Russia proves why we need a new tank.
It takes YEARS to develop, produce and field such a weapon system.
There is no civilian industry for many components, no off the shelf solution, and much of what is required to manufacture a tank needs long lead times to set up.
Do you have a foundry in your backyard? How about a gun tube, what aisle is that on, in your local Walmart? https://en.wikipedia.org/wiki/Watervliet_Arsenal
It has taken Russia YEARS just to ramp up production of a pre-existing design, where they are likely refurbishing and modernizing older T72s they have in storage (what the T90 is based on).
We too have huge stockpiles of M1’s: https://www.atlasobscura.com/places/sierra-army-depot
The Russians are pumping out a lot more tanks as they are getting shot up.
Quantity is a quality in it’s own right.
But it is not what we should rely on to win a fight. The lives of our people matter.
Did you even read post 23, and what I responded to?
