As an opening shot, Military, possibly Auz.

Military, not Aus, but with a modicum of GA use.

What sport would be played on that odd looking field at the top left of the pic I wonder?

This country lists rugby among its sports, though failed to qualify for 2019 World Cup.

I knew it. I saw the green green grass of home (UK)

Eastern Europe ?

Picking up on Dook`s suggestion of Eastern Europe, Romania back in the 1970s to 1990s had quite a formidable national rugby team. That said, possibly too much greenery & also everything too neat & tidy looking. My friend who has just bought me a cuppa, has just said is it Spain?

The hangars lead me to believe my earlier assumption of Blighty might be wrong. But surely, the surrounding terrain looks too fertile for sunny Spain?

Not Eastern Europe and not Spain. I gather Georgian props are a valuable commodity in the game these days. Spain may have been in the thoughts of the builders of this field at its inception.

Assuming Europe & Jenkins rugby clue, these are the countries that have been eliminated from the World cup next year.

Andorra, Austria, Belgium, Bosnia & Herzegovina, Croatia, Cyprus,Czech Republic, Denmark, Estonia, Finland, Hungary, Israel, Latvia, Lithuania, Luxembourg, Malta, Moldova, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovenia, Spain, Sweden, Switzerland, Turkey, Ukraine

Hmmmmm…. doesn't really narrow it down :)

edit: crossed with Jenkins post, so some countries eliminated.

Europe assumption correct. One must surmise that at the time of the publication regarding the 2019 RWC list this country was still in with a chance of qualifying, since it is not on the list.

From here https://www.rugbyworldcup.com/qualifying/europe
Germany is listed as "In progress"?

So, that's the country. Good effort but Samoa too strong. Now for the field?

Looks more like a pure athletics stadium than footy or rugger.

Munich area possibly?

Is it in what was formerly the DDR ?

As it's military, is it other than a German air force base ?

Not DDR, and not particularly close to Munich. A former Luftwaffe base, but no longer.

Sorry for delay, Salisbury Hospital since 0400.

Niederstettten.

I hope you are not unwell.

Yes, Niederstetten. Former Luftwaffe but current Army. Pedantry, sorry!

All OK, huge variety of health problems take me to Odstock. This was 0400 arrival at A&E, now clear for home, 1500. Wife and I visit Derriford in Plymouth wherein lies wife sister from Kingsbridge. Hospital chaotic, but ward cheerful with several military staff. One expressed a desire for an Aeromed posting. I explained that my first Aeromed had been off the grass at Plymouth in 1970.

A vous.
