Batou: When members of Section 9 are seriously threatened or injured, whether it's the Major, the Rookie, or the Tachikoma, he looses it a little. Certain abuses of innocents can also cause him to loose control, though usually not too badly (see: S1 ep.10 or S2 ep.18).
Gesicht: [SPOILER]
Robert: Being left alone.
Vimes: Vimes does not have breakdowns. He has Crowning Moments of Awesome. ...Well, okay, the injustices of the world turned him into an alcoholic for years and he had a breakdown in Men at Arms when he was taken off a case and being stuck in the past almost caused him to have a breakdown until he got proof that the future still existed. BUT GENERALLY SPEAKING, Vimes does not have breakdowns.
