Armored money trucks

[Michael Thayne]

Are there official stats anywhere for armored vehicles of the sort used to transport large bundles of money (or diamonds etc.)? Seems like it could be very useful, both for heists as well as less conventional adventuring uses. (Prison transport for a super-strong prisoner? Not sure if that would work, would probably require armor between the cargo compartment and cab, which IDK if that type of vehicle has.)

I think something like an armored bank truck would be in the DR20-25 range. Take a standard truck, up armor it, decrease its range and handling slightly to account for the extra weight.

They typically have what's described as II/III armor, which I'm guessing is level II windows and level III in the actually armored parts. Level III armor is approximately DR 25 (stops non-AP 7.62).

IIUC level III armor in GURPS is more like DR 35 because that's what you need to reliably stop 7d damage. Typically that means 12 DR from ballistic fabric + 23 DR from plates. I think level II is 12 DR?

A cursory search didn't turn up real-world performance statistics fro such vehicles, which could be converted into GURPS terms. The Monster Hunters series has rules for up-armoring vehicles, with attendant performance penalties, but doesn't go higher than +20 DR.

GURPS always normalizes for average, but it does actually demonstrate a problem in a different area: level III also stops 5.56mmAP, which requires DR 35 or DR 25 with some hardening, or it requires the AP in tests to differ from what GURPS calls AP.

How do you figure? 5.56mm NATO ball does 5d. AP does 0.7 times as much damage, which comes to 3d+2 (2), which makes a quite perfect match for being stopped by DR 25.

Did High Tech add a new AP type? Basic only lists APHC which adds a (2) armor divisor and does not affect basic damage (a bullet that does -1/die with a (2) divisor would be perfectly reasonable but doesn't exist in GURPS that I know of).

[Rupert]

High-Tech does indeed. Normal AP rounds do x0.7 damage of one step smaller size and with (2) penetration. APHC is the good stuff with full damage and (2) penetration, and if the 5.56mm AP ammo is supposed to penetrate protection that's rated against 7.62x51mm ball, then you'd use APHC stats. If it's not supposed to penetrate that DR, then use AP and assume the people shooting are cheapskates.

[Anthony]

In that case, level III armor is DR 25 (good vs 7.62 ball at 7d and 5.56 AP at 3d+2(2)), level IV is DR 35 (good vs 7.62 AP at 5d(2)), and the armor in Basic is level IV. The flex armor should probably be DR 10 or 11, as max rated threat for IIIa is .44 magnum (3d)

Also, are you shooting for "stops all the time" (7*6) or "stops 50% of the time (7*3.5) when using 7.62mmNATO ammo?

Official GURPS DR calculations default to the latter, but many folks here on the forums seem to default to the former.
