Smile, remain calm all the time, ask, tell, expel, and try to forge a positive relationship with the technical area occupants early on. Determine who the conciliators will be and who the troublemakers will be early on and use that to your advantage.
More to this point: "It's difficult to say, coach, because our angles are so tremendously different. What I can say from my angle is that your behaviour is getting tremendously close of irresponsible so you should calm down before I have to take action." is a great quote.
