__NOWYSIWYG__ Use an Aquila, and take the head and wingslot off. Replace the arm with an Armoured Arm (the default arm for the Slave chassis) and equip it with two Rifled Sniper Cannons in the correct weapon slots. Play rated games, and try to kill high-tech valued sentinels (a reasonable Hurricane is good enough). Killing Ba'al Lord of Illolia, the golden babel boss that randomly appears in rated Warzone games, during a Standard-tech game will unlock this achievement.
