In various threads, this one as a random example, the assumption is made that the US Army would naturally trounce any popular uprising because of it’s advanced technology.
I think such assumptions are too simplistic.
Before I start, I realize that a lot of this would depend on how a conflict might start. Let’s assume that the US government has gone rogue and is trying to suppress a popular uprising.
The high tech weapons the US Army uses against foreign armies would be extremely limited in use against a force of armed US citizens.
As Joe Random put it in the linked thread:
**
To this I ask: What is the US Air Force going to use the stealth bombers for? Militant members of a popular uprising aren’t going to be located in a remote bunker in Colorado that says “I’m a rebel, please bomb me!”. They’ll live as regular citizens, largely, blending in with everyone else. What use are laser guided bombs from a stealth bomber when you’re not facing enemy military installations or army units? Are you going to call out a stealth bomber sortie every time a sniper with a hunting rifle is picking off soldiers at long range?
Are you going to make B52 runs to carpet bomb Detroit because there are a lot of suspected rebels there?
Are you going to blow up downtown Miami with a MOAB?
On the contrary, a popular uprising most likely wouldn’t engender a cohesive, organized military force that the US Army has trained, and developed technology, to fight.
They can’t risk calling down artillery in the middle of a school yard, lest they piss everyone off and have anyone loyal to the (rogue) government change their mind.
So what does that leave you? Mostly small arms. Some heavier vehicles, depending on what the nature of the conflict is. If the government wants to present the idea of a small conflict against some “terrorists” that’s not serious, they’re not going to be rolling tanks down main street.
Assuming that the entirety of the US Army (and the various national guards) foregos their sworn oath and sides with the rogue government, you have what - 150,000 riflemen? I’m estimating here - 1.2 million in the US military, fewer in the Army and Marine Corps, a small percentage being actual combat troops as opposed to support troops, and only a fair percentage of those being riflemen - others being dedicated to heavier weapon systems of dubious value in such a conflict, spread across the entire US.
On the other hand, you have 80 million gun owners - many of whom have enough weapons to spare should others wish to join in any rebellion. Let’s assume that 10% of these people decide to act against the government (which, I think is a very small number if the government truly ‘goes rogue’), and, say, a quarter of them recruit one friend. That’s 10 million people.
Not only that, but millions of them are experienced hunters. Skilled in woodcraft and marksmanship, armed with ubiquitous deadly and accurate hunting rifles, they would make a fine improvised sniping force.
US Infantry doctrine isn’t based on anything resembling being able to fight and outnumbered by several times people who have more accurate, longer ranged rifles, skilled sufficiently in woodcraft to succesfully evade often retribution, able to slowly pick away at a numerically smaller and somewhat isolated (due to the vastness of the US vs number of troops) force.
Sure, many of them would be shot and killed - but if they took a few with them, simply by attrition the US army would be quickly wiped out. The Army can’t use heavy weapons against someone who shoots a soldier on a patrol from 600 yards away and then evades them in their own back yard. Not effectively.
So we have riflemen vs riflemen. Iron sights from a relatively short ranged M16 against a long-range, accurate, scoped rifle such as the ubiquitous Remington 700.
An army under dubious morale conditions (I mean, really, how many in the army are truly going to be comfortable shooting their fellow citizens in the name of a tyranical government?) against determined fighters fighting for their freedom in their own back yards, armed with weapons ideal for such a conflict, and greatly outnumbering said army.
Such sniping tactics are often just as effective in urban areas, which are extremely hard for any organized force to fight on. If soldiers were enforcing martial law on the streets, it’s not unlikely that small patrols would take high casualties from people hiding in buildings, people that wouldn’t be easily located.
Assuming a generally sympathetic populace, it wouldn’t be hard for these people to hide. The army can’t go around killing people they merely suspect because that would turn any support for them around immeadiately. Hell, people might not need to hide - they could live a normal life 99% of the time, and take whatever action they could against the government when the opportunity arose.
And this is assuming a worst case scenario in which all of the military and national guard fully complied with a tyranical government. A much more likely scenario is that large factions of these groups would decide to fight the factions that remained loyal to the tyranical government. In this case, the military aided by millions of willing and ready citizen-soldiers is pretty much garunteed to win.
Anyway, the main point is that people assume that high technology heavy weapons would easily decide any conflict, when the reality is that because of the nature of the conflict those weapons would be nullified.
I’m not saying that citizen-soldiers would automatically win any conflict, and of course a lot depends on the exact nature of it, but I think the assumption that the army would simply trounce any armed resistance is flawed.
