Why are the military at Wimbledon?

Answer 1

It's actually the Territorial Army.

The role of the Territorial Army is to defend British soil from enemies. They are the first line of defence if the United Kingdom is invaded, attacked or suffers a disaster.

The Territorial Army is extremely useful if the UK is invaded or attacked while the majority of specialist-trained military personnel are abroad, as it gives us a chance to defend ourselves while the military is being called back from behind enemy lines to defend their homeland.

The Territorial Army are at Wimbledon tasked with defending the civilians from potential terror attacks. They are equipped with specialist equipment capable of "sniffing out" material such as gunpowder, explosive compounds and biological or hazardous chemicals.

Don't worry. They are present at Wimbledon and the Olympic games to protect you.
