For fifteen years, I trained Marines to turn nothing but their bare hands into deadly weapons. I was the master hand-to-hand combat instructor for Force Recon and MARSOC Raiders at Camp Lejeune.

I slowly raised my hands to shoulder height, keeping my breathing steady, my mind calculating distances and angles.

Stepping out from behind a forklift was a man in his late thirties, wearing a tactical vest, combat boots, and holding a silenced MP5 submachine gun pointed directly at the center of my back. He had a military tattoo on his right forearm—the insignia of the 2nd Marine Raider Battalion.

"Sergeant Miller," I said quietly, recognizing his posture. "Class of 2014."

The mercenary froze for a fraction of a second, his eyes widening slightly as he looked closer at my face in the dim warehouse light.

"Master Sergeant Vance?" he gasped, his weapon dipping by two inches. "You're... you're the instructor from Lejeune."

"I taught you how to clear rooms in Fallujah, Miller," I said, turning my head slightly to keep him in my peripheral vision. "I taught you that a weapon is only as good as the discipline of the man holding it. Now you're taking dirty money from a low-life mobster who abuses young women?"

Miller's face flushed with shame, but his grip on the submachine gun tightened. "It's business, Chief. Frank pays three grand a week. The Corps didn't give me jack when I got discharged. I gotta eat."

"You sold your honor for three thousand dollars a week?" I asked softly, my voice dripping with pure disgust. "You're a disgrace to the uniform."

Miller’s jaw clenched with anger. "Shut up! Drop your belt and get on your knees!"

He stepped forward to kick my legs out from under me—a standard restraint technique I had personally taught him ten years ago.

It was his fatal mistake. He used my own drill against me.

The moment his right foot left the ground to sweep my leg, I pivoted my hips inward, dodging the barrel of his MP5. My left hand clamped down on the receiver, forcing the weapon upward toward the steel rafters.

RAT-TAT-TAT!

A short burst of suppressed gunfire ripped through the roof tiles, shattering the glass windows of Frank's overhead office suite.

I drove my right elbow straight into Miller's ribs, fracturing two of them instantly. I twisted the submachine gun out of his hands, stripped the magazine, and struck him across the temple with the heavy steel receiver. Miller collapsed to his knees, clutching his head, blood dripping through his fingers.

"Stay down, Marine," I growled, tossing the emptied weapon onto the floor. "That's an order."

Upstairs in the office suite, chaos erupted.

Frank Miller screamed in panic as glass rained down onto his desk. "What the hell was that?! Go check the floor! Kill whoever is down there!"

His three remaining armed thugs sprinted out of the office onto the metal catwalk, spraying automatic gunfire down into the warehouse floor. Bullets pinged violently against the shipping crates, throwing sparks into the dark air.

I dove behind a heavy steel forklift, pulling two flashbang grenades from my tactical vest.

I pulled the pins on both grenades, counted two seconds, and lobbed them over the shipping crates straight onto the metal catwalk.

BANG! BANG!

A blinding flash of white light and a deafening 130-decibel shockwave shattered the warehouse. The three thugs dropped their weapons, clutching their ears and eyes, screaming in agony as their balance centers were completely destroyed.

I moved up the metal stairs like a shadow. I disarmed the three disoriented guards with swift, brutal strikes, tossing their rifles over the railing onto the concrete floor below.

I kicked open the heavy oak door of the office suite.

Frank Miller was cowering behind his mahogany desk, a silver revolver shaking wildly in his right hand.

"Stay back!" Frank shrieked, his face covered in sweat. "I'll kill you! I swear to God I'll kill you!"

I walked up to the desk, completely unbothered by the gun pointed at my chest. I reached out, grabbed the cylinder of the revolver with my bare hand, preventing the hammer from striking, and casually twisted the weapon out of his trembling grip.

I tossed the revolver aside and grabbed Frank by his expensive leather collar, dragging his 200-pound frame over the desk and slamming him face-first onto the glass floor.

"Your debt is due, Frank," I whispered.

Outside, the air shattered with the sound of roaring engines, screeching tires, and heavy tactical boots pounding against the gravel yard. Bright blue federal emergency lights illuminated the fogged windows of the warehouse.

"FBI! OPEN THE DOOR! FEDERAL SEARCH WARRANT!" Sarah's voice boomed through a megawatt bullhorn outside.

Frank looked up from the floor, his eyes filled with absolute defeat as he heard the heavy battering ram strike the front gates.

I pulled him up by his collar, pinning him against the wall as Sarah and a dozen heavily armed FBI SWAT agents burst into the office, their rifles trained on every corner.
