This is the rarely seen face of anti-terror policing on Britain's streets after the horrific terror attacks in Paris last week.
The officers were spotted at Wembley Stadium on Tuesday (November 17) during the England Vs France football match .
The unit reportedly wear fireproof military-style fatigues and a combat helmet, carrying a lightweight, semi-automatic rifle.
The officers also had a handgun in a holster strapped to their leg, with extra ammunition across their chests.
The Counter Terrorist Specialist Firearms Officers also have a Taser and Kevlar reinforced gloves to protect their hands.
A team of the officers, who are attached to the Metropolitan Police , were seen on Tuesday night's friendly between England and France at Wembley Stadium.
The team, reportedly comprising of 130 members, deal with firearms operations in the capital and across the country.
According to Met Police: "They are multi skilled and can deliver all elements of armed policing, including operations to combat major crime, hostage taking and terrorism.
"Their level of training, exposure and experience in dealing with such a wide range of armed operations lead many to consider the SC&O19 CTSFOs to be one of the world's leading specialist armed police support units."
Most of the officers covered their faces with balaclavas at the match, just days after 129 people were killed in terror attacks in Paris.
British authorities drafted in the country's premier firearms officers to protect the 80,000-odd fans at the stadium.
