Don’t we have a bunch in National Guard stores?

Nope. Unlike the Russians, we stupidly do things with our armaments like turn them into a reef.

Cheap china steel kept steel prices down.

On the other hand, Russia has tens of thousands of T-34/85s, JS-3s, T-55s, T64Bs, T72s etc stored (most rusting hulks) as an emergency contingency to restore/rearm/resale....and they learned after WWII that the severe steel shortage they had, that they would never get rid of steel. They just stack it and store it. They have VAST war stocks that just need oil/gas to go. These pictures show the steel storage that would take MONTHS to restore.

Besides the steel the Russians are retaining supplies of spare parts they would not have to tool up to remake.

Remember reading years ago about the Soviets building bunker emplacements on the Mongolian and Chinese borders and instead of just machine guns they were installing the turrets from old MBTs.
Two men could command quite a swath of territory that way.
