And as for Russian tech in general. I actually concur with your doubts on its general efficacy. Most of their stuff is usually a generation behind comparative US hardware .....and our software is almost always better. On that we both agree.
However every now and then they come up with something we do not have. One example that i gave in my first post is the Arena system in their tanks (that we have been trying to get for our M1A2 Abrams) ....and by the way strangely no one has been mentioning it (just concentrating on the mine detonation device and whether or not it works on RF principles ...but no mention of the Arena or the Shtora. Hmm). Another example is the Shvkal hypercaviating torpedo that can travel up to 4times faster than anything we have currently....especially the 2nd generation Shkval (which is by far much better than its predecessor).
Anyways i am not here to argue about US versus Russian capabilities. The answer to that question is a given: US stuff is better since it usually has better software, and is usually a generation ahead of the competition. The good Russian stuff is either in experimental stages (and due to the financial state of Russia most of it stays there ....or gets released when the US already has a better system), or otherwise is produced in such small quantities as to be virtually negligible (a good example of this is how Nazi Germany came up with the jet plane at the end of WW2 but the numbers were too few to make any impact ...and anyway the war was all but over). Most Russian stuff cannot compare. On that we agree.
However there is some stuff like the Arena system that even we do not have a substitute for.
