On arms in the world, you can really compare only the US and Russia. The United States is a powerful power with great production potential. For many years, the US industry has been developing and manufacturing weapons. In terms of the number of samples produced, the US surpasses any country in the world. The history of the creation of the military industry in Russia is much more interesting. I myself studied and worked for a while in the city of Tula. In those days, at the computer center, I calculated the area of ​​the enemy defensive line defeats when using the Hurricane (a volley fire).This city since the time of Peter the Great has become a real smithy of weapons for the whole of Russia. After World War II, the plants were developed in the Urals and became competitors of the Tula. All the years the scientific research institutes competed with each other and as a result they obtained unique samples, which are still used by the armies of many countries of the world. Despite many political events in the country, military production has been preserved, there were unique inventors and engineers, highly skilled workers at the factory.I have not been following the successes of our gunsmiths for a long time, but what has recently been announced and shown by Putin is quite true. In the west, after a shock, after a while, the media screamed in chorus that it was all a fake and nothing Russians had. We do not deny this, but why? Remain in the dark until we rearm the whole army. I think that the desire to bend us will pass like a child's measles. I can not understand, maybe because I did not get all that dose of propaganda by the ideologists of the world gendarme.Why do you think that if we are stronger, we will certainly attack? Why do we need this? After all, you can answer, and then what? Live with radioactive contamination underground, and then die of hunger? Great prospect for the winner!
