very much so. but the chemical application isn't something i see happening during the battle--it's something you'd have to do ahead of time. i'm sure Cray74 can come up with some ideas.

Does anyone know what the interaction of thermite and modern tank armor is like? Anhydrous hydrazine?

Okay.

How about immobilizing the beastie?

Aren't there Elemental spells that can change the structure of earth?

That is, turn solid ground into mud or something?

As powerful as MBTs are, their size and weight are their weakest points.

Put one in a situation where it can't maneuver, and you've won at least half the battle.

A good example of this would be the experimental World War II German superheavy tank, code-named "Mouse".

Here's a link: Lone Sentry: The German Mouse heavy tank "Maus"

The beastie was so heavy that it would sink into ground that was the slightest bit wet. Also, the vibrations caused by its passage shattered cobblestones.

And even with two 1,200-horsepower engines, its maximum cross-country speed was 12 MPH (19.3 KPH).

Aftermarket as a rigger I'd definately be adding amphibious operations package to the thing. Hell, it already has the lifesupport system, engine sealing and crew sealing isn't going to add that much. Besides, I don't have my books right now, but its off-road handling (muddy etc) is what? 4? 5? Not that hard for a rigger which firstly drops it be -3 (only vcr 3 riggers would be allowed to drive the thing, 7million off the factory and all) so now its a 2 or 3, and then they can dump as much dice as they want into it, only needed 1 success to succesfully keep going through it.

The steel parts slowly, very slowly melt away, while the ceramic bits won't mind much. The AN-M14 TH3 incendiary grenade will only penetrate ½" RHS during the 40 seconds it burns, which basically means it will not penetrate any non-aluminum AFV's armor. It could possibly be used to inflict serious damage to some equipment on the vehicle, but that would not be a healthy thing to attempt in a combat zone.

Thermite will work wonders on some of the slightly older APCs with aluminum armor plates, however. I bet you could crack open an M113A3 with the AN-M14.

As for the Maus, well, some lessons were learnt from WW2. It is interesting to note how modern MBTs are lighter than King Tigers, provide up to 6 times as much protection as the Maus, and have several times the firepower (in terms of neutralization capability of enemy MBTs). Pitting WW2 tanks against modern ones, the fight would be very short and insanely one-sided. Pitting WW2 infantry against modern grunts, the latter would only have a slight edge -- mostly from communications.
Kagetenshi
If you were able to spread around very large quantities of the stuff, several kilograms worth, do you find it at all likely you could do meaningful damage? Several tens of kilograms?

~J
mfb
i don't think thermite burns hot enough to really do any damage to the ceramic armor. however, the crew inside will probably notice a sharp rise in temperature.
Austere Emancipator
You'd destroy the optics and would stand a good chance of ruining the weapons, if you could cover most of the turret and front hull. If the tank has stopped, you could probably immobilize it -- with a moving tank, I wouldn't count on it. Actually destroying the vehicle would probably take a huge pool of thermite to dunk the tank in.
Kagetenshi
How conductive, heat-wise, is the armor? I'm now wondering, similar to mfb's statement, if you could essentially force the crew out or raise the temperature above some of the internal equipment's maximum operating temperature, even if you didn't damage the actual structure of the tank meaningfully.

(Don't mind me, I'm just playing with ideas)

The ceramic bits, not at all. The steel, not very. You'd cripple the tank completely before the temperature inside rose to unbearable levels. With 2060s life support and concerns of flame/incendiary weapons, it wouldn't surprise me if SR MBTs included effective cooling systems in the life support system. Not to mention that covering the tank with thermite or similar weapons would fuse shut all exits.
Kagetenshi
Hm. Mobility kill plus fusing the exits. I like this plan. Then you'd just have to keep meaningful support away for a little over two days, which might be harder.

The problem is, how are you planning to apply the dozens of kilograms of thermite all over the quite hostile MBT?

No one has mentioned Nanites yet? Delivered by mortar or artillery similar to a gas attack on the vehicle. They could eat the sensors, armor, chemical seals, etc. The tank might complete one mission. But it would have to spend some time in the shop afterwards.

Don't attack the tank directly. Attack its support crew, fuel transports, and ammo carriers. Without them the tank can't function as a long term threat.

Isn't there a canonical Elemental spell called "Acid", "Acid Bomb", or something like that?

If so, what sort of acidic effects does it produce?

What I was thinking was that, if it were possible to select a particular kind of acid--specifically, aqua regia.

It's a combination of hydrochloric acid and nitric acid (the usual mixture is 3 or 4 parts hydrochloric acid to each part of nitric acid), originally used in the precious metal industry because it's one of the few chemical compounds that react with gold, silver, and platinum (and other members of the platinum family, such as rhodium and osmium)--the so-called "noble metals".

It's less corrosive when cold, but when heated, it gets really nasty (and the more it's heated, the faster it works)--we're talking a substance that, given enough time, could dissolve its way through stainless steel.

Just a thought.

Like all elemental manipulation spells, the secondary effects take effect only if you do reasonable damage with the spell. It's been said before, but it's worth saying again: you need a FORCE 41 MANIPULATION SPELL TO HAVE ANY EFFECT ON THIS THING. So no, Acid Bomb won't work well.

I'm willing to bet Aqua Regia, "used for hundreds of years in the jewelry industry," is nowhere near an appropriate anti-tank weapon, hot or not. "Given enough time" seems to be a real hinderance when talking about modern armored warfare. Stick to the naval guns and strategic missiles, I'd say.

Hunter A calls in fire support to shred an obnoxious tank. Said weapon does 50D AV. Weapon hits six thick walls on way to the tank reducing the power to 5D AV. Using your logic, since its a 50D AV weapon it would pierce the tank.
Ah, no. Because in that case the 50 never hot the tank. a 5 did. That makes the base power of the attack that hit the tank a 5. Please, please do not presume to tell me what "my logic" is, when you obviously don't have a solid grasp on it. I'll quote the book when I get home if someone hasn't done it by then.

When an explosive reflects off of surfaces that it can't penetrate the target gets hit with a much damage code. This is not staging. This is the power of the attack.

I paraphrased the book but the quote won't make much difference.

Austere: as far as the bounce I wasn't counting the ground and back and assuming a clearance of 1 meter for math ease. The ponit was just to demostrate that it would eventually go through by cannon.

Its silly but having shadowrunners anywhere near a Leopard tank I find to be equally silly.

That would actuall work. I believe that there is a type of commercial nanite designed to destroy structures on the molecular level. A few quintillion of those, properly modified, could eat the entire tank.

Of course, such nanites would require corporate or government connections and it would probably be simpiler to call in fire support from the most convenient Army, Navy, or Air Force.



How about the potato-in-the-exaust-pipe method? Even if the crew compartment is completely sealed there must be an opening somewhere. An engine capable of moving something as heavy as a MBT will produce a good deal of waste heat, so there must be a radiator of some sort. There is certainly a fuel tank, as well. Depending on the engine there is also an exaust port to vent waste gases.

A called shot to bypass armor isn't unreasonable; neither is jumping on the turret with a cutting laser and opening up the hatch.
mfb
i'm fairly certain that any such exhaust vents will be designed to be difficult to block. the fuel tank is going to be surrounded by some of heaviest portions of the tank's armor; if you can hit the fuel tank, you're already capable of killing the tank anyway. called shots to bypass armor shouldn't work very well, honestly. at best (house rule!), i might halve armor, or more likely multiply it by 0.75.
algcs
How much does the tank weight? What about just the turrent?
mfb
body 10, right? 60-100 tons, 75 tons average. no idea about the turret alone.

Actually, if you use the nanites "smart corrosives" with acids from M&M you could do it. It'd have to be rating 20 to pass the barrier 20 armor (or whatever the equivilant barrier of the armor is). It'd have a rating of that #, and cost of 500xthat #.

It would eat through at a rate of rating per combat turn, so thats your ticket through.
Apathy
I don't have my books with me, so I might have mis-remembered this, but don't toxic elementals with the sludge engulf power have the ability to degrade armor? If I remember it correctly, it didn't have to test against the armor rating of the vehicle.

Can anyone confirm/correct this?

Tarantula:

Hmm.

Sounds like you're on the right track.... smile.gif (Please excuse the pun. wink.gif)

I realize, from reading others' earlier posts, that the Leopard III is all but invulnerable to conventional attack (barring something on the order of a Special Atomic Demolition Munition (SADM), such as a "suitcase nuke" or atomic land mine), but what about attacking the CREW?

After all, the weakest point of any non-autonomous weapons system is/are the operator(s).

How about a series of targeted spells directed at the crew, rather than at the tank itself? I'm not clear on whether magical protections on a vehicle (barring wards, that is) would have any effect on the crew, if they were targeted specifically, rather than using a localized spell intended to effect both the crew and the tank.

A Chaos spell, or something similar, would be rather effective, I think.

Same with some illusion spells, such as Trid Phantasm.

Or possibly a combined Silence and Darkness spell (sensory deprivation, anyone? nyahnyah.gif )

As I've said before, though; I'm still a bit of a newbie, so please excuse me if I inadvertently step on any toes. smile.gif

Can't target the crew if you can't see 'em. Tinted windows are enough protection, so I'm willing to bet 20 points of composite armor works as well.

If you can convince the crew to get out of the tank, or let a mage get into the tank, then you could do it - but if you can do that, you don't need the mage, just a grenade. cool.gif

Well, chaotic world might work, briefly, considering the tank's top speed is almost 70mph. (110kph or so). Trid phantasm might make the rigger attempt some risky maneuvers if he thought he was going to crash into something like a great dragon or somesuch. Silence and darkness won't really bother any of the riggers, (i say riggers, because the tank has 2 turrets, crew of 3, 1 drives, 1 guns main gun, 1 guns other gun) and you'd best hope you're not within 20km as thats its sensor range (unless it decides to boost it with flux).

Absolutely. The exhausts vents are usually spread over a rather large area, and these days they are sometimes shielded (and will certainly be by the 2060s). Blocking them would require some kind of custom-built heat-resistant plate with heavy-duty adhesives that you'd have to attach over the exhaust area(s). And, again, you'd have to work on/around the tank for an extended period on the battlefield, make your escape, and then wait for quite some time before the engines go offline.

You can penetrate the 40 points of vehicle armor with Medium Naval and Rail Guns or heavier weapons, or with any of the heavy Surface-to-Surface or Air-to-Surface missiles found in Rigger 3. Although you're about as likely to find such weapons employed by a team of runners as you are to find suitcase nukes.
hyzmarca
Well, I was thinking more of hitting the exaust vent with a couple of AV Assault Cannon shells than blocking it. If I remember correctly, there was a big news story about combat engineers finding a way to armor the M1A1's exaust vent.
A vent has to be hollow and the grating can't be very thick. It would be the most vulnerable part of any tank. It probably wouldn't hurt the crew, but it would certainly compromise engine preformance.

Chaotic World wouldn't work on the crew because it is a direct illusion. LOS would still be required. However, Chaos and its area varient are physical spells. Tank sensors probably don't hae an OR higher than 12 so a mage casting force 6 Chaos can reasonably mess them up.

you can't target subcomponents with magic. you have to hit the whole tank, or nothing at all.

Though we could argue that about Elemental Manipulations since they follow all the standard rules for Ranged Combat, which allows for Called Shots to subcomponents on vehicle sized objects.
mfb
mmm... i'd point out the fact that such isn't mentioned in the Elemental Manipulation Spells section, in the Vehicles and Drones chapter, and say that's proof enough that called shots against vehicles don't work with elemental manips. there's room for argument, though; it never specifically disallows it.
Tarantula
Actually, it does, as it specifies external components. Considering the engine is envirosealed so that it will operate perfectly even if say, it was entirely submerged, (doesn't have amphibious, so it couldnt' go anywhere, but the engine would run) one could argue that it doesn't have a conventional external exhaust pipe. No pipe, no called shot to it.

Besides which, you'd have to overcome that lovely force 41 to affect it in the least with an elemental manip.

Frosty I have asked myself pretty much same question, What do I need on the board that can hurt anything, but will also leave cities and innocent (or not) civilians intact, and came up with the Answer. Orbital Laser Platforms. but please do take precautions and make it oh so difficult to deck into these things. Shadowrun Novel, ShadowPlay describes the Germeinschafft bank as being located at LEO, They and they alone should have the ability to utilize these weapons of not massive but definitive destruction, for a price. If I were you I'd allow the Players plenty of Play time with the Toy if they do happen to acquire one. After you think they've caused enough destruction, send warning shots, if they don't get the hint you can still take the toy out without killing the whole party, though they may lose one or two members.

Yup, the plating you see on some modern MBT (like the newest Merkavas) exhausts are not likely to be thicker than, I dunno, 1"? And if you managed to get a surprise shot at such a tank from a rear-flank angle, you could bypass the plating. In that situation, you might manage to get an AV Assault Cannon shot through the exhaust vent grating.

What you'd actually hit after that is a good question. On many designs, a straight line through the exhaust vent would continue into top or side armor, not into the engine compartment. To guarantee damage to the engine, you'd have to use a rather heavy HEAT warhead.

This problem can probably be solved adequately in the design phase of a future MBT. The actual exhaust vent can be shielded, placed along the top or rear armor plate (if on the side or back) or the side armor plate (if in the back), so that a straight line in from the exhaust vents would never end up in the engine comparments. The vents could have double shielding, on the outside and then behind a corner in the exhaust "pipe" -- the inner shields would pop up immediately if the outer shields or vent edges are hit. Or new technology could simply allow for a way to vent exhausts which require no conventional vent or pipe system, as Tarantula suggested.

In other words, I definitely wouldn't count on this method for neutralizing a 2060s MBT.

Ahhh, to kill a tank. cyber.gif biggrin.gif

Going back to the original post for a second, I have to ask, where would the rigger get it? If at the factory, congrats him on his new paperweight. Wouldn't have fuel or ammo. If at an army base, I look at you stupid and go "What? Was that their only one?" There's at least 13 other tanks in the company to shoot at him.

But as for actually killing it: Mud and/or Shape Earth for the mobility kill, then wait. Sooner or later the crew will have to come out, then snipe them. The tank as formidable weapons, as long as the engine has fuel. If you want to be cruel, use Shape Earth to dig the tank into the ground and cover it back over. Eventually the life support will run out. (Sabotage thought: Seven-7 in the life-support tanks.)

For those who want to talk about the tanks back-ups, those aren't A tank, those are an army. Hire MET2000 and leave.

I think a Fire Elemental materializing inside the tank would make life a bit unpleasant for the crew. biggrin.gif

i like the anti-personnel tank protection systems described in David Drake's tank warfare stories. basically, you ring the entire tank with proximity-fuse claymore mines at about chest level. they could even be reloaded from an internal magazine.
