Ctf Ai

I'm working on a forest-type CTF map... Anyone have any ideas of how I wound do Single player AI for it?

I think you could do the attacking and defending easily with ai scripts.
Additionally make a trigger that detects when the ai player caputures a flag or his flag is captured, that sends ai signals that stop the standard ai, and specially handle those situations using triggers.
Then when the flag is back in the base, send another ai signal to switch back to normal behaviour.
