‘What type of kit are Hezbollah using these days?’ said Porter.

‘All kinds of stuff,’ said Sam. ‘They are pretty well financed, and of course you can buy just about any weapon you want in Beirut. It’s the B&Q of global terrorism out there. For assault rifles, it’s mainly going to be AK-47s and M16s you’re up against. For handguns, it could be just about anything. Berettas, Walthers, Brownings, take your pick. They use the good stuff mostly. None of that Bulgarian knock-off crap that blows up in your own face.’

Porter studied the desk. He hadn’t picked up a gun since he’d left the army more than a decade ago. Hadn’t even thought about it. Scanning the weaponry, he picked out a Beretta 92 pistol, a firearm he could recall training with back in the Regiment. The 92 was a short-recoil-operated, locked-breech weapon. It carried fifteen rounds, and its lightweight, aluminium frame weighed just slightly under 100 grams making it easy to hold, and even easier to slip inside a jacket or a pocket. It took a moment to reacquaint himself with the feel of the weapon, but once he curled his fingers around its cold, metal barrel, it was like welcoming back an old friend.

He took two strides forward. A white line was smeared across the floor, and the target was twenty metres away. Raising the gun with his right hand, Porter steadied himself, then lined up the target in the Beretta’s sights. He squeezed the trigger once, then twice, enjoying the powerful recoil as the gun kicked backed into him. A gun in your hand was like a suit and a tie: it made you feel like a man. It gave you power, and control, and certainty: and those were all the things you missed when you lived out on the streets.

‘An eye,’ said Sam approvingly. ‘It never leaves you.’

He was walking back from the target, noting where the bullets had struck. Neither was a bullseye, but both were close enough to it to at least disable an opponent, if not kill him outright. When you were in a firefight, that was all that counted, Porter told himself. If you wanted to kill the bastard, you could always do that with a double tap to the head afterwards.

‘Try it again,’ said Sam. ‘Legs a bit further apart, and keep your shoulders slightly squarer.’

Porter adjusted his position. He moved his left leg slightly, giving himself better balance, and relaxed his shoulder muscles. The pistol felt comfortable in his right hand, almost as if it was an extension of his own body. One squeeze on the trigger, then another. The noise of the explosion echoed around the room. Squinting, Porter could see where the bullets had struck: one just a fraction of an inch to the left of the target, and the second a bullseye.

Pretty good, he told himself. At least on a firing range. Combat will be very different.

‘Here, try this,’ said Sam.
