been a while since there's been a head to head competition
but back in the 80s/90s there was a track record of Russian equipment vs western equipment
Russian equipment did not fare well, in fact that is why we have the Israeli Arab situation of today
Russian equipment fared very badly
but you can never rest on your laurels, it's always a new day and you're only as good as your performance out in the field
like the Kalashnikov? Back in the day TRW produced a simple combat rifle [for the Pentagon] which was cheap and did not jam. It was too elegant and cheap for the USA government so they turned it down. They like wasting money on expensive stuff that breaks down.
