Having operational aircraft telling the world where they are isn't exactly a strategic or tactical plus. 
Honestly, I'd be surprised if any military has their operational units blathering about where they are. 
Been wasting my time watching them again on
https://tar1090.adsbexchange.com/- A Swedish ELINT Gulfstream was flying patterns along the length of the Baltic Sea.
- An AWACS type thing was flying a pattern over Poland.
- A
U2 came from the direction of England at 60 000 feet, towards the Baltic sea.
- Once the U2 was over Denmark, the Swedish Gulfstream left, disappeared for some time over the island of Gotland, and went home.
- A US "Something" was flying circles over northern Poland, and then flew as if to join the U2, but at much lower altitude.
- The U2 and the "Something" disappeared from tracking, south of Sweden.
- A British Eurofighter came over the North Sea but turned towards land over Poland, and disappeared on the Lithuanian border.
Now, more than an hour later that US "Something" is back over the sea between Sweden and Poland.
edit 1.5 hours later:
the US "Something" started going south-east about 32 000ft and 400kts, and crossed into France at Mulhausen. Where is it going? Oh. It turns towards Italy. It went around Switzerland.
No further sight of the U2.
edit after 2 more hours: at some point the US "Something" disappeared before reaching the southern end of Italy. I think it must be going to Cyprus. Could ba a tanker. Maybe the U2 is with it?
There's a multi-national Naval excercise going on in the Baltic.
