Guerrero grabbed one of the boxes and unlatched the top, revealing very long bullets, longer than what Marco had shown her. Oddly, they were all attached side-by-side to each other by some sort of small black chain. Offering one end to Stavrou, the Marine opened a latch on top of the large gun, inserted a bullet, and clamped it shut. He then finished off by pulling a handle, almost similar to the crossbow notching rod, making an audible click.
