In general I think it is 'The UK establishment' that uses QFE. Its use elsewhere is limited.
In terms of armed services, I believe there was a thread about a year ago that concluded that QFE's use by armed forces outside the UK was limited. A lot of country's forces routinely operate into fields that you couldn't practically use QFE for.
