Been thinking of the snipers that freed the ship captain held by Somali pirates last year. The snipers are on one boat bobbing in the sea, and the Somalis are on another boat bobbing on the sea. Obviously the boats are not bobbing in unison or even with any real predictive movement. How were they able to aim their shots so effectively? Is it just superb marksmanship or superb marksmanship combined with some sort of high tech, computerized aiming system?
