Mechanization played a roll in that

Once we started mass producing IFV's, APC's, tanks and really phasing out the horse cavalry and foot components, the military required less men and instead more training.

if you go into Moscow type warfare, where the Germans had to go street by street

then poorly trained militias actually have the advantage if it's nationwide rebellions

because our own forces, while very trained and well equipped, take a lot of time and money as a result to be sent to the front

and when there, it'll be hard to get reinforcements in a civil war situation with possible insurgents on all the major supply routes

the U.S. military relies on it's logistic capability to accomplish what it does around the world

without that advantage due to the conditions, this is a war that'll last longer than a purge

and make the Syrian civil war look rather tame in comparison

War is logistics

the Germans didn't have the gas to blitz moscow, after having to go as far as they did into poor infrastructure russian lands

most of their motorized supply units broke down in the first six months

being irreplaceable

supplies took longer to get where needed, and the Russians blew up the caucaus oil fields

costing the Germans the needed resources to sustain a mechanized/armor thrust

in a civil war situation, depending on the organization and how widespread the rebellions are

the U.S. Military is likely to find itself in similar dilemma

and that there, is where it will fall apart

we've seen Afghanistan

In this sorta scenario, the technology difference doesn't matter

The Taliban owns over half of Afghanistan and government forces have lost entire cities to the insurgents in recent months

and that's with U.S. military support

The only way to win against people like that is old tactics

Roman tactics

enslave the people, salt the fields, burn the towns, poison the wells

but no one has the gall to do something like that

so as a result, the war is unwinnable

The Italians started using old Roman tactics like that in their Libya campaign

after over 20 years of occupation since the Great War

they'd been facing Islamic insurgents

but it wasn't until they started making examples of the locals, throwing them in camps, destroying their food supplies, and using gas attacks, cutting off supply routes that they actually made progress and caught the rebel leadership

Unfortunately, that's war.

Sometimes to win, you really do have to be a cold hearted bastard to actually achieve your goals.

And I'm gonna be honest.

Those boys and girls in the United States Military don't have what it takes to take measures like that against their own people.

Nor really should they, given it IS their own people. But to defeat sustained rebellions that go on for decades. Sometimes it's the only way.
