We’re giving them our older model stuff from the 90s. Compare that to the mothballed museum pieces Russia is rolling out.

Think about this for a moment. The USA is using its older stuff first.

You look at what Russia is using and you think it's old or not as advanced. Why aren't you making the logical conclusion (which is backed by evidence if you look) that Russia is doing the exact same thing as the USA?

Why is the USA's use of old weaponry simply that--use of old weaponry--but Russia's use of old weaponry is...something else? Corruption? Incompetence? Whatever other excuse you want to come up with?

It's safe to assume that Russia knows that the USA and other countries are going to send older reserves of weapons first. So it's not unreasonable for Russia to not use more than is necessary and bring in their newest and best weaponry.
