Conquistadors.
Didn't I have several Workers stacks before that sneak attack?
As useless as they may seem for the human, it is the most deadly UU in the hands of the AI. Spain did sneak attack me in a CotM (the Austrian one), and managed to capture/kill about 20 Workers, and a city 6 tiles away from my borders. And no, it wasn't undefended; a Hussar and a MDI...
Berserks...not really. Never seen more than 2 in an AI ship. In the Middle Ages conquest, they are really a nemesis; but in unmodded, oh well.
All those Defenders are painful, no way to avoid triggering their GA.
Keshiks can be ugly when coming over mountain ranges, but that is a rare situation.
Sipahi are a indirect problem; the AI cannot defend against them before Infantry, and thus Ottomans often become a real runnaway Civ if on another landmass.
Oh, and the F-15 can be a pita as well. Really.
Had to face it one single time in my Civ carreer, admittedly; but, America as strongest AI, with their very own continent...I simply didn't manage to capture any coastal city. All bombers were shot down (yes, that did trigger Abe's GA), and ships didn't work since he had stacks of ships in all cities as well.
Of course, the F-15 isn't better for intercepting than the regular Jet - but, America builds tons of it...
