team heading into a village in Afghanistan,” he begins. “The mission is to make a liaison with the village elders. Engage the elders, ask about Taliban activity in the area. Ask them about their quality of life. What their problems are.” Perhaps fit them for hearing aids. “In support of the operation, we have a Predator drone in the overhead, and quick access to an assault weapons team: Cobras or Hueys. If things go kinetic we can call them up for supporting fire.” Going kinetic is military shorthand for people are firing guns at you. In this case, they’re imaginary people, but the Spec Ops guys will be shooting back anyway, because this is an exercise about communicating in the chaos and clamor of combat.

  We’re instructed to turn our radios to channel 7 and line up behind one of the Special Ops guys, two of us per guy, as close as possible without hitting his boot heels. “If he runs, you run,” says Aaron. “If he takes a knee, you take a knee.” Myself and a middle-aged audiologist with braids poking down from her helmet get behind a short man who is hard to describe because all distinguishing features except his nose are obscured by gear of some kind. He introduces himself and says hi.

  “Hi, I’m Mary,” says the audiologist.

  Me too, I say. “I’m also Mary.”

  “Well,” says our Special Ops guy, clearly unaccustomed to so much Mary. “That does make it easy for me.”

  We set off into the scrub. Camp Pendleton is two hundred square miles, with seventeen miles of California coastline, much of it left wild for practice invasions and amphibious assaults. It’s like a national park reserved for the U.S. Marine Corps and a lot of twitchy wildlife. (The grunts are forbidden to shoot the animals, but I’m guessing it happens. I’m guessing this because I recently visited the Camp Pendleton paintball range and asked to be shot to see what it feels like. Fifteen Marines volunteered. The one who did the deed—from 70 feet, hitting me precisely where he wanted to—can be heard in the background of a researcher’s video going, “That was very satisfying.”)†

  As we make our way across the terrain, a multiparty conversation unfolds in my ear cuffs. One man is talking with the drone operator, and someone else is communicating with the Cobra pilot and the attack controller. Everyone, including the President of the United States, if he wished to, can switch their comms to channel 7 and listen in. (When Navy SEALs stormed Osama bin Laden’s compound, they were wearing TCAPS, and President Obama and Secretary of State Hillary Clinton were listening in.)

  I don’t know how often our guy has his talk button pressed and how far my voice behind him carries, but it’s possible that the transcript of this mission would be somewhat irregular:

  “Approaching village, over.”

  “Copy, Liberty. Any update from the target site?”

  “You need to put some sunscreen on the back of your neck.”

  “This is Hammer in the overhead. We have four military-age‡ males who appear to be orienting themselves to the objective area.”

  “Copy that, Hammer.”

  “So do the Taliban use hearing protection?”

  “This is Hammer. We’ve got an exodus of women and children from the village. Two other military-age males messing with something under a tarp.”

  “Start surging assets.”

  “Halo, you are approved for rockets and guns, over.”
<
br />   “All these holes in the ground—are they from mortars or, like—”

  “Prepare to attack!”

  “—gophers?”

  “Attack imminent!”

  Simulated kinetics ensues. With Mary right behind me, I scramble to stay as close to our guy’s back as possible without rear-ending him when he stops to shoot. I try to picture what the group of us must look like, but my brain can’t decide between Zero Dark Thirty and the Bunny Hop. I imagine officers walking back from lunch, one nudging the other: “What’s going on out there?”

  “Audiologists.”

  The mission ends back by the classroom. We turn in our gear and head inside for a Q&A session with the Special Operations men. They sit in mismatched office chairs in a row at the front of the room. “How many of you,” the first question goes, “have hearing loss?” All twelve raise a hand. By one (pre-TCAPS) study, Special Operators, as they are called, had the highest rates of hearing loss in the Army. Both in training and on the job, they spend a greater than average amount of time around explosives and large, noisy artillery. Unless they’re snipers. They’re either very loud or very quiet, these men.

  “I don’t understand,” says a voice from the back row. “As an audiologist, I never have people come in to my clinic going, ‘Oh, my god, I can’t hear! I had an incident, and now my hearing is diminished.’”

  Chair number 8 explains: “Guys want to go back in and do the job.” If a hearing test turns up a loss in excess of a prescribed amount, it can mean being declared unfit for duty or having to secure a waiver to get around it. These are men who, by and large, love what they do. They avoid audiologists for the same reason they avoid doctors.

  “I don’t want to stop doing what I’m doing,” agrees chair 3. “When I take those tests. . . . How can I say this? I want to pass. So I’m like, ‘Okay, I think I hear a tone.’” Cheater!

  Also? This is Special Operations. Oh, my god, I can’t hear! is not in the script. When things go kinetic, there’s a greater than 50 percent chance that a member of the team will be injured or killed. Hearing loss isn’t something they spend time worrying about. It’s a given. “You expect,” adds chair 2, “that you’re going to take some kind of degraded hearing on separation.” Fallon told us that as an artilleryman, he wanted a hearing loss, because everyone in his unit had a hearing loss. “If you didn’t have a hearing loss, that meant you hadn’t done anything.” It might also mean you were born with a robust medialolivocochlear (MO) reflex, which directs the brain to lower the volume on egregiously loud sounds. Nature’s TCAPS. Naval Submarine Medical Research Laboratory researcher Lynne Marshall, who is here today, has been working to develop a simple test to identify people with weak MO reflexes so they can be given extra protection.

  Chair 6 chimes in: “They’re pushing TCAPS for, like, Hey, protect your ears. But for us the main function is the comms. The situational awareness.” According to a Hearing Center of Excellence fact sheet, 50 to 60 percent of one’s situational awareness comes from hearing.

  Fallon calls for one last question before we leave for dinner. Again, it comes from the back row. It’s almost more of a plea: “Has an audiologist ever done anything positive for any of you?”

  “Yes,” volunteers chair 5, a dark-haired, dark-eyed, just generally dark sort who hasn’t said much until now. “They fitted me for my hearing aids.”

  Whomp, wha? Virile, omnipotent Special Ops man wears hearing aids? My reaction is the same mildly stunned one I had upon reading that Angelina Jolie had had her breasts removed. The man went on to question the policy of declaring someone like him unfit for duty. “We let people have devices for corrective vision. Well, I have a device that helps my hearing.” What’s the difference? It occurs to me that the US Special Operations Command may succeed at something perhaps more challenging than killing Osama bin Laden: erasing the stigma of hearing aids.

  IT IS an interesting fact that retired four-star general David Petraeus was shot in the chest on a firing range but not, at the moment, a comforting one. Not that it’s Craig Blasingame’s job to be comforting. His job here at the Camp Pendleton firing range, and he’s doing it nicely, is to knock out of us any complacence that might be lingering after the run-through of the nearest helicopter medevac points and what to do if searing hot bullet fragments fly down the back of our shirt while we’re firing our semiautomatic M16A4 assault rifle. (“Just say, ‘Hey, I got some brass.’”)

  The Special Ops guys will be serving as our shooting tutors. We’ll be firing two magazines of ammo each, one with earplugs, one with TCAPS. Ostensibly, this is to demonstrate how hard it is to hear commands while shooting with passive hearing protection in place. It was also, I’m guessing, audiologist bait: Come shoot M16s with the men of Special Operations! (Worked on me.)

  Craig splits us into two groups, half on the firing line and the rest, including me, a few yards back in the ready box. “Now if this isn’t for you,” Craig is saying, “if you start to freak out, you can put your weapon down, put your hand up, and say, ‘This isn’t for me.’” If only war were like that.

  To get an earplug far enough in to do its job, the pinna—part of the outer ear—must be pulled out and back, an impossible task while wearing a combat helmet. No one, in the heat of a firefight, is going to pause to take off her helmet, pull back her ear, insert the plug, and repeat the whole process on the other side, and then restrap the helmet. There’s time for this on a firing range, and there might have been time on a Civil War battlefield, where soldiers got into formation before the call to charge. Back then, or out here, you knew when the mayhem was about to start, and you had time to prepare, whether that meant affixing bayonets or messing with foamies.

  There’s no linear battlefield any more. The front line is everywhere. IEDs go off and things go kinetic with no warning. To protect your hearing using earplugs, you’d have to leave them in for entire thirteen-hour patrols where, 95 percent of the time, nothing loud is happening. No one does that. That’s why Fallon says, “The military doesn’t have a noise problem. It has a quiet problem.”

  “Group 2,” yells Craig. That’s me. “Advance to the firing line!”

  “Hey, how are you?” says my instructor. “My name’s Jack.” Jack is unlike the Special Ops guys I have met elsewhere. He’s friendly as a Labrador retriever, clean-shaven as a regional sales manager. Perhaps he’s carrying out covert ops in San Diego or Scottsdale and, like the bearded Special Operators in al-Qaeda country, needs to blend in with the local male populace. Perhaps he’s between missions.

  Jack points to my helmet. “Those straps need to go over your ear cuffs. Now that’s going to make your helmet tighter, so you probably need to loosen them a little bit.” One of the problems with over-the-ear TCAPS is not the equipment per se but the order in which gear is distributed. Helmet fittings used to happen before TCAPS gear was handed out. Guys would try to put their helmet on with the TCAPS headset and now it would be too tight. This seemingly minor planning boner has cost a lot of men a lot of hearing. The one time an IED exploded near Jack, he wasn’t wearing his TCAPS. “It was hot, and they were giving me a headache, so I opted not to wear them on that one patrol. And that was the one I got blown up on and had significant hearing loss. Aaron had the same thing.”

  To my right, an extremely lethal hearing professional has already emptied his first magazine. I’m still battling my helmet straps. “Let me help you,” Jack says. I drop my hands to my lap and let him take over. “Oops, I don’t want to pull your hair.” The gentle sniper.

  Jack passes me the M16. “Have you shot a gun like this before?” I shake my very heavy head. He hands me a magazine and shows me where to load it. I’ve seen this in movies—the quick slap with the heel of the hand.

  Hmm.

  “Other way. So the bullets are facing forward.”

  The M16 has a scope with a small red arrow in the center of the sight. You align the arrow with what or (jeez) whom you wish to shoot and squeeze the
trigger. Both “squeeze” and “pull” are exaggerations of the motion applied to this trigger. It’s a trivial, tiny movement, the twitch of a dreaming child. So quick and so effortless is it that it’s hard for me to associate it with any but the most inconsequential of acts. Flipping a page. Typing an M. Scratching an itch. Ending a life wants a little more muscle.

  The crack of an M16 is around 160 decibels. Jack estimates he’s fired a hundred thousand rounds in his ten-plus years in Special Operations. Weapons and explosions, rather than ongoing “steady-state” noise from vehicle engines and rotors (and MP3 players),§ are the biggest contributors to the $1 billion a year the Veterans Administration spends on hearing loss and tinnitus.

  Most of those hundred thousand rounds may not even have registered, not because Jack had hearing protection on but because his attention was elsewhere. “When you get in a gun fight and you’re up close and personal,” he says, “your mind triages what’s most important to you.” It’s a survival mechanism, called auditory exclusion. The possibility that you may lose a little hearing doesn’t make the cut.

  A sniper also doesn’t, I’m guessing, pay much mind to the kind of thing I’m focused on right now: that raising your arms to hold a rifle while lying on your belly causes your ballistic vest to ride up and hit the back of your helmet, tilting it down over your forehead so that it pushes on your eye protection, causing the lenses to knife into your cheeks.

  “How do you do this job?” The petulant writer. Jack doesn’t answer for a moment. He must get this question a fair amount, and most of the people asking are not thinking about the aggravations of incompatible ballistic protection items.

  “There’s a lot to get used to.”

  I IMAGINE THE Special Operators were paid for their time today, but it’s also possible they did it for the steak. The Camp Pendleton catering staff have placed in front of Jack and myself a filet mignon the size of a grenade. Fallon got the fish. He looks like he’s about to cry.
