AI Scripting
AI Scripting is one of the most important additions to the engine of U2, at least as far as map making is concerned. It allows enemies (and friends) to be controlled easily via external .ucs files that can be easily changed without map rebuilding. Almost every important NPC (non player character) in U2 has a long and detailed script behind it controlling its behavious and actions under various conditions.
scumble: The developers called it "AI scripting" so it might make sense to use that terminology. Also, technically, not all Pawns can necessarily use scripts, only if they use a subclass of U2NPCControllerScriptable.
Tarquin: Everyone ok for a move to AI scripting
ZxAnPhOrIaN: Sounds good, because pawns can be AI, and AI can't be pawns.
