Violence of action is IMO the second most important factor that allows SWAT or similar teams to be successful (behind coordination and ahead of superior equipment etc.)
To be fair to Hobbs the Military and LE communities are very closely related and share plenty of their doctrine (especially in the case of SWAT teams who're to all intents and purposes paramilitary law enforcement groups). From what I've gleaned off of the numerous LE and Military members I've run into while Airsofting / my own research, two to the chest and one to the head is common in Military units and SWAT teams in keeping with the doctrinal 'shoot until threat ends' spiel. Some choose instead to only target center of mass, but there's a variety of factors that contribute to a head-shot being desirable as it's basically game-over.
