A 30 Odd 6 rifle:

I think they used this rifle in both world War I and somewhat in World War II as well.

Originally this rifle was designed to go through 10 men on a battlefield before stopping. So, it's original design was to literally wound or kill 10 men with one bullet on a battlefield. But, it also has another ability which likely it could be used for in the Ukraine war. What is this?

A 30 odd 6 rifle sometimes called the M-1 during world war II because of high muzzle velocity will go right through the engine block of most engines and cause it to stop immediately or soon thereafter never to run again.

That's right! So, one bullet properly placed from any M-1 Rifle will stop any truck or car driving down any road on earth.

My grandfather used one of these for bear Hunting in the 1920s in Washington and likely Canada as well. And yes, a 30 odd 6 bullet will also bring down a bear and most other big animals as well as the engine block of almost any truck or car made on earth. 

When the bullet hits it goes through the engine block this causes all the oil and anti-freeze to leak out and to continue to leak out from then on through the hole it makes. It also could theoretically cause the crank shaft to immediately freeze up or the engine to fly apart with no more oil inside. It also likely would pierce a gasoline or diesel truck and all the diesel or gas would flow out. So, I could see how an M-1 rifle with a scope or a sniper rifle which is a little higher caliber could take out all the engines of all the trucks coming into Ukraine from outside the country too.

I think most Ukrainian soldiers likely already know this about this old M-1 weapon used since World war I though by now.
