They've got them peppered through the Urals. Lots of Cold War silos in that neck of the woods, and definitely active ABMs - saw them being driven just outside of astrakhan in the dead of night last year.
Also, kaz is full of Russian military hardware. Baikonur for instance is definitely covered by ABMs, as to not do so would be an untenable risk as far as Russia is concerned.
That's not news :) The reason these things are extremely off-road capable is so they can move around in the woods and the enemy can't take them out in a first strike attack. The retaliation capability is what creates the (desired) balance between nuclear powers. Same with nuclear submarines. Hide and seek for "grown-ups"...
Don't forget "passenger trains". Neatly dressed up to look like the express service, but chock full o' nuclear goodness. The roof peels back, and you can launch straight from the rails.
Yup, those would be the ones. Nice long convoy of them with APCs and tanks at the head and tail, cruising down the highway.
Seeing this kind of stuff is par for the course out there though. Drove from Rostov na donu to Stalingrad and there were huge (and I mean HUGE) convoys of tanks cruising down to syria's neck of the woods.
This isn't news to the world, it's just known stuff that isn't talked about as it doesn't mesh very well with realpolitik.
Edit: think there was also a satan in the convoy we saw, two massive stages on separate carriers. Proper "oh holy shit what am I seeing pretend I'm not here" stuff.
You haven't lived until you've sat on top of one (on its side!) waving a cowboy hat. Fond memories... Although I now also remember my lunch of various animal tubes on the same day. Damnitall.
