Subject: [DS2] Question About Spotting Mine Fields

I'm working on a scenario for DS which involves one side making a penetration
attack through a mine field to take a crossing point on a river. The mine
field is represented by a 3:1 mix of mine and dummy
counters.  According to the rules pre-laid mine
counters should be placed face down and only turned over once an element comes
within the 2 inches of the counter.

So the question is, should a unit be able to discover if the counter is a
dummy marker (or not) without running through the minefield?

How does it work in the Real World? Is it possible
for a non-specialist unit to discover a mine field
before they start hitting mines? Or is it possible for a VTOL to spot a
minefield?

I'll say yes, BUT.

Sure.  Surface-laid mines are visible if you know what
you're looking for and get lucky.  Tilt-rod mines are
blindingly obvious. And even buried mines have indicators. The problem comes
in noticing those indicators in combat. The other problem comes in telling
whether it's a real mine or not. I mean, are
those tilt-rods, or straightened coat hangers stuck in
the ground?

VTOLs might spot minefields, but they couldn't tell a 'dummy' field from a
live one.

It comes down to terrain, skill with which the mines
were camoflaged, emphasis put on counter-mine training
in the attacker's maneuver forces, exact type of mine, and luck.

Going by the rest of your description (and after looking at the rules again)
it would seem that an engineer unit would be needed to determine for sure if a
mine field was live or not (and to make disarming attempt if it was live).

I think it is sufficient to model the other types of discovery just by have a
counter on the table in the first place.

Thanks for the insight, JF

The send a few civies into the minefield to see if it's real or not could
result in a number of false positives.

Easily solved. Send more civilians. If it's not real, you'll find out; if it
is real, well, you were going to clear it anyway.

Engineer-speak.

Density = # mines per meter of front.

PE = Probability of Encounter. The odds that a tank driving a straight line
through the minefield would hit a mine. 1 in 4 real:dummy ratio means that for
a minefield one row of counters thick, you'd have a.25 PE which in my book
counts as little worse than a
phony minefield anyway.  I'd breach it in-stride using
maneuver elements.

> Going by the rest of your description (and after

No, anyone can tell if it's live. Only engineers can do so safely (ie from a
distance).

Also note that it would be breaching, not disarming. Disarming is for EOD
types. We breach.

> I think it is sufficient to model the other types of

True, that.
