Warhammer 40k: Adeptus Mechanicus - Sydonian Skatros

Sydonian Skratos is the supreme sniper sentinel soldier with the longest legs in the grim future. They take pleasure in taking out enemy troops or tanks with the choice of a radium jezzail or a transuranic arquebus, and while they rise high above the battlefield, they are difficult to take down - you can't even aim at them from more than 12" away.
