DEFCON post from Mon 28 Oct but may be pertinent - US sending warriors and material to Greece. BTW, DEFCON is a great resource - essentially it's a private social media of anons' eyes on defense matters. Usually pretty reliable.
Also, Russian subs are on the move in an operation not seen since the end of the Cold War!!!!!!! How the hell they got that many up and running is beyond me. Hopefully, no nuclear shit results from this.
First information after - the US relocate yesterday and today 1,700 US soldiers, at least 20 combat helicopters "Apache" AH-64D, 10 helicopters "Chinook" CH-47, at least 50 "Black Hawk" UH-60 (HH60) helicopters, as well to 2,000 military vehicles / units, such as infantry fighting vehicles in / over Greece's ports.
