1812 US and Russia get T-14 Armata Tanks

And do not know how to use them. All the manuals in the world mean nothing if there is no industrail supply chain to support the artifact.

This means oil is first on the list. No fuel and no lube means a paperweight

Besides the Armata is a lousy tank. 

No fuel, no ammo, no lube, no rubber, no tools or even the materials to make the necessary tools. Russia doesn't even have basis steam engines in any significant way at this point, nor a large number of literate machinists.

Manuals to make more tanks? More than just a little silly. These aren't things that can be bashed out in a blacksmith's shop.

That is the point. The US, Russia and their enemies would be forced to start with WW1-esque tank designs while jumpstarting the Industrial Revolution!

The Tank causes a technological arms race

It's Canon and Machinegun also cause nations to change how they use infantry and artillery

Even the cannon and machine guns are well beyond their capacity at the time, or even the capacity of the most advanced British industrial concerns of 1812.

The Industrial Revolution had already started at this point, but it couldn’t cope with the materials and level of advanced materials. If these were Mark I tanks, there would still be an issue, albeit not as crazy.

First farm tractor...

Bemjamin Holt.



Despite what the British claim that was not the first practixcal tractor. We had seen earlier Russian and British failures which had got stuck or were impossible to turn without track throw off the idler or drive wheels. Holt was the first to make a commercially successful and engineering sound agricultural or industrial mining version of a track laying machine that could move under its own power. The Holt was painfully slow and had an enormous turning circle.

Now let me give you some background...

Neither the British, the French or the Austrians were stupid. As soon as trench warfare showed up, General D'Estienne and the Churchill Admiralty Investigation Committee instantly looked at the American track laying technology as a possible method for crossing no man's land to increasxe the rate of movement to give machine gunners less time to chop up French and British infantry. The idea to get the machine in there into the enemy trenchs to kill the machine gunners was probably more British than French, since D'Estienne was more concerned about German artillery from what he saw, but the point of moving faster and with more agility and also cross trenches, which a Holt tractor could not do, was the main point I want you to consider. The investigators merely started with the Holt as a start point. They knew thay had to do much better to meet the conditions they faced in France in 1915. 

Given that, it was still this design that formed the initial basis of char d'assault research for the British and the French who immediately bought samples and tried to reverse engineer the Holt track laying system. They ran into problems. Patent infringement was not one of them, because they were desperate. They found the turning circle of a Holt too large, the weight of the tractor to track area flotation too heavy for the mud to float (Floatation is the correct term, since vehicles FLOAT on the earth when they exert ground pressure.), too low a coeffecient for traction in simulated Flanders mud they used for their tests and just too slow. The Holts sank and became stuck in place for both the French and the British.

It can be said that the Admiraty Investigation Committee and Renault, independent of each other, actually invented track laying systems that were effective in climbing into and out of trenches or crossing them, and somethiong which could cross bogs something which the Holt system could not do and which this absurdity:



The absurdity.



could not do either.

So, we drop an Armata 14 into 1914 instead and ask ourselves the same questions the 1914-1916 era tank investigators and developers did. They would comprehend the Armata and understand what it was and could with the means they had, build a facsimile as to function. 

They would ask these questions of it as to your OP but with what these investigators knew they wanted.

1. Can it float?
2. Can it cross a trench?
3. Can it hold traction and not get stuck and SINK?
4. Will it run from A to B reliably?
4. Can we make it?

Let me answer that for you in 2022 as we KNOW now.

1. On concrete and macadan roads we have seen it float.
2. No.
3. No.
4.
Definitely no.
5. Why would we? It is a RUSSIAN tank, i. e. a piece of garbage.
