Earlier quoted context omitted.
You could say it the other way around - once the tank stocks are depleted, anti-tank weapons can still play a devastating role (against other armored or unarmored vehicles).
You could say it the other way around, but the complexity of the electronics in the anti-tank weapons have proven to be difficult to produce in large quantities because of the chip shortage, but also because of the high level of experience and knowledge required to continue to make them. Tanks are much less reliant on complex electronics and manufacturing capability in order to be effective on the battlefield. The US…
Reponding to this and some of your other comments elsewhere... These anti-tank weapons may be the best anti-tank weapons, but they're not the only ones. If all of these are used, there are plenty of other ways to destroy tanks, so it's important, but not required to have a large stock of them.
You could probably increase the rate of manufacture of these, but there's also value in having ten continuous years of manufacturing instead of long time periods between batches.
I may be overly cynical, but in some ways, this war seems like a warehouse clearance event. It seems like everyone is finding their old stockpiles of Soviet era equipment and sending it to Ukraine to be used and/or destroyed. And presumably afterwards, it'll be time for the military industrial complexes to turn back on and build new stockpiles. Add in a few field demos of new equipment too.
