Don't worry, war hasn't arrived in Manchester, nor has the city descended into 28 Days Later-type post-apocalyptic madness.
Those army helicopters you keep seeing out and about - actually called Pumas - above Manchester and Liverpool are all very routine and nothing to be concerned about.
The Twitter account for RAF Benson, a helicopter base in Oxfordshire, has tweeted that the Puma helicopters are operating in the area to "hone their skills operating in urban environments before deploying to Afghanistan," and that they will be using "authorised helicopter landing sites in the area."
The Puma helicopters are four-bladed, twin-engined medium transport and utility helicopters that were first introduced in the 60s and there have since been many more advanced models.

The upgraded aircraft currently used by the Royal Air Force can transport double the payload over three times the range than its predecessor.
They will be deployed for tactical troop transport, as well as fast moving contingent combat and humanitarian operations.
