I´m not too firm on modern British uniforms, though - is this a "current" uniform or an older pattern, IE maybe usable for the Falklands War (which is another interest of mine... )
This is Afghanistan/Iraq current by the looks of it.
The SA80 is a dead give away, as is the combat vest and tactical net. The Falklands was fought with the SLR (FN-FAL) - on both sides I believe.
HTH.
