What is it that appears shit? Their AK-47 is one of the most popular assault rifle on the planet. Their MIG-21 was the most highly adopted supersonic fighter in history. Everyone seems to want to buy AS400 even though the US threatens them. Their artillery is good and effective, their cruise missiles are hitting targets with precision.
The SU switched to the AK-74 in oddly enough 1974, if google steered me right. It's popular in the third world because it's cheap and the build tolerances are so low it will tolerate lots of abuse. However the SU gave up on it 48 years ago. Sure the assault rifles are basic tech and it isn't like comparing a Sherman to a M1A2 but still they don't use it any more.
Mig 21 started production in 1959. What's next extolling the virtue of the British Army and Navy based on the Baker Rifle and the 36 gun Frigate. Also highly adopted, by who, WP countries who have no choice, China whose production abilities means they had no valid choice and various third would hangabouts in the Russian Sphere. Who gives a fuck.
I doubt anyone wants to buy the AS400 anymore or any other Russian equipment unless it's dirt cheap which was always their thing.
Artillery is good and effective and flattening residential areas but so what WWI artillery.
Ditto with their precision missiles. Also you present nothing about if they are actually good, I mean just because you can make a missile that go boom near the right spot, it's 2022, you know that right?
You are also ignoring everything else they have. It's a bit like bragging about your Lada, FIAT or Trebant because the rims are wicked awesome. 1: They arn't, 2: Even if they were, it's still a POS car.
You are just trying to hard and much like a covidiot seem to absolutely accept reality and evidence. Please embiggin terb by stopping embarrassing yourself. That would be cromulent.
