> You wrote: You started it--now I get to pontificate! > I'd imagine anti-armour mines would be more of a problem for walkers We'd be seeing the development of an intermediate class of mines. Real anti-tank mines will have to be directed energy to deal with Grav, GEV, and simply real tough undersides. A simple blast mine has a hard time doing anything more than popping tracks nowdays (unless some dumbass drives over it in a BRDM, in which case he deserves to cook). These will be, with proper materials (and I am no expert on this, but some of ya'll seem to be), non-metallic. Already we are at the point where only two items need to be metallic--the firing pin and plate. The plate is real cooker--the explosive just sets the plate in motion and it slams through the floor of the tank, ruining the day of anyone inside. I'm willing to be a non-ferrous substitute could be found, maybe even a ceramic? A lot of AT mines do without it, but they can't K-Kill tanks, just M-Kill. Firing pin is no sweat to make non-metallic, again, a good ceramic. The problem, as I see it, comes if you want to include neato sensors or IFF in it. Then we'd need non-metallic electronic components, including radio antennas. I am not qualified to have an opinion on the feasability of this in the future. I can say that mines such as the TC-6 series (Italian, liscence built by Egypt) have 2.86g of metal in the 6kg mine, the steel striker tip. If the sensitivity on your metal detector is low enough to detect, the background noise is going to set it off nearly constantly. But it becomes much easier with their electronics package allowing remote activation/deactivation. This is why, in me house rules, I'm deliberately pointing out that these are NOT metal detectors, but Ground Peneterating Radars, IRs, chemical sniffers, and God Alone knows what else.. True AP will either be area effect (M-16&-18 series) or derivations of the 'Toe Popper' M-14. To have the ooph to effect PA, Walkers, and other light armored vehicles will be beyond the toe poppers, but the area effect ones might do so at close range. You could also have a straight "Heavy AP" or "Light AT" blast mine mixed in with your AP and AT mines. My bet is that they would be called Light AT in keeping with the current political idiodicy associated with "Anti-Personell Mines".

I'm not saying it's impossible, but I just think that the signal to noise ratio would be extremely low.

Unless they've got AHDs, of course. Easy to find, mark and clear.

Stealth manufacturers will then find another way to keep their craft hidden. I don't think mines will be 'stealthed' against gravity detection or other sensors. I think they will be made in whatever way is cheapest. After all, they're used in quantity and are disposable. Therefore, employing expensive stealth measures is counterproductive to sales. Would you buy one stealth mine, or 1000 mines that can be easily located when time is taken? After all the purpose of mines isn't to kill people or vehicles. They're there to injure people and immobilise tanks. They're there to slow or block an advance through the minefield. One stealth mine can only injure one or two squads, or immobilise one tank at most. The remainder can carry on and come to no harm. The position is over run. Therefore the expensive stealth mine is ineffective! 1000 mines that are easily located. Well, the infantry platoon stops as their leading guys get shredded, the tank platoon comes to a halt as their tracks are blown away. Both platoons realise they're in a mine field and retreat. Mine disposal engineers are brought up, and check their gravity gradiometers, metal detectors, magnetic anomaly detectors, ground penetrating radars, thermal vision and other sensors. Their computers correlate all the info, together with the historical satellite photos, and the conclusion is that there is about 990 mines, located there, there, there and there! An hour or two later, the engineers have carefully cleared the mine field. The attack proceeds several hours later. The minefield has stopped many times it's own value in enemy equipment and personnel, used up time, and consumed mine disposal resources. Also, mine manufacturers would be concerned about future disposability. They would be actively looking for ways that their mines could be easily located and disposed of. Why? Think of lawsuits by civilians! Even though these mines would be easily located and easily disposed of, they would be dangerous in their active state and take some time to disable and dispose of them. One could quite easily imagine future mines that emit a creaking noise and a flash of firefly light every 100 seconds, being powered, say, by heat changes from day to night. This would keep civilians and most animals away. Every one knows that the minefield is there.

Realistically, in a system which gives a rat's ass about the troops, minefields will have to be either breached or bypassed. My vision of of future warfare involves relatively small units spread over relatively large areas. You can't waste the troops clearing mines the Russian way, and you will often have the option to bypass.

The minefield has stopped many But throw a couple of 'stealth' mines into that mix, and they will slow down even more, as a presumed 'cleared' area erupts in their face. John Atkinson once shared the opinion of a commander that suggested that there would be fewer casualties in the end by just plowing through the minefield, rather than trying to remove it (but I believe that was trying to remove it under fire). I'm not sure this idea will remain true with the ever-increasing lethality of mines. I fall into the category of those who believe that mines are best described by their role - Anti-personnel, anti-armor, etc. and then say, as many here have - 1) there are mines with these game capabilities.... 2) There are detection systems with these capabilities.... Discussions like this one could be useful for fiction writers, but the game should remain abstracted to preserve playability. IMHO anyway...

The function of a mine field is to stop infantry (AP) or Tanks (AT) or both (AT/AP), until engineers can be brought up. The mine is an expendable piece of ordinance much like a bullet. The ultimate stealth mine field is a fence and large, clearly marked signs, marked "Danger: Minefield!" with no mines. It's extremely cheap and stops infantry and tanks.

on standard DSII minefield costs. No stealth - DSII standard rules
apply. Stealth mines can only be placed before game starts, not during game.
Each stealth minefield marker purchased comes with a hidden marker. Place the
hidden marker on top of the mine marker, so that the mine marker is hidden.
Place the two markers together where you desire on the table.
If a non-engineer element/unit attempts to cross a stealth
minefield, inflict appropriate damage and the unit carries on, after making
appropriate confidence checks for under fire, damage etc. Note that the unit
doesn't necessarily stop as the unit may not realize that it's in a stealth
minefield! Particularly if it takes no damage!
> Detection equipment will be in three levels, basic, enhanced, superior.
Assume that engineers and engineering vehicles carry appropriate detection
equipment automatically and at no extra points cost. For engineers to detect a
stealth minefield, engineers nominate a hidden marker nearby (withing 2"),
they roll unit quality dice vs leadership rating for each engineer element
within 2" of the hidden mine marker. Opponent rolls minefield stealth rating.
If the Engineers roll higher than opponent, the hidden marker is removed. The
engineers can work on removing the minefield in their next activation.
Dummy minefields: Available at the rate of one per minefield purchased,
whether stealth or regular. For example, buy four minefield markers, get up to
four dummy markers. Hide the dummy and real minefield markers from your
opponent and carefully place the dummy and minefield markers as you desire on
the battlefield, upside down. Your opponent knows that the minefields are
there but can't be sure whether they're real or not as they are carefully
marked for all to see.
Any non-engineer unit that wants to cross the dummy/real minefield
has
to make a confidence check to proceed. TL+0, say? Failure means losing
confidence levels. Success allows crossing. Crossing the minefield causes the
marker to be flipped. If it's dummy, it is removed. If it's real, inflict
standard minefield damage on the unit.
Any comments, suggestions, improvements, etc?
