What would be the best modern weapon system for taking out a space marine...

land mines.

armor is directional. if you look at marine armor, they get almost no save from below...

>They have Plasma and melta weapons and no doubt have the accuracy needed to nail a strafing chopper with them
>Each Hellfire Missile weighs 47 kilograms (104 lb), including the 9 kilograms (20 lb) warhead, and has a range of 8,000 metres (26,000 ft).
>26,000 ft
>five miles
Sure thing my man.

...the fuck? You know tanks can track other vehicles at top speed, right? A tank can hit a car speeding along at 100 miles an hour.

REMINDER that Black Library wrote a story (Call of the Lion) where a group of Dark Angels knock down a strawman 21st century planet. They ignore 50cal rounds, absorb tank shots, punch said tanks in half, and teleport terminators into the UN to kill everyone before orbital bombarding the place.

...

Those giant boots of theirs redirect explosions like the sloped undersides of MRAPs

The autocannons common to IFV's are probably more what you're looking for.

youtu.be/X3MX_q12sqg?t=1m20s

Re-purposing something like an M163 could also be the way to go.

>A STRAFING chopper
>the same thing as firing hellfires at maximum range
Great, you launched 8 hellfires and killed 8 space marines. have fun flying within bolter range to do any more damage.

>A tank can hit a car speeding along at 100 miles an hour.

Sure, while it's traveling down a highway in a relativaly straight path. Not a 100mph man sized target zigging and zagging and jumping all over the place.

REMINDER that half of Black Library writers know about as much about military technology as a 14 year old CoD player

...

And a bunch of fat neckbeards on the internet definitely know more than they do.

Marines don't run 100mph while doing all that. Or even close to that. They've not consistently been shown to be much faster than a normal person.

>Strafing
>Helicopter
If you're actively evading ground targets in a helo, you're already dead beyond measuring.

Considering an Autocannon in 40k only has AP:4 and Space Merhens have AP:3, I fancy my chances more with HEAT rockets.

exactly, now here's my thirty page dissertation on why marines suck and 40k is dumb

Yeah but muh Heavy 2

>this statement is more likely to be correct that the Black Library Authors one....

If a space marine gets hit with a supersonic shell the size of an extra-large big gulp, they're going to get incapacitated.

>40kids

>This thread

Soo, you still need almost entire arsenal of your army to destroy a lone marine?
That also assume that said marine only standing there as target practice.

Holy shit, a puny guardsmen that was competent enought to use his surroundings can take him out with a portable missile launchers for god sake.

I could bring my Heavy 15 Str 1 AP - BB minigun and kill 41st millennium super soldiers with it, technically.

No but you see we can ONLY take the most extreme of marine stories of canon, the ones where marines run so fast that people shit themselves to death being unable to comprehend it! We can't take any of the stories that may make marines look bad as canon.

Like how Genestealers eat marines alive in spacehulk but an old Imperial Priest managed to take down a hive of them with Feudal World cavalry and crossbowmen.

For those too lazy to read. Glorious BRRRRRRTTTTT went through >3in of steel at ~80 degrees

SM don't use steel armor though

Just summarizing the report. its up to other neckbeards to come to a conclusion.

>but you see we can ONLY take the most extreme of marine stories of canon

Then even our most advance railguns still can't take him out because he just sneak around, turn the environment into his advantage, throw a melta bom to your crew and walk away into the sunset.

Or he can just pray to the emperor when wounded, get trought a weird warp-induced dream sequence, get ressurected, and fuck you harder.

Or just came to your tank and simply slap it to death with a wet fish.

Glorious BRRRRRT can't kill actual battletanks except from the rear.

Modern Tanks no but older tanks it could. As showed.

Nope. They'll be fine. Because Space Marines are magic.

And only magic can defeat magic.

And above

Your Composite armor are only thick on the front side, but get halved on its top and rear, because nobody want it to be another Maus. And thats also only against HEAT in first few hits due to ceramics plating, against AP? Not a chance.

Plasma and melta weapons are both fairly short ranged in comparison to anything required to hit a helicopter.

Real attack choppers fly by their targets fast and are fairly far away.

Depends if you buy .50 brownings being heavy stubbers or not but any armored vehicle weaponry should be able to penetrate normal power armor fine. Its tough but its not that tough.

Also artillery is massively underrated for what it can do to armored targets.

>100mph zig zag

Then why don't they do that in fluff?

Wait they don't, they can sprint at or above olympic sprinter speeds in full armor.

A-10 can't pen top armor of modern MBTs, and even if it could it would need a completely controlled airspace to pull it off.

A glorified minigun killed a heresy era marine in the first novel, the BRRRRTTT would probably kill, if it actually hits.

>That also assume that said marine only standing there as target practice.
thats how marines normally fight so thats a fair asumption to make.

In one single hit

In salvo+ AtG? Yes it can

Its not that effective anymore because tanks always accompanied by portable SAMs and AAs, which her slow speed can get her killed.

Codex Astartes and illiteration in Kill Team are dissagree with you.

a stick
dorito dust
dog

used separately or as a combo, equally effective

...

>killing 8 space marines
>with something that's basically second or third line PDF equipment

Fucking sure bro, you just scored a 1500000% modifier on investment made versus reward gained.

I'd make that trade any fucking day.

a modern military would pretty much dominate any 40k army. what you have to realize, OP, is that the 40k armies are literally retarded. the IOM have very good material science but everything else they have is WWII level technology. their tactics are even worse, WWI level.

a single bomber could load up with CBU 105 cluster bombs, and kill hundreds or thousands of marines in a single run.

youtube.com/watch?v=CY9gojFu-_U

there's not kill like overkill

Every time I see this I wonder why it's not already a thing in 40k. Put a servitor brain in it, load it with some cheap atomics or plasma bombs or what the fuck ever and let fly.

It's exactly the kind of brutality the setting loves.

Not to mention trying to melta anything further than five feet.

>It's exactly the kind of brutality the setting loves.
>the engine is not shielded and irradiates everything this thing flies over
>this is considered a merit

Precisely. It cannot miss its target, and any friendly forces it might fly over were clearly in the wrong place at the wrong time, and as such were not obeying the will of the Divine Emperor.

And therefore were probably on the road to Chaos anyway. No loss.

And in another black library book, some marines get pulled down and killed by unarmed mob of civvies.

The Leman Russ is even slower than most modern tanks and its one of the most cost-effective ways to kill a Space Marine. A helicopter would be too exposed. Tank is best.

>too exposed
Modern helicopters can fire missiles from behind cover with no issues at all.

BMP-2 or 3, Stryker... any vehicle with 30mm+ rapid-fire cannon and AP shots is gonna tear a Space Marine a new Progenoid.

Considering their armor is better than pretty much any cover save, they don't really need to bother in their tactics.

Demonically enhanced muscle mutant peasants whose pitchforks have been demonically blessed to be demonically effective anti armour weapons and who come in demonically coordinated swarms aren't """"""unarmed civvies"""""" (goddamn Ben Counter).

I mean if you could remember the title at least I'd give a shit and go check but you probably can't even do that.

The Deathwatch has automated killships that they can launch to perform Exterminatus remotely. Think SLAM except it nukes a planet so hard life can never exist on it's surface again. With lasers. And plasma. And things.

That's basically the same thing as the good ol' flying crowbar, except bigger!

>>everything else they have is WWII technology
>>he thinks man portable directed energy weapons at squad level, flying tanks, space ships, orbital artillery, orbital deployment of troops via reusable missile, and energy shields, are WWII technology
>>he may be retarded

user, I...

Second soul drinkers book.

As a combo??

Jesus man that's a violation of Geneva II at minimum just by putting them in the same room...

A suicide bomber.
Just insult his primarch and challenge him to melee and he will no doubt oblige by closing to within chainsword distance.

could you be more specific with your claim?

like, I don't know, a quote?

have you ever had to prove something to another person before, or did mommy just believe you right away?

Genestealers are hugeass stupidly strong killer monsters from space who have psychically powered anti-armour hands.

Why does dying to the Alien on giga steroids make space marines bad?

It just proves that genestealers are scary shit, which they are.

>automated strategic decision making device

That's some heresy, son.

And yet, they use trench warfare and wasteful human-wave meatgrinder tactics. Employ literally cavalry with exploding spears. Slow Infantry support tanks bristling with limited-arc weapons. Starship weapons loaded by hundreds of people literally pulling ropes.

user's right, despite their technology the ground tactics are terrible. Shooting people inside missiles is also an insane idea, no matter how you slice it.

Depends on the opposition, the current regiment illustrated and often - the writer behind it.

The Imperium is huge.

Tactics vary from block formations to human wave, to trenches to armored blitz to combined arms to simultaneous orbital envelopment of the enemy with astartes dropping ontop of your most valuable strategic assets.

Also, trenches are still useful. Look up conflict in Ukraine right now. As for using wasteful human-wave meatgrinder tactics, look up ISIS. Now swap exploding spear cavalry with exploding truck, another tactic they use. Religious fanatics don't really care about waste of human lives.

Some of the black library novels say you can kill a marine with a sharp stick and a bunch of children.

So a marine in Africa with Child Soldiers would auto kill a marine

Look at it this way. A guardsmen is less expensive than a gun better than lasgun. Really fucking cheaper.

>durr dimestore pulp novel writers surely know more than a group of the most autistic people imagineable
Don't make excuses for shitty writing
I guarantee that there are a significant number of people on Veeky Forums who know far more about military matters than anyone at BL, have you seen /hwg/? Those niggers know their stuff

That's what the missiles are for
But yes I agree, the A-10 is basically only useful against second-rate militaries with no air defense, eg; Iraq.
Sexy as hell though

>the ground tactics are terrible
In cases where they're fighting equivalent enemies, like human chaos cultists using small arms, they generally use pretty standard modern infantry tactics, at least in the Gaunt's Ghosts novels.
The thing with 40k is that its setting is so massive and varied that you can see anything from utter incompetence leading to millions of dead troops to flawless leadership leading to victory over insurmountable odds.
Which is why the premise of 40k army vs modern Earth army is retarded, it's far too broad a question.

As a cold war enthusiat and former soldier, I do hope so.

Even if you reprogrammed the bomblets so that they'd recognize a marine, I don't think they'd be as stupid as to clutter in such that way that you can wipe out entire chapters in a single pass, considering that the setting is quite artillery-heavy.

My bet is on inertial guidance with some basic autonomous terminal guidance system.

>and warthogs have the stopping power required to punch through power armor

HAHAHAHAHAHAHAHAHAHAHAHAHAHA

HA-HA

Warthog is 30mm Revolver cannon and even modern 40mm Autocannons are no match for 40k ones.
Astartes can take a full frontal hit from an Abrams battle cannon and be concussed and thrown back a few feet.

Also have fun with your GAU-Avenger BS 3/ 24"/S:6/AP:5/D6 Heavy, Jamming (if you roll a 1 to hit you can't fire next turn)

Disregarding the fact that most authors will use trench warfare and wasteful human-wave meatgrinder tactic because they know jack shit about RL tactics, this is a setting where axe-welding barbarians and cybered eletronic warfare teams can fight alongside. Don't reduce it to HURR DURR GRIMDARK.

A solution for defeating the Imperium of Man Space Marine, brought to you by Dahir Insaat.

Page 50.
"Squad Salk, report in!" Voxed Salk hurriedly to the Marines that had stayed behind to cover his assault. 'Aean, Hortis, Dryan!"

The only reply was broken fragments of speech cut up by static. Whichever of them was still alive was swamped by the masses of the crowd so heavily that his vox equipment had been damage. Since the receiver was implanted in the ear and the transmitter in the throat, that meant a fractured skull at least. It was no way for three good marines, pulled down by a baying half-mad mass of dying civilians.

>GAU 8
>jamming
It's a motor driven gatling gun. The basic technology has been in use since the mid 19th century

Then he killed 8 times as many space Marines as OP asked about.
>...would kill a space marine
Singular. Hellfire missiles would apparently do the trick.

That statline actually has a reasonably decent chance to kill a Marine.

Wounds on 2+, even if they get the armour save that's got a very reasonable chance of killing a few marines.

Stairs

We've already established 40k editors and authors can't into military technology. Fuck, they can't even agree on 40k's power level from book to book.

>Even if you reprogrammed the bomblets so that they'd recognize a marin
no changes are nesessary, the skeets identify targets through IR sensors.

Shaped charges and the effect on anti-armor they had aren't really a thing in 40k, and for good reason - they'd break the point balance for special weapons.

In 40k, it takes a power weapon or plasma gun to reliably blow through powered armor, and this gives a fluff reason for why elite troops live so long to become so badass, special weapons that can one-shot them are rare.

40k uses WW2 tactics with souped up numbers. Occasionally special units use tactics that are shifted forward or backward a few decades for extra scifi feel or grimdark, but WW2 is the baseline.

The bolter for example uses a (rocket-boosted) APEX warhead - the pinnacle of WW2 armor piercing technology.

Shaped charges are what replaced this in the 1950s, because IRL humans spam broken strats like there is no tomorrow.

On impact, or by special fuse, these use explosives to forge a solid metal jet moving at massively hypersonic velocities far faster than any railgun - about Mach 25. At this speed, hardness becomes physically irrelevant as materials flow like liquids.

I'd say that a shaped charge in an ordinary HEDP 40mm grenade will punch through 40k power armor reliably, but not necessarily one-shot an SM thanks to redundant organs, etc.

A RPG-7 built in the 1950s, though, or any bigger or more modern rocket, is going to leave plate-sized exit wounds.

Humans confirmed for WAACfags.

this isn't necessarily true, reactive armor and deformed projectiles are a thing. also, the armor isn't a flat plate and deflection is a real possibility.

For when you need to wipe out a chapter of SMs

>The missile, when fired in a swarm (group of 4–8) has a unique guidance mode. One of the weapons climbs to a higher altitude and designates targets while the others attack. The missile responsible for target designation climbs in short pop-ups, so as to be harder to intercept. The missiles are linked by data connections, forming a network. If the designating missile is destroyed the next missile will rise to assume its purpose. Missiles are able to differentiate targets, detect groups and prioritize targets automatically using information gathered during flight and types of ships and battle formations pre-programmed in an onboard computer. They will attack targets in order of priority, highest to lowest: after destroying the first target, any remaining missiles will attack the next prioritized target.

modern AT weapons would completely ruin marines.
javalins
recoiless rifles
tows
hellfires

marines would be so fucked.
so so fucked.

Space Marines have also been killed by sticks and all sorts of things.
