Re: The peaceful revolution
There is not much to go with T-14 so far. Apparently it is about 10 tons lighter then Leo 2A6, while having a similarly powerful engine and bit higher top speed compared to Leo. It would seem that T-14 is similar in size to T 90, but it costs double the prize. It would be only logical to think that extra money has been put into some improvements compared to T 90.
Edit: How on earth this post appeared in this thread?...Uhm, maybe a kind Moderator could move it to the T-14 thread.
Re: The peaceful revolution
The tank being more or less invulnerable to attacks seems a bit like an exaggeration, one just needs to look at some youtube videos and assume there is no super secret tech yet to see that this claim is unlikely.
First of all two videos showing the tank and that it apparently uses the somewhat older Drozd active defense system, which also seems a bit directional and only covers the frontal arc:
The first video also mentions a defense against cluster munitions although that seems to hinge mostly on jamming sensors with smoke so that cluster munitions cannot actively aim for the tank or so.
The Arena system is really impressive but a)doesn't seem to have made it into the first version of the Armata (could probably be added later) and b) isn't demonstrated against a sabot, I haven't seen an active protection yet that actually works against a sabot and I would assume that the reaction time is a big problem there since a sabot moves quite a bit faster than a missile and would probably require quite a strong sensor to discover it early enough since it is also really small.
