London's Underground, A Battlefield? The recent scenes of Nato forces taking over a disused platform at Charing Cross Tube station in London have sparked both fascination and concern.
The UK led Nato Allied Rapid Reaction Corps (ARRC) has been conducting Operation Arcade Strike, a simulation exercise designed to test the alliance's capacity for "deep strike" operations against Russia.
The exercise echoes the Blitz era, when civilians relied on underground tunnels to survive Hitler's bombs, but it also serves as a stark reminder of the UK's lagging military capabilities compared to other European nations.
