“Push ’em out,” said Reno softly. And, somehow, they set off on twenty more repetitions of this killer discipline. Finally they finished, doubtless wondering, like the rest of us, what the hell they had let themselves in for. But I bet they never called out the wrong number of men present ever again.

I now understand that SEAL ethos — every officer, commissioned or noncommissioned, must know the whereabouts of every single one of his men. No mistakes. At that early stage in our training, our class leader, David Ismay, did not know. Reno, who’d only been with us for about fifteen minutes, did.

Again, he surveyed his kingdom and then spoke flatly. “Most of you aren’t going to be here in a couple of months,” said Instructor Reno. And, as if blaming each and every one of us individually for the wrong head count, he added, “If you guys don’t start pulling together as a team, none of you will be here.”

He then told us we were again about to take the basic BUD/S screening test. I graphically recall him reminding us we’d all passed it once in order to make it this far. “If you can’t pass it again this morning,” he added, “you’ll be back in the fleet as soon as we can ship you out.”

At this stage, no one was feeling...well...wanted. In fact, we were beginning to feel abandoned in this world-renowned military coliseum — a coliseum where someone was about to bring on the lions. Before us was the five-point screening test:

1. A 500-yard swim, breaststroke or sidestroke, in 12 minutes, 30 seconds

2. A minimum of 42 push-ups in 2 minutes

3. A minimum of 50 sit-ups in 2 minutes

4. A minimum of 6 dead-hang pull-ups

5. A 1.5-mile run in 11 minutes, 30 seconds, done while wearing boots and long pants

Only one guy failed to complete. In fact, most of us did markedly better than we had the first time. I recall I managed close to eighty push-ups and a hundred sit-ups. I guess the apparition of Billy Shelton was standing hard by my shoulder, trying to frighten the life out of me and ready to throw me out of the navy if I blew it.

More important, Instructor Reno was watching us with eyes like a fighter jet’s radar. He told me several months later he knew I was putting out for him. Made up his mind about me right then and there. Told me he’d never changed it either. Good decision. I give it everything. On time. Every time. Might not always be good enough, but it’s always my very best shot.

Looking back, I’m not sure that early test showed very much. There were a lot of heavily muscled, bodybuilding types who looked pretty ferocious. I remember they were among the very first to go, because they just couldn’t hack it. Their legs and upper bodies were just too heavy.

The SEALs do place a premium on brute strength, but there’s an even bigger premium on speed. That’s speed through the water, speed over the ground, and speed of thought. There’s no prizes for a gleaming set of well-oiled muscles in Coronado. Bulk just makes you slow, especially in soft sand, and that’s what we had to tackle every day of our lives, mile after mile.

On this first morning of Class 226, we immediately learned another value peculiar to BUD/S. We don’t stroll, walk, or even jog. We run. We actually run like hell. Everywhere. All day. Remember that great Tom Hanks line in A League of Their Own, “There’s no crying in baseball”? Well, we have a line in Coronado: There’s no walking in BUD/S.

Our first encounter with this cruel and heartless rule came when it was time for breakfast. The chow hall was a mile away, so we had to run two miles — there and back — for a plate of toast, eggs, and bacon. Same for lunch. Same for dinner. For anyone mathematically challenged, that’s six miles every day just to find something to eat, nothing to do with our regular daily training runs, which often added up to another eight miles.

That morning we ran in formation all the way across the naval amphibious base to the Special Warfare Center. And there Instructor Reno, after about a thousand push-ups and God knows what else, finally had us seated and paying attention in a manner which satisfied him. This was not easy, because he had eyes like a sea eagle and some kind of a high-flying business degree from USC. He knew precisely what was required, and he missed nothing.

And right here I needed to remember a lesson drummed into me from an early age by Billy Shelton: when a special forces commander makes even a slight reference to an issue that may be helpful, listen and then do it. Even if it was an aside, not a proper command, maybe even starting with I think it might be a good idea . . .

Always pay attention and then carry out the task, no matter how minor it may seem. Billy’s point was that these SF instructors were looking for the best, and it might be only small things that separate guys who are very good from guys who are absolutely excellent, outstanding. “Listen, Marcus,” Billy told me, “always listen, and always jump all over anything your instructor tells you. Get out in front. Fast. Then make sure you stay there.”

Well, that morning, Instructor Reno pulled himself up to his full height of about fifteen feet, in my eyes, and told us he wanted to talk to us briefly, and we better pay attention. “Better yet, take notes.”

I was into my zipper bag instantly, getting hold of a dry notebook and a couple of pencils, the lesson of Billy Shelton ringing in my ears: even an aside, even a suggestion, do it.

I looked around the room, and a few others were doing the same as I was, but not everyone, by no means everyone. Some of them just sat there gazing at Instructor Reno, who suddenly said, mildly, “How many of you have pencil and paper?”

I stuck my hand up, along with the other guys who had them. And suddenly there was a look like a storm cloud on Reno’s face.

“Drop! All of you!” he bellowed. And there was an unbelievable commotion as chairs were scraped back and we all hit the floor in the straight-arm rest position. “Push ’em out!” he snapped. And we made the twenty then were left in the rest position.

He stared at us and said, “Listen. You were told to have a pencil and paper with you at all times. So why don’t you? Why the hell don’t you!”

The room went stone silent. Reno glared. And since I was not able to write while I was prostrate on the floor supporting myself with the palms of my hands, I can’t say verbatim the exact words he said, but I bet I can come damn close.

“This is a school for warriors, understand? This is the most serious business there is. And if you don’t want to do it, then get the hell out right now.”

Christ. He was not joking, and I just hoped to hell he knew who had pencil and paper and who didn’t. Months later I reminded him of that day and asked him. “Of course I knew,” he said, adjusting his sunglasses. “It was your first test. I had the names of the guys who paid attention written down before you’d done your first twenty. And I still remember you were on that list.”

Anyway, that first morning, we did another couple of sets of push-ups and somehow gasped out a loud Hooyah, Instructor Reno! And then he let us sit down again.

What followed was probably the most stern lecture in SEAL ethos and ethics I’ve ever attended. I did take notes, and I recall everything he told us, and I’ll try to relate it as I believe Reno would wish.

“This is high-risk training. And we define that as anywhere there is potential for serious injury or loss of life. Any of you see anything unsafe, or any situation where you may be in unnecessary danger, speak up immediately. We do not like mistakes, understand me?”

“Hooyah!”

“Always remember your own accountability, to yourselves, your superiors, and your teammates. The chain of command is sacred. Use it. Keep your boat-crew leaders and your class leaders informed of any digression from the normal. And stay with your swim buddy. I don’t care if you’re going to the head, you stay right with him. Understood?”
