This is the sort of thing that confuses the hell out of me, uninitiated with military matters.
I clicked on the website link and ran it through Google Translate. There's no actual date when the video was taken. The text doesn't explicitly refer to this as happening right now. It could be part of the 'massive drills' that were taking place up to yesterday. Or it could not.
C-400 put on combat duty
The first regiment of the Northern Fleet Air Defense, equipped with the latest S-400 "Triumph", who took on combat duty in the Murmansk region. Currently in conjunction defense of the Northern Fleet combat duty carry anti-aircraft missile regiments equipped with the S-300 and S-400. They cover from enemy attack from the air the regional industrial and energy facilities, points-based forces and troops of the fleet and transport communications. The newest system S-400 "Triumph" can lead simultaneous firing of up to 36 targets with guided missiles on them 72 at a distance of 400 km. Video Ruptly.
Does anyone have any confirmation from more than one source that the drills have actually ended? AFP keeps coming up on various websites, but nothing else.
