Next, range. Marines have it. Romans won't even come close to that with their Javelins and their arrows aren't going to match it either.

Never mind the Marine Sniper that comes with the group to pick off Romans one by one before they know what's happening.

Never we have the Humvees. 100mph! 100 points for every Roman! That's right! Why even waste the ammo? You can plow right through them! Nevermind the Bulldozers that also have.

Then lets add in modern weaponry! Grenades/rocket launchers! AOE \o/

the Marines would have it. Nevermind the helicopters, that even if it didn't frieghten the Roman's would just make short work of them. Run out of ammo? Bet they could give a few Roman's some haircuts before they knew what was happening.

It's just not a fair fight. It just sounds like the Romans stand a chance, but really they don't. And there's plenty of ways for them to conserve gas/energy to make sure they win it, and it's silly to think they wouldn't if needed.
Brand covers it very well. Do you guys realize that the GAU-19 mounted on a Hummer can fire up to 2,000 .50 cal rounds per min? That bulled will punch all the way to the back ranks of a roman line.

Which means with the way the Romans line up 1 sniper shooting a .50 cal rifle could kill multiple soldiers in a single shot. There is a good reason we no longer line up in combat.

Have you guys considered the damage an RPG would do to a group of soldiers attempting to do a shield turtle? It would be very bad.

I suggest watching Locked and Loaded on the History Channel. I am not sure how many of you guys the devastation modern weapons can dish out unless you have seen it first hand. As a paramedic I have seen the damage non-military ordnance can do to the human body, and it only gets worse.

Also, a flack vest will stop just about anything the legions used short of siege engines.

No... but one of their common strategies was to have shields up with pole arms on one side stick out and then when the other side charged they ran right into the polearms...

The whole march forward till your face to face thing was the western version of Samurai honor. Basically, instead of being "barbaric" they constructed all these rules of war and it got to a point that is more about the show and rules than it was about winning.

Back in Roman times they marched in lines and such but it was only to a point and when the phalanx strategy was likely to fail they adapted.

Roman archers could shoot between 100 and 300 yards... Greeks were said to have an effective range of between 64 and 600 meters... so I think the Romans could get a bit further than 300 yards honestly.
http://answers.yahoo.com/question/in...7175754AAJQ2v4

M16 has an effective firing range of 500-800 meters.

So Romans have half to 1/8 the effective range.

Roman Ballistas had much higher range but was most effective at 500 yards


The fact is that snipers and guns have limited ammo and even if you hit all the targets with your spread fire you're not going to being able to pick off 50,000 men before they reach their effective range which will surely kill you or severely damage your gear/vehicles... and even if you do you're not going to do it 50+ times even if you are perfect shots.

Romans would likely take out a Humvee fairly easily used in that way...

Quote:

Ballistas, trebuchets, catapults, greek fire, etc, etc, etc... they could easily be used to counter much of current war fare's weapons and again the marines are fighting with gear that is designed for bullets, not rocks, arrows, traps, whatever. And their fighting styles are very much for taking on those opponents too... when you take that into account the Romans have the advantage of supply, experience, defense, and numbers, while the Marines more or less have only modern tech on their side.


Could the Marines win in an extended fight? Possibly. It's a matter of how well they adapt, how quickly they could establish a base, could they get food, could they resupply, would they pick up on the Roman warfare... and can they do it before their numbers are such that they could do it and before marines start giving up or finding an easier way out.

Also it is a matter of what their goals are... if it's just to kill all roman soldiers then they aren't going to win. If it's to destroy the country... that'd be a quick afternoon... if it were to take over the country and maintain control THAT would be where it gets interesting.

.
This could be quite effective, especially when targeting leadership and ranged siege weapon workers that do not understand that their clearly marked armor, and in some cases, formal positioning, will get them wiped out pretty quickly. The troops may be well trained, but there will be coordination problems with the leadership down.

Both sides get AoE, right? catapults and the like on Roman side, grenades, mortars and such on Marine side?

One thing to consider, when saying the Romans can rush the Marine and overwhelm them, is the bodies. There will be a lot of corpses stacking, littering the field. These, in such quantity will create barriers to any organized advance, extending the carnage. Initial carnage will be heavy due to the interlocking shield tactics, which are just begging to be mowed down.

That brings me to the American Civil War. Wasn't this exactly the problem in the Civil War? Modern weapons with old formation tactics. Heavy carnage. The problem there was that both sides had the weapons and the old tactics.

Someone pointed out the Zulu war, another good example. The Battle of Rorke's Drift, as depicted in the movie Zulu, showed the English concerns to be their limited ammo supply. I'm guessing Marines of 130 years later would have that as their one concern when facing 250,000

The Romans could fairly easily and safely confine the Marines by surrounding them and waiting in cover. If the Marines plan to eat, they would have to give up their position and their fortification and move within range of the Roman's where they will not stand a chance.

If the Marines had a limitless ammo supply or if the Romans were going to be intimidated by the technology and bow down, this thread and this conversation would be pointless. I have to assume those two variables are false.

If a single marine fell, that would mean a roman packing a firearm, and I wouldn't be surprised to see a legionarie wielding it better than any marine alive.

Failing all that, there's always poison, and that was by far their greatest weapon.

wow, that's so fundamentally wrong that it's staggering. first, the Romans were phenomenal COMPARED to current warfare techniques of the time. the range of modern firearms completely negates any tactics they could call upon, there was nothing in their world that had that kind of range. and their numbers WERE inexhaustible, if you counted the whole of the Roman empires forces.... which, by necessity, where spread throughout the empire, leaving less then you would assume in any one area, unless that area was under immediate contention. and catching on to "tactics" using technology they couldn't conceive of is kinda stretching it, especially in a time where "magic" was readily accepted. a small force of Marines could quite easily cause enough panic and mayhem to get the Romans to retreat, do that a couple of times and they would quite simply cede the area and leave. and the odds of a legionnaire with a firearm killing any marine over say... himself or other Romans is quite honestly ridiculous. lets not forget, Attila the Hun ran an extortion racket on the eastern Roman empire for many many years, as they couldn't beat horse mounted archers, too mobile, with too much range. so lightly encumbered marines with firearms and explosives would destroy them wholesale.


Oh yeah, that was the time that girl got her whatchamacallit stuck in that guys dooblickitz and then what his name did that thing with the lizards and it cleared right up.

Exactly what I was thinking, especially in the initial encounters, where the Romans would have no idea what they were up against. They'd have a several hundred/(thousand??) yard gap to cover before they would be close enough to use their own weaponry.. That entire spread would be littered with dead soldiers, making the march slow and cumbersome.. All the while getting blown apart by bullet fire.. Their armor would be worthless, and actually slow them down (Though, the Romans would likely catch on to that and go in more lightly armored after a few encounters)

Plus I'm no military buff, but couldn't the marines kind of "Run and Gun"? Where as I'm pretty sure Roman archers had to remain pretty stationary while aiming and firing a bow.

The Roman position did not hold up well in battles of mobility, a battle the Marines definitely bring to the front.

(As mentioned above, against Atilia)

If the Marines stay in one place, sure.

I was assuming that they'd start moving immediately and roll some tanks down the streets in Rome within a week.

I'm sorry, I just don't see how the Romans can take out a tank, especially one deployed with an infantry screen.

I won't assume that the Romans will be cowed, and I won't assume infinite ammo. I will assume that they're bringing roughly fifty tons of ammunition with them, though.

So not a chance against modern weapon ranges. Got it. I think we agree.

I beg to differ. Factor in XM25, mortars, helos, heavy machine guns... and the 440,000 rounds the ground troops are carrying as standard kit (ignoring any resupply), and yeah... Romans aren't going to close any distance. At all. Roman morale will break long, long, looonnnggg before any chance of their wonderful ballista, catapults, and scary arrows get in any sort of effective range.

Rorke's Drift certainly had ammo issues... but considering that was, what 100 versus ~3,500 it shows the advantage of technology nicely. And when you look at what Smersh linked for Ulundi... well, add 100+ years to the tech gap.

Not to mention a conservative ammo total has an MEU carrying well over 250k rounds, just for the infantry rifles in the man carried supplies.

Honestly. If you limit it to hand-to-hand, yeah. The Romans would likely win eventually.

If you're talking "give the Marines their rifles"?

THEN things get more dicey. Now the Roman shields might or might not be adequate protection against 5.56 and 7.62 mm rounds.

Now, grenades (thrown or launched)? The a phalanx attack formation isn't going to do the Romans ANY good there.

Helicopters? Have you SEEN the kind of damage a group of SuperCobras can do? Hellfires? Sidewinders? A FRIGGIN' 20mm GATLING GUN!

Now I refer to Marines as "cannon fodder". But in this situation, they'd win. Plain and simple. Only a ridiculous tactical blunder would make it otherwise.

Remember the plates in a vest are designed to spread out the force of bullets. Stuff moving at high velocity and with a very small impact area.

Honestly I'm not certain what'd happen if you whacked it with the edge of a sword. You'd probably, eventually, snap the plate. And you'd still have a load of blunt force trauma translating through the armor since it's not really designed to disperse that sort of force around and away from the body.

You're thinking maximum effective range on a point-sized target. Yeah. That's roughly 550m with an M16.

Maximum effective range on an area (think vehicle sized) target is about 800m.

These both have everything to do with the shooter's ability to sight and hit a target and nothing to do with the actual lethality of the round.

Absolute maximum range (where the bullet is still traveling fast enough to kill a target ) is much greater.

So the Marines don't even particularly need to be aiming at anything. They simply set up a field of fire and pretty much anything walking into it is dead. Plain and simple.

Quote:

The problem is, the Romans are going to be dead WELL before they get a ballista towed into that range.

Actually, probably not. Hell, the hummer could probably just drive INTO the ranks and run people over without much fuss.

What does a hummer call a shield wall formation? Speed bump.

The thing is, a standard MEU has more than enough ordnance to annhihilate the entirety of the Roman legions several times over.

2200 Marines
4 M1A1 main battle tank
7 to 16 Light Armored Vehicle
15 Amphibious Assault Vehicle
6 155mm howitzer: M198 or M777
8 M252 81mm mortar
8 BGM-71 Tube Launched, Optically Tracked, Wire Guided (TOW) missile weapon system
8 FGM-148 Javelin anti-tank missile
4 to 6 AH-1W SuperCobra attack helicopters
3 UH-1N Twin Huey utility helicopter
12 CH-46E Sea Knight medium lift assault helicopter
4 CH-53E Super Stallion heavy lift assault helicopter
6 AV-8B Harrier jet
2 KC-130 Hercules re-fueler/transport aircraft
Note: usually maintained in the continental United States
2 Reverse Osmosis Water Purification Unit
1 LMT 3000 water purification unit
4 Tractor, Rubber Tire, Articulated Steering
2 TX51-19M Rough Terrain Forklift
3 D7 bulldozer
1 Medium Tactical Vehicle Replacement dump truck
4 Mk48 Vehicle System
7 500 gallon water containers
63 Humvee
30 Medium Tactical Vehicle Replacement trucks

If you can tell me that a force armed like this could NOT easily wipe out a sixth of a million men (armed with spears, short swords, and big shields), you'll at least get a laugh out of me.

Yeah, I can't really see the Romans coming out on top. Their best bet would be to hand over the keys of the empire quickly and hope to take out the Marines once they're drowning in the best booze and whores the Roman Empire has to offer.

Let's try to settle this with a little bit of "role play"

Helicopter is likely the largest vehicle going through right? so how much clearance would a helicopter need and how low to the ground could it be... that gives us a "portal size"

Does the portal make noise? where is it located? is it visible?

I would say that even if the portal doesn't make noise any machine coming through will make noise...

I would say if they could place the portal it would be slightly north of Medolanum on this map http://resourcesforhistoryteachers.w...ire_1_A.d..jpg


So... the portal opens the Marines start coming through... What happens?

Well the first this is likely some people would see what's going on and within a little bit of time a messenger would be sent to the closest Legion. That legion would like react and meet at Medolanum...

If i remember a legion can march like 30 miles in a day...

So at this point is a legion close enough to set up by the time the Marines are ready to do anything

How would the Romans and Marines act? Also would the Marines start off with the goal of taking over an holding or would they be peaceful at first and who would act first?

by coincidence, my gaming group was talking about how a set of WWII tanks would take out an M1 Abrams

the strat was dependent on the amount of ammunition the M1 could carry and amounted to: send tanks until it runs out of ammo...another tank blows out its engine, the last tank rams it repeatedly until it is out of operation

that was like 60 King Tigers vs 1 M1 Abrams

I doubt going back to things less mobile and efficient would help any

I'd expect that the hardest that the blade would be shoved (gladius designed and trained for stab, not slash) would be with less force than that of a modern bullet hit (but I am not a physicist, nor do I play one on TV).

the marines should be ready to do something the moment they're through the portal

with the various transport options, Marines can cover hundreds of miles in a day

by the time the MESSENGER reached the first legion, the marines would already be moving and have established positions

by the time the legion was started out their based operations, the marine helicopters would have seen the formations forming up and radioed it ahead

before they even saw the marines, the Roman column would likely be facing a pre-placed claymore ambush followed by distance mortaring

the first legion would take around about 10 minutes of work without any legionairre even seeing a hint of the enemy and with the marines mostly seeing them through binoculars


Really, though, someone has already referenced the Zulu wars.

If the British did it in the late 1800s against the Zulus, where the tech and strategy difference was far less pronounced, then yeah, the MEU would be fine

Ok would the marines establish the nearest city as a base or would they go directly to rome?

We're going to say, as was common practice there was a messenger that left from where ever the legion was to Rome and when the legion was getting it's butt kicked they'd send a messenger out to say what happened


I would guess that a second legion would start marching almost immediately as soon as the messenger got to Rome... And several messengers would be sent to gather the other legions which would all likely converge on either the 2nd or Rome.


also we're taking it from the position that the marines are just randomly hostile and not play any sort of game? They just intend to conquer and hold right?

Seriously, even if the vehicles only had enough fuel for a WEEK it would be enough to get the job done.

The Caesar and Senate fall within the first hour to air to ground bombardment from the Harriers.

Within a day aerial recon of the ENTIRE ROMAN EMPIRE has revealed where each legion is camped. Estimates have been made as to enemy striking strength and mobility. Plans have been made to nullify the numerical advantage - most likely by selective annihilation of enemy leadership. In other words launch a Hellfire into each legion's commander's tent.

At this point the war is over, really, before it even began. WIth the civilian government destroyed and presumably squabbling among who leads now and most military leadership eradicated any counter attack would certainly NOT involve the carefully amassed entire military force of the roman empire. Especially since destroying a few bridges and roads could delay legion reinforcements for months.

Pitched battle, open land - Marines will win, but sustain heavy losses (you can reload only so fast, and the concept of death was different to Legionaires than to modern man, insofar as sense of self is not as finely tuned and men of the Legions felt that it was their duty to follow orders and die)
Siege, Romans entrenched - Marines will break through defenses with some losses
Siege, Marines entrenched - Romans will starve the Marines into either making a break or preemptive strikes on Roman defensive emplacements
Pitched battle, broken field - Marines win handily. Tanks and humvees will survive where horse and chariot falter.

This is NOT a slam dunk. The fighting trim of a Legionaire places them on the same level as a Marine. The same training programs and the same PT, even similar amounts to carry on patrol.

Do not forget that Serpentines, Ballista, Catapults, Siege Towers, Boiling Pitch/Flaming Oil (something the Marines have no counterpart since the Geneva convention) and significantly superior numbers of superbly trained, if crudely equipped, soldiers makes this as dependent upon the ability of the Colonel as it does the fighting trim of the Marines.

The Marines would win, under most any circumstance. But, if one thinks that they're all going to survive with nothing but scratches, dysentery, and a profound sense of accomplishment, one would be gravely mistaken.

There is a REASON Roman military tactics are STILL taught in modern times.
