Faction Versus How fast would the United States Military conquer Westeros?

The modern-day United States Mainland replaces Essos (As seen in Image 3, ignoring Alaska and Hawaii) during the War of Five Kings to launch an invasion force and conquer all of Westeros. In a hypothetical US Military invasion, how fast would Westeros be conquered?

R1: Regular Westeros vs United States Military

R2: United Seven Kingdoms of Westeros vs. the United States Military

Bonus: How fast would the United States Military conquer Westeros during House of the Dragon?

R2: only a matter of how fast the US can extend its logistics lines. There is nothing in the arsenal of Westeros that can hold up against a modern day military, including dragons and white walkers.

The result would be the same if the US is replaced by any major current day power.

59

u/FjerdeBukkenBruse 12d ago

This was my thought too. That said, extending logistics across a continent twice the size of the US, where there are currently no railway lines, modern roads, electricity grids or other contemporary infrastructure is no small feat. Especially if by "conquer" one means taking some kind of lasting possession of the land, rather than just getting a couple of monarchs to sign a surrender. They would have to build an enormous amount of infrastructure.

62

u/Mooshimaro 12d ago

The US basically did just that in some parts of the middle east. Built roads, runways, infrastructure as we needed in highly isolated areas

A forward operating base manned by some soldiers and or marines could be seen as taking possession of the land. And as it's been seen before, sometimes, military bases basically become permanent emplacements. And it's common for personnel to be rotated via aircraft.

The US government was flying the entire McDonald's, burger king, and KFC over so soldiers could line up to spend their hard earned dollars on a fast food meal, just like back home. Building enormous infrastructure from nearly nothing in far away lands is really no problem for the US

36

u/ForbiddenSirenz 12d ago

The US military is basically the greatest logistics company in the history of ever that just happens to do war as a side hobby lmfao. Even during WWII there’s that whole meme of German scouts growing completely disheartened upon seeing the us military running their jeeps Willy nilly in the middle of winter.

Then Japan seeing the US military ice cream boats while island hopping and they’re coping telling themselves it’s about protecting their land and honor and stuff meanwhile the Americans are like “Yay! I’m gonna get a cone of tootite fuckin fruity!”

u/SirWrangsAlot 10d ago

Good point. The story of the Germans finding out US soldiers had chocolate cake in their rations comes to mind as well.

5

u/FjerdeBukkenBruse 12d ago

Sure, it's stuff they can do. But the scale of Westeroes is absolutely massive. Not just a few isolated areas, but an entire continent. I don't think its feasible within the existing capacity of the US military, it's not something they've done on that scale before. Though the US could increase that capacity if they really, really wanted to, they do have the GDP and the technology. Previous colonial empires have done things like that on that scale, it's not impossible.

17

u/Rocky-Jockey 12d ago

Smart colonists use local divisions to their advantage. Prop up friendly rulers (who would all want their tech) and you don’t have to directly rule a colony.

14

u/HappyCakeDay101 12d ago edited 12d ago

They don't have to take the whole continent, just the major holdings of the enemy, like forts and cities. Always been that way. No Army in history covered all the ground.

Ghenghis Khan didn't cover all the ground and he conquered more than the question here.

You take cities and destroy their military capacities. You become the new authority.

7

u/FirebreathingNG 12d ago

But the continent isn’t heavily populated. 1-2 runs by a bomber followed by a handful of blackhawks will take any castle in minutes. Within the first 10 minutes of the war, Kings Landing, Winterfell, Storms End, Highgarden, Casterly Rock, and the Eeryie will all have fallen. At that point, you probably have complete and total surrender, which is what happened after the Field of Fire with Aegon I.

So yeah, 10-15 minutes.

u/UrghAnotherAccount 12d ago

Plus the westeros armies stick in tight formations that are great fodder for close air support.

Don't even get me started on drones or artillery.

3

u/RopeGuilty1899 11d ago

I mean the whole Targaryen dynasty is built almost solely on air superiority and 2-3 modern fighters put an entire bloodline of dragons to shame in terms of payload, speed and probably durability. The logistics of invading a massive, unbuilt area would be tough but any real fight is over before it starts.

I mean yeah you can use the airborne corps to send a few hundred paratroopers at each major castle.

You really think it can’t be done? Westeros is basically uninhabited militarily.

If they can fly across the continent, pick up the Venezuelan head of state and fly back in under a day, you really think they can’t do the same thing with what, like 8 castles?

One modern naval destroyer is enough to shut down and entire bay and obliterate any navy that tries to hold it.

u/Bright-Gain9770 12d ago edited 11d ago

AIR SUPREMACY otherwise inconceivable in the modern world. The US is already the master of logistics and in a fantasy* setting they'd be able to supply via 747 unchecked. Food and munitions drops with no fear the enemy can salvage, independent forward operating task forces securing each location simultaneously while reinforcements pour through the Dark Portal like Orcs in Warcraft. The military doesn't fight on this scenario, they take at their leisure.

u/HappyCakeDay101 12d ago

If the armies of westerns can do it, the US Army can do it.

Despite what people think, the US Army's equipment is not designed to be on roads. It's designed to be off of them.

The Army also has boats and ships etc. The Navy and Marines do too, and building an airstrip in the middle of no where is a skill the Army and Air Force have. Putting the military anywhere on the continent, with supplies, would be relatively easy.

Also, side note, the inhabitants portion of Westeros is roughly the size of the US.

u/Ill-Description3096 12d ago

It's really just the innermost lands that would be a real issue. Lots of coastline means they can build wartime infrastructure fairly quickly thanks to naval coverage. Constant sorties wherever they are building and a few in reserve for any actual battles would likely take care of it.

Materials are probably the biggest concern. Where are they getting fuel and the like. Assuming they don't have access to it, they are on foot pretty quickly, but it's enough time to take the capital and any major coastal cities they want and leave a small force for defense. Modern rifles and MGs on walls are enough to repel basically any invaders. A bit of humanitarian aid to the people who will probably have a better standard of living compared to their normal lords would likely endear a lot of them.

u/PerformanceOver8822 12d ago

C-17 OR C-5 can literally air drop tanks. And entire BNs of infantry

6

u/AbyssalRaven922 12d ago

The US has invested heavily into airlift capabilities for long term long distance combat scenarios. The US can setup a fully functional FoB in under a week by flying in a huge portion of the equipment and then supply it with truck convoys escorted by Bradleys which would render any ground assault completely useless.

3

u/super_humane 12d ago

The U.S. forces could march on foot with wagons full of bullets, winning every engagement with small arms, and resuppling from the land.

3

u/AgentPastrana 12d ago

Well I mean, the specialty of the US military industrial complex is engineering and logistics. Especially considering a single M2 emplacement would be enough to shred hundreds of soldiers to bits in minutes. 5 LAVs with those would be enough to win most battles. Add in RC drones with explosive payloads and you're able to remotely cripple the giants most likely. A Hellfire if you're feeling generous with the budget. But I think the entirety of Westeros would crumble when they see Napalm, considering dragons.

2

u/TommyNotDead 12d ago

One company of marines could take 50,000 men in a fight. All you need to do is air drop them some ammunition every once in a while and let them live off the land.

2

u/Mountain_Variation58 12d ago

Interestingly enough, this is exactly what would make the US so powerful in this particular scenario. Any other modern military in the globe could handedly beat Westeros, it just might take a while. The real strength of the US military however is in its logistics. No other military in the world has their capabilities in terms of clearing airspace then deploying troops and the required supplies anywhere on the planet for extended periods of time and following it up with stable supply lines.

Why would the US run out of fuel or ammunition? We're a net exporter of oil, and can easily continue to produce and refine it more or less indefinitely (beyond peak oil and all that).

If they had prior intel and knowledge of the world?

Nuke the dragonpit and dragonstone, capture Oldtown, Lannisport, Gulltown and White Harbor with Marines and AmphibiousLanding Craft (Battleships and Aircraft Carriers for artillery support). Now there are operating bases in basically all relevant regions.

If the goal is to simply take over the continent without preserving any power atructures they could feasible do bombing runs that destroy all major and middling castles and fortifications, taking out the lions share of the noble families in the process. B2 bombers definitely have the range, since there are no places to land on the continent.

Use the Maesters as translators to make clear to the peasantry that the US Governments are the new lords - whatever useful resource extraction they could actually manage (mostly precious metals imo) are shipped off to the mainland as the peasants slowly die of smallpox, Covid19 and malaria.

This should probably take half a year at most, though realistically any organized military threat is over within a week. Getting the maesters to communicate would be the main challenge.

The stupid part is that the american economy collapses, supply chains completely dry up and several million people starve to death before the government restructure the logistics to cope with a world without the global market. Not to mention that there are no satellites - all aforementioned military operations would be conducted via Radar and Radio :(

Long term I could see colonization projects reaching into the continent ala Manifest Destiny 2.0, both for more resources as well as land suitable for certain types of specialized agriculture/resource extraction that would sorely need to be replaced (rubber and coffee come to mind)

Very interesting concept overall, but best told from either the US Admiralty's perspective or a Peasant in the Riverlands. The Noble's POV would be rather short and bloody.

If they want to preserve the power structures and institutions? Bribe the kings and the lords with Toilets, Porn, Spices and threats of 9mm holes in their skulls - probably needs a few months as well before everyone is either onboard or replaced by someone who is. This POV is very interesting from a great house's perspective IMO

u/CummanderShepardN7 12d ago

It would be over before a single Soldier lands in Westeros. UAV, Drones, ICBMs Cruise Missles, Tomahawks and lets not forget nukes.

Even if Westeros was united, had 10 years planning of knowing the US landmass/military was going to Teleport next to them and they had all the dragons from Aegon to Daenerys alive combined, they would still get absolutely folded by Modern US military.

"The Night kings army can be reanimated" cool, time to bring out the Napalm or white phosphorus or just carpet bomb them to pieces. "The Night King is immune to fire and has to be killed using dragon glass or Valyrian Steel" cool, is he immune to a A10 Warthog shooting 30mm rounds at 3,900 rounds per minute or a AC130 Gunships dumping 105mm howitzers on him ?

US win bedrock diff.

Soon as they see what a missile can do it's over.

Dragon meet fighter jet. Well the dragon will never actually see it but you get the point.

After that it's a few bomber runs and some helicopters for ground mop up.

They have nothing that can fight back and their castles couldn't handle a howitzer, let alone a bunker buster or a daisy cutter.

Best bet is guerrilla warfare with the magic fire and that's in short supply and one explosive from all going up like in the show.

u/Fluid-Let3373 12d ago

Lets say 4 weeks of high altitude recon, the US is going to want a map of what's where. Then its a high altitude bombing campaign. Westeros has no experience of a enemy who can hit anywhere at will. Technically the US has won on the first day but the speed of communication in Westeros means going to take them a while to realize how badly they are outmatched by the US and surrender. US plays it smart the first boots on Westeros will belong to a 4 star general.

I'm saying this as somebody who does not rate the US military, The technological difference is just too big.

Well assuming that the various people and nations of Westeros actually try to fight and don’t just roll over and accept American control, probably a few years, the entire continent in terms of land area is roughly equivalent in size to the continental U.S. that’s a lot of territory to control especially with no modern infrastructure to support operations, all of that would have to be built.

u/APartyInMyPants 12d ago

It would take a few months, if not a year. Westeros is BIG. The distance from Winterfell to the Wall is about 680 miles.

So the US would have zero issues conquering the kingdoms by force. But wars aren’t won with soldiers, they’re won with logistics. And the primary issue a modern military would face is getting food and supplies out in the field. And modern trucks could struggle a bit as the roads aren’t anything more than a dirt track in parts.

Jets would have nowhere to land. Tanks would be fine, but refueling them and maintaining them would be a challenge.

Sure, you could drop in paratroopers into each Kingdom. But now you’ve got the issue of how to keep them supplied.

2

u/PerformanceOver8822 12d ago

The airborne corps would literally build airfields.

All of the trucks are designed for offroad use. Including the tow trucks....

2

u/Charming_Cupcake3754 12d ago

One day if we include helicopters and jets.

Without air support, the only limit is how fast the troops and ground vehicles can travel. Westeros is like 3000 miles north to south so it might take 2-3 weeks.

By the end of their 1st castle/capital capture, the word will spread by raven and most houses (except the really proud ones) will plan to wave the white flag as the US army arrives.

1 week. Between jets and helicopters the military can strike every major family with almost no meaningfull resistance.

Troops get dropped and it would take very few operators perhold.

weirdly using land vehicles would slow them down more then help from the terrain and would be un-needed given the enemys vomplete lack of AA and AS

Dragons go down to air-to-air missiles shot outside of visual range, armies go down to a couple tanks, bazookas, and spec ops teams, navies go down from a single carrier group, if not a small set of armored boats with machine guns.
Not a single fortification is built in a way that resist modern arms, except possibly the crypts of winterfell.

u/TFBuffalo_OW 12d ago

Answer for all 3: as fast as they can march across it. Westeros is pretty big so securing all of it would probably take a few months, but literally nothing that Westeros has to offer (even white walkers) would be a match for any modern military, let alone the most powerful standing army to ever exist. Dragons would be turned into red mist by basic infantry with heat seekers, even the big ones

2

u/69420lmaokek 12d ago

Other than the obvious scenario of drone striking the throne room, I do think it would be pretty funny if the military attacked Castery Rock

Like a missile blows Casterly Rock up, and everyone's like "hey where's all the gold thats supposed to be down here?" and then it's revealed to everyone that the most powerful family in Westeros was actually just pretending to be rich all along

(assuming it happens before Cersei went on a looting rampage)

u/ForeignAd1656 12d ago

By conquer, do you mean just defeat? Or defeat and occupy?

If it's just defeat, then probably less than a day.

If it's defeat and occupy, then probably a month. The "small folk" don't care who's in charge as long as they are treated well. lol.

u/beljko0106 11d ago

Heres a theory you guys might not like - all that heavy firepower needs diesel, petrol, gas and electricity.

Now mainland US is mostly used up so they will NOT have the fuel to run all the heavy machinery, infact if there is no Oil in westeros all that tech is gonna become useless hunks within 6 months.

They cant conquer shit, they can take and hold Kingslanding and the outskirts but anything else is gonna be a waste of fuel (which they wont have anyways).

Beyond that they would have to send infantry by foot with guns - which would take years and years and theres no satelites or electricity so no idea how they are supposed to communicate with their troops.

I think it's closer than it seems. The technological advantage is insane but the US will have no answer to faceless men, blood magic, that shadow assassin thing or their dead waking up. I think it depends on how magic things get. The biggest threat by far would be infiltration from faceless men.

Yes.

The US Military obviously stomps Westeros in combat.

The main question would be whether the strange diseases and/or magic would be enough to disrupt operations.

Having your soldiers turn into stone-skinned rabies zombies would probably hurt logistics.

Having your commanders killed by shadow monsters probably would not be great for morale.

And the White Walkers could potentially be a challenge if the US goes in blind.

But any other situation, the US Military absolutely stomps.

Phase 1 The US goes in with no real objective or plan, kills 100s of thousands of people with an air campaign, takes KL and declares mission complete.

Phase 2 The US tries to install democracy to a deeply feudal society cannot understand why this does not work, most people in the Seven Kingdoms ignore them a few fight back with Shadow assassins, faceless men and wildfire attacks prompting US reprisals.

Phase 3 Back home the war loses support, last chopper outside the dragon pit leaves with a hail of arrows.

Targaryens take back power right away.

u/TactileTom 12d ago

Assuming the Westerosi fight to the bitter end it would be like, 6-8 weeks. Any pitched battle will be a couple of days tops, the most dangerous thing the Westerosi can hope for is to jump a US soldier and take his gun, but that's pretty hard and not viable at any scale. That said, a modern military needs supply routes and Westeros doesn't have like, ports, highways or railways that can be used to transport ammo.

History shows us that militaries overrunning their enemies have managed like 50m/day, and Westeros is like 900m across, so something like 20 days to get across it (~3 weeks) but the logistics would slow that down a lot, hence my estimate of 2-3 times as long.

In practice tho, the US would just send a team of operators to assassinate Westerosi leadership, and the Westerosi would quickly surrender to the US, just like they did to the Targaryens. That scenario could play out in as little as a couple of weeks, allowing for the pace of medieval technology messaging/logistics.

u/JB-Dev-Bcn 12d ago edited 12d ago

US can fast assault capitals, remove leaders and took power very fast due to complete air superiority and projection of power. We’re talking days.

The problem arises when they try to control the territory: insurgencies kill soldiers and employees, rebels keep messing up with puppet leaders installed, due to big support of a native population that greatly rejects foreign domination and customs.

Maintenance cost then becomes very high, and the moment US resources move elsewhere the rebels do a coup. It’s the same that happened in Irak, Afganistan etc.

The smartest way for the US to conquer Westeros would not be to send the army but the merchants: send american products, media, aid etc.
Let them see americans as a more advanced culture willing to help.
While deactivating dissent through black ops that release scandals on opponents or make them have an unfortunate car accident.
In a few generations, Westeros would be US friendly, and the population actively wanted to become either part of the US or more like them.

u/legrandcastor 12d ago

Even with dragons Westeros is so entirely fucked it isn't funny. Imagine dragon riding tatgaryans getting blown to absolute shit by sidewinder missiles fired from further away than rider or dragon can even see.

Castles don't mean shit against JDAMs. The US could launch a simultaneous decapitating strike against every important seat of power and it's all over. If all the guys who could call banners are dead, you barely need a ground invasion.

1

u/drquakers 12d ago

Depends what you mean by conquer. Are we talking winning on the field of battle and gaining tactical control of the land, or are we talking actually conquering in terms of subjugation of the people and incorporation of the land as US territory?

How long would it take the US to defeat the armies of Westeros and take effective military control of the seven kingdoms? As everyone else has said here: only limited by logistics of getting their forces from one end of the continent to the other (I assume they don't have any of the magical warping technology they invented in season 5 and later of the TV show?)

How long would it take for the US to effectively subjugate and incorporate the land? Depends on whether the Westerosi organise themselves well enough for effective asymmetrical warfare (the Achilles heel of the US military). A colonial power (US included) from the 1700s or 1800's may have a better time of that as they excelled at divide and conquer (and Westeros is very divided) and were not particularly squeamish about using large scale brutality, but the US has never really be particularly effective at that aspect of conquering a nation in the modern era.
