The operation includes the unprecedented step of providing armed commandos on buses carrying athletes and officials to venues as well as lead vehicles with more armed officers.
Despite fears of terrorist attacks in the Indian capital during the Games, security has proved less of an issue to the Commonwealth Games Federation than the problem of missed construction deadlines.
Mike Hooper, the CGF's chief executive, said: "When India bid for the Games, the government gave an undertaking to provide a safe and secure environment if Delhi was picked as host.
"Seven years since then and there is nothing to suggest that they are backing off from the promise."
The country has been on high alert since the Mumbai terror attacks two years ago and high security measures have already been introduced.
Most tourist hotels have already installed metal detectors and perform under-vehicle checks as a matter of routine.
The Metropolitan Police has provided advice to the Indian authorities and will return to Delhi during the Games to liaise with the local police and to monitor security arrangements in preparation for the 2012 London Olympics.
The highly visible operation will be evident from the moment athletes and fans step off their planes at Indira Gandhi International, which will be secured by commando forces a week before the start of the Games.
In the city, the massive police and military presence will be supported by the installation of 2,000 CCTV cameras and continual aerial surveillance.
All Games venues will be protected by four layers of security, watched over by rooftop snipers. Fans will have to pass through metal detectors and have their baggage X-rayed before entering stadiums.
