I agree with much that is said here re opsec on SPECIFIC events, eg the idiot who identified the GR4s accompanying the tanker northbound. However, even I who have been out of "the loop" for 25 years can put two and two together and assume that where there are tankers in a seeming towline over Eastern Europe for hours on end that there will be some sort of tactical asset depending on them, especially as the strategic assets don't go anywhere near them. As they are showing up on ADSB I can only assume that NATO wants the Russians to know they are there otherwise I suspect their mode S would be quickly switched off, as are most of the tactical assets in the UK airspace. Now, if I can work that out perhaps Ivan, whose sole job is to gather intel on what is where and when, can also work it out and that all the BEDEWINDOW criers on here could maybe understand that and stop calling people with an interest in this sort of thing names?
