Errrm, I seem to recall that it was the UK military who fought Argentina for the Falklands, a UK territory. Many Scots, Welsh, and Northern Irish military personnel were killed and injured along with their English colleagues.
This UK/GB/English thing needs cleared up. Your football team represents England, not Britain or the United Kingdom of GB and NI.. The military is made up of personnel from the 4 nations. Your football fans should remember that the RAF is not "from England" when singing inaccurate songs!!
