British army patrols Olympic RouteNews London, United Kingdom - 24 July 2012
Army guards patrol the Park Lane Olympic Route and the Queen's Guard Gate, on July 24, 2012.
According to an article in the Boston Globe, the army guards and soldiers were called in at the last minute, after G4S, the Games' private security contractor, failed to provide the promised number of troops. As a result, the British government called upon its army to provide 3,500 additional troops.
British Prime Minister David Cameron recently announced that 1,200 more soldiers would be asked to help with security measures during the Games. A total of 18,000 British military personnel will now be involved.
While the Olympics provide a festive event, the Games are also viewed as a potential security risk, due to its size and scope.
In addition to the British troops, many of the participating countries are providing their own security personnel. The United States, for example, will provide FBI agents for its VIPs and athletes.
