Harrison, having no cover in his present location, did the reasonable Marine thing: shout an oath at the tangos and throw himself onto the ground. He belly-crawled towards a traffic barrier on the side of the street and removed the Longbolt from his back. Admittedly, he had never fired a sniper rifle before, and had only the barest in marksman training, but from what he had heard the calculations required for artillery support and marksman support were similar in nature. Not exactly the same, but close.
Then again, the Marine he had been speaking to was about a half a stein from being under the table at the time, so the ex-mercenary was probably wrong. Harrison scowled, poking head, shoulders and sniper rifle over the top of the barrier. "Oh well, what the hell," He said in a singsong voice, bringing the scope to bear on the first of the tangos that had taken cover behind the third car. He aligned the sight's distance markings on his target, took a deep breath, held it, and squeezed the trigger. After firing, the ex-mercenary immediately crouched below the barrier and cycled the bolt on the Styrling-made rifle, noting how smoothly it moved before the next round settled into the chamber, and then looked for another piece of cover to move to.
