The problem for the Space Marines is we have the numbers like Orks but we stand off and blast things into little bits like the Tau.

[@CU17EN]

I've always thought this was an interesting problem/opportunity with the lore. I don't think it would be possible for 1000 space marines to take a planet. The planet we are on is enormous, find a mountain, and picture 100 space marines on it... what can they do really? This is why the Guard is so important. You need Space Marines turning pivotal battles, maybe striking key targets, but the Guard is going to do the heavy lifting. I'm not certain about the ability to target orbital stuff with nukes... doesn't seem too unfeasible though. If it were possible the Space Marines would have to deal with hundreds of launch sites, along with the nuke subs, which they are going to have some trouble dealing with. Decap strikes really wouldn't work with a modern military playing for keeps, because the command structure is going to be divested down to company and platoons. Let's say you get some CORPS commander(several star general)... doesn't really matter, because the colonels and lieutenant colonels are still bringing their guys to the fight, and they're tied into battle formations. You get them, and the companies are still coming... One bit that the Space Marines would have trouble with is logistics, you need to have enough ammo to keep fighting. They wouldn't have enough ammo to kill everyone. Modern militaries have entire battalions created for the purpose of bringing fuel and ammo. Air superiority would be pretty decisive, the Space Marine fighters may be able to win against say the 4th generation fighters, but the Space Marines don't have enough. So when the space marines start taking 500/2000 lb guided bombs (which have been used against helicopters in flight) they are also going to get wrecked. One further problem is technology. Human technology in 40K is advanced but also regressed. Leman Russ tanks are essentially WWII tanks with lascannons bolted on. Rhinos are not really anything special, and when that Abrams zings that depleted uranium round from 3 KM out, it's going to have a bad time. Space marine fighters will _likely_ have difficulty dealing with an F22. They may win, 10 v 1 against F16s, but when that spicy boy with no radar signature shows up, probably a different ballgame. In this scenario, the best chance the Space Marines have is with the space craft. A battle barge may be able to force capitulation just with bombardment, but that will rely on the inability to strike back with nukes. Anyway, fun vid, one of my favorite 40K/real world thought experiments.

[@censoredduetowrongthink]

Fun fact, the U.S. has smacked one of our own satellites in orbit with a missile just to show we can, we 100% can reach out and touch a battle barge. Probably wouldn't do much because muh void shield, but we can absolutely let them know they're in our AO

[@ElZilchoYo]

When the lore says a chapter conquered a planet, you need to read in the same was as Cortes conquered the Aztecs. Yes he did as the spearhead with a few hundred men, but also with 100,000 usually unmentioned native allies. The imperial guard holding positions and occupying and mopping up etc are not mentioned because the space marines take the glory when they assault the capital buildings and kill the governor. My point is that the lore is not being honest and just ignoring the IG following behind the marines in the same way our own history often does.

You are missing a few things though. Astartes are like special forces its is not just decap strikes against leadership but also against infrastructure and logistics. their sensors wouldn't even care about our thinking of stealth and submarines and Carriers would be orbitaled in moments. Silos would just be slag shaped holes in the ground and deep bunkers like Cheyenne just gone along with the mountain. If the US, China, Russia and Europe are totaled the world is effed regardless. Their marines would teleport and drop into important areas take out their targets and return just as fast to prepare for the next strike while the barge in space would take out communications and other important targets like entire airports and stockpiles. You could have a company moving to relocate only to never arrive because an Astartes squad spotted them and took a short detour to rip them apart with their bare hands. earth would surrender because if this was the early strike force we would be horrified what a large force like Imperial guard would do to us.

I just wanted to throw in my two cents here because I was a machine gunner in the marine corps and have a good bit of experience in small unit leadership and mission planning. I agree with the conclusion. 1000 simply isn’t enough. We have so many armor penetrating weapons specifically designed to shred through thick metal. Javelins, TOWs, SMAWs, LAWs, Carl Gs, mk-19s, M2s, the SASR and that’s just the stuff we carry on our backs. Naval gun fire, artillery, mortars, and the aircraft that we have would undoubtedly level 1000 dudes even if they were super human. The only thing I think they could do is teleport into strategic location and just pick off key leadership one group at a time but they could never conquer earth. If they did that.

I refuse to accept that modern Tank guns and anti-tank rockets wouldn’t do a number on space marines. You cannot tell me a 120mm APFSDS depleted uranium round coming out of an Abrams main gun wouldn’t punch through a marines power armor. If it somehow didn’t, if the armor is actually that hard, it would still cause massive internal damage, such as lethal concussions, just due to the shockwave. But I just don’t think that, based on how anti-tank weapons are written about in the heresy, Im pretty sure any modern anti-tank gun like an Abrams armor piercing round would punch a whole clean through the chest plate of marine. This is how marines are written in lots of lore, they are powerful, and completely invulnerable against small arms fire, frag, etc, but if human soldiers start lugging in massive Las emplacements, it’s an issue.

Like you said the Abrams and it's gun. Leopard, ifvs. Not sure how well the cannon on IFVs would do against them tho. Like you said, space marines basically wear miniature tank armour. -but our long range style of fitting would do major damage. They will certainly need an entire chapter to take our earth.

I think that a heavy tank shell could definitely take a space marine easily, humans are really, really good at killing, and while a Bolter is a fully automatic light rocket launcher, they have been fairly effective against power armor, a British challenger once took like 25 RPG hits, the heavy vehicles of the Astarte could be taken with missiles or just some Bombers. We also have the advantage of range, while marines like to engage in like a few 100 meters or even melee range, we have weapons that can hit from dozens of kilometers away (like the panzerhaubitze 2001) The only thing I can see them doing is bombardment, so if the human orbital strike would be effective, the space marines just lose, if the ship can survive then it depends on how much orbital bombardment the marines are willing to do.

A dozen or so well trained men could take out a space marine with booby traps & sticky bombs. 1000 marines wouldn’t stand a chance because you need 4 to pilot a tank.

[@ThatGuyOrby]

The only problem I see with this scenario (9:10-10:35) is that this heavily depends on a lot of things going perfectly for the Space Marines and depending on a very specific sort of response from the country they're going after. 1. Most armies don't really do the whole "charge and hope for the best" style fighting anymore (at least armies not from Russia) because the modern battlefield is about drowning the enemy in coordinated accurate artillery, missile, drones, and rocket fire while maneuvering with armored vehicles and mechanized infantry. 2. This depends on the country at play placing the utmost concern on the life of their leader over the security of their state. In dictatorships this is very likely. China or Russia could likely be taken out this way. However more democratic nations are far less likely to succumb to this tactic. The US in particular has a rather extensive line of succession in case of the President being captured or killed (Vice President, Speaker of the House, President Pro Temp of the Senate, followed by the entire Cabinet of Secretaries) so going for the head here doesn't really work because it's the Hydra effect at play. Cut off one head and two more take it's place. 3. Smoke grenades, at least non-thermal ones, don't fool/blind thermal imagers used by drones, tanks, aircraft, missile targeting systems, and other fire control systems of most modern weapons. And if they can be see they can most certainly be killed by any of these things. There are, however, more advanced Smoke Grenades in 40K lore called "Blind Grenades" that do spoof thermal imagers. They are however much more rare and expensive than the more common Smoke Grenades so it's a bit iffy how many of these a chapter would have on hand. Even in the cases of them being deployed most countries wouldn't feel a need to push an obscured foe rather just firing into the smoke from a distance 4. Adding on more to how certain countries fight, let's just keep running with the US for now because they're the big obvious one in this scenario, they heavily depend on combined arms maneuver warfare. There would be at no moment any time where Artillery, Mortars, MLRS (Multiple Launch Rocket Systems), Air-to-Surface Missiles, GPS guided bombs, ATGMs, Grenade Launchers, and Tank fire wouldn't be pounding their position from more or less every direction and most modern forces (unless they're defending or trying to take important territory) won't let them be fixed in place and engaged, they'll back off and maneuver while continuing to lay on the hate. 5. Tanks would be the bane of the standard Astartes and Terminators. It is pretty easy to estimate how protective the armor of a standard Astartes is and by extension infer on the Terminators. Using most official art of what a Space Marine's armor cross section looks like the thicknesses come out to about: Helmet: 25-38mm (1-1.5in) Pauldrons: 64mm (2.5in) Breast Plate: 50mm (2 in) Arms: 25-38mm (1-1.5in) Legs: 25-38mm (1-1.5in) Ceramite's strength is rather vague for narrative reasons but in general a common rule of thumb I've seen is two times its thickness in steel. So double all the values above for protection values. That means an Astartes has the following practical protection: Helmet: 50-76mm (2-3in) Pauldrons: 128mm (5in) Breastplate: 100mm (4in) Arms: 50-76mm (2-3in) Legs: 50-76mm (2-3in) This is some serious protection by our modern standards. This is roughly equivalent to walking around with a WW2 era Heavy Tank's worth of armor protection. In fact it's pretty close to the likes of being equivalent to just walking around in a Tiger 1 as a suit of armor. Serious protection against small arms fire but the amount of anti-tank weapons we have nowadays makes a mockery out of this. Infantry Fighting Vehicle mounted 25mm, 30mm, or even up to 57mm cannons would make mincemeat out of it. Vehicle mounted ATGMs would eat it for breakfast. Tank cannons would punch clean through a half dozen of them one after the other if they were lined up. The AT-4, which the US uses extensively, would pierce clean through. The Javelin would be overkill. A direct artillery shell might not penetrate the armor but the Astartes probably isn't surviving the force from it, or is at least going to be REALLY feeling it. The regular Astartes would be impervious to any standard small arms fire. Doesn't matter if it's 5.56, 7.62, .308, or even .50. Nothing is getting through that. The best .50 ammunition out there is rated for MAYBE 40mm but that's classified. Typical Astartes armor is estimated to weigh about 227kg (500lbs) but Terminator armor is estimated at four times the weight at about 907kg (2000lbs). One can reasonably assume then that it is close to four times the amount of material likely mostly in armor (but also some of that is obviously eaten up in more powerful motion assist servos and other misc things). Taking this at face value and slapping on a flat 4x to the values of the regular astartes armor we get: Helmet: 203-305mm (8-12in) Pauldrons: 508mm (20in) Breastplate: 406mm (16in) Arms: 203-305mm (8-12in) Legs: 203-305mm (8-12in) This is more or less equivalent to a 1960-1970s era Main Battle Tank. Absolutely obscenely well armored. It will basically eat any hand held anti-tank weapon for breakfast save for a Javelin or NLAW at it's strong points and generally speaking when using a handheld anti-tank weapon you're not aiming for weak spots (in this case the arms, legs, head) you just aim dead center and pray to hit. So while something like an AT-4 would probably still penetrate the arms, legs, and helmet a hit there would be unlikely. It would be immune to autocannon caliber AP rounds. Unfortunately this protection will not save them from: The Javelin, NLAW, any modern Tank Shell (600-800mm of penetration with almost 100% first shot accuracy on the move at a range of greater than 4km), ATGMs (ground or air based), direct hits from high caliber artillery or rocket systems, cruise missiles, JDAM smart bombs, etc. But the biggest problem for the Terminators and regular Astartes is that modern tanks are FAST. 72km/h+ (45-50mph+) fast. Regular Astartes, if statements are to be believed, can sprint this fast...but the problem is that this is a speed that a Main Battle Tank can easily track and hit on the move and while the tank will almost certainly hit and kill on the first shot while maneuvering I don't think there's anywhere frontally that a Bolter is actually going to fatally penetrate a tank (keep in mind that bolters heavily struggle with Terminators and if they'd struggle with the values listed above they are not defeating modern MBT armor because those values are below the known values of tanks that entered service in the 1970s. A bare bone T-72 has more armor than that). Maybe the Astartes could shoot the track off but what are the chances they're going to make that shot at 3-4km and then proceed to avoid every single kill shot a tank will throw at them every five or so seconds in the entire time it tanks to close the gap?

Short Answer: No, No 1000 Marines can't conquer earth Long Answer: Given the scenario you described, with Astartes bunkering down in one place, is inviting them to just be drowned with Hypersonic Missles, Artillery and all manners of High Explosive weapons, you forget, melee would only help if the Marines get close, which would of been filmed and shown when the Chapter Master and his Honour Guard tore their way through an ambush whilst taking minimal casualties from normal weapons, but taking severe losses to Heavy weapons and rockets, at the same Earths united Military would use the time old tradition of blow it apart from 10 miles away, even more so given the fact Marines will shread up close. Whilst yes 800 Marines are extremely scary, and our hand held guns would be next to useless, but our armour and air dominance, as well as overall better understanding of combined arms warfare, the Marines would cop a massive fucking L against all of the world.

Just a friendly reminder to some people who forgot that the US exists and we don't fight with just rifles. There are a vast many, MANY vehicle mounted weapons, ranging from 50. Cal to 20mm to the 30mm, to the 40mm, and for some absurd reason, we are even making 50mm auto cannons. These are placed on a myriad of vehicles. The most common is the 30mm, aside from the 50cal. The Apache has a 30mm chain gun. The Bradleys have a 30mm bushmaster. Much faster rate of fire. There are plans to upgrade those to 50mm, again, because 'Murica. The design of these rounds are usually armor piercing high explosive. Some have a bit more omph in the explosive department for anti personnel purposes, and others are more for piercing armor, such as the rounds fired from the GAU Avenger from the A-10 Warthog that uses depleted Uranium (Uranium self sharpens as it penetrates metal, does not deform like most other metals would, makes it excelent for turning tanks and bunkers into very large cheese graters. The main concern from use is the cancer risks to areas). To put it lightly, our lineup of 30mm based weapons would shred space marines. We have a lot of 30mm, fired from a myriad of wheeled vehicles, tracked vehicles, helicopters, jets, and boats. The US LOVES 30mm. That and 50.cal. People have to remember that the people who made the 40k universe did so DECADES ago, and they are not military experts. They went with things that sound cool, but are just that, cool sounding. Not practical. We also have to, realistically, assume that their laws of physics would have to obey ours. Trust me, if laws of physics were different, the US would likely be a lot different military-wise too. I love the 40k universe. It's very cool. But again, it is far from the best it could be realistically. The creators had/have a very outdated and poor understanding of military technology. Again, cool factor over realism. And the US has a lot of very real and cool stuff these days. Newer ATGMS, MANPAD munitions, artilery has some new upgrades, and we even upgrade the old stuff using new stuff. JDAMs are not bombs themselves as people often mistakenly think, but are upgrade kits for our stockpile of old bombs. The short of it is: bombs can be pre-programmed to land with a few feet of a GPS coordinate before leaving the air field and even edited while in the air. Makes saturation bombing a thing of the past, and you can drop from way higher in the air and only where exactly needed. And due to the inconsistencies of the power scaling, even being generous to our favorite space marines may not be enough to spare them their fate. TLDR The United States is scary and would probably spend more money if it knew Space Marines were real and a threat. It did so to match every claim made by our rivals during the Cold War and even to this day, even if those threats ended up being just a farce. That, and they LOVE 30mm.

Especially since they have to cram in cooling systems, armor plating, and all other sorts of crap when the largest mechs are only around 10 meters in size, give or take.

⁠​⁠@@fuchsmichael93well they would have more than one named character per Chapter: Chapter Master, Librarian, Chief Librarian, Master of the Fleet, Master of the Forge, Chief Apothecaries, Master of Sanctity, Venerable Dreadnoughts, Captains, etc the list could go on. I’d say we’re pretty screwed from that.

Their main advantage is space superiority so they might be able to flip the attrition war to their side by keeping up the orbital bombardment, which does damage more infrastructure but after losing >200 marines would seem the surest way to do it

And then all it takes is 1 cheeky green boi to doom the whole planet.

My problem with 40k is that it wouldn't be the whole Chapter, but a squad at best. It is very unreasonable to expect the whole chapter to do anything except in the most dire of circumstances like a Black Crusade or the war for Armageddon. With a million worlds in the Imperium and at least as many hostile worlds to fight over there is less than one Space Marine for every planet.

a video idea: how would roboute guilliman run earth? or how would roboute guilliman be as the president of the US / the leader of a major country?

Conquer, maybe not. Annihilate, Yes. I think if they took out all the satellite were shot down and maybe a few nuclear powerplants, then strategic orbital bombardment would create enough chaos that some consider out right surrender.

Yes

@@tobivsmaximvs7401 That is how you lose half a marine chapter. You goddamn numbskull that would be walking into certain death. With F-22s, F-35s PATRIOTs and THAAD.
