So far this is the only argument you have been able to conjure. Firstly I dont consider an average American soldier to be an expert in Russian military hardware.......let alone understand the overall strategic advantage (as opposed to simply evaluating the performance of the equipment), or understand the situations they are designed for or the doctrine to be applied to leverage their advantages.
Fact is a lot of Russian equipments have won foreign contracts beating comparable US contenders in the fray.
Because it’s cheap to make, cheap to sell and lousy to use. Do what I suggested to you pal and adios. You’re boring.
