Re: High Amounts of non penetrating damage. Bullets VS Plate Carriers
In Low-tech, there's a box on p. 102 named Blunt Trauma and Edged Weapons which might be relevant for this discussion too. It says that it's incredibly hard for a blade to cut through armor, so optionally, treat cutting damage as crushing unless the damage exceeds twice the DR of the armor.
The same could maybe be done with high-tech armor and high velocity projectiles to solve the problem Anthony and Ulzgoroth were talking about; if the attack doesn't exceed the DR by much, the damage is BABT and converted to crushing. This seems a pretty RAW way to do it, considering the LT-box. |

Which would pretty dramatically change how such armour works in GURPS, it will also lead to some odd situations: For instance given how over penetration normally caps Pi damage by HP, having it convert to Cr could lead to more damage being inflicted instantly in some cases! With up to 25 points of Cr damage you also get some serious knock back Last edited by Tomsdad; 05-08-2017 at 07:12 AM. |

But anyway, if the number seems excessive, make it crushing for up to 1\2 DR for piercing attacks perhaps. |

Yep there's an over-penetration rule in High Tech for Torsos (basically injury is maxed at HP, but still counts at full value for Bleeding etc). It stops high energy rifle bullets taking people to -1xHP or worse in one shot instantly. Bullet wounds even from high energy rounds don't really work that way unless they hit some pretty specific things. Quote:
I'm going to try Anthony's half and half suggestion with my allowing blunt trauma to counts as Cr for knock down tests, and see how it goes Last edited by Tomsdad; 05-08-2017 at 07:37 AM. |

That isn't entirely unrealistic, although extremely unlikely. Because the armor completely stops the bullet, that means the armor+body must absorb all of the bullet's momentum, instead of just the portion represented with blowthrough. However, you basically need some fantasy material that gives way more DR against piercing than crushing (even Kevlar only has a 4x difference, which isn't enough to see the effect). Say you have DR 60/5 (60 vs pi, 5 vs cr). A piercing attack is capped at 10 HP injury, so with the 1/3 divisor (suggested in the linked thread, and also my previous post in this one) you reach that with a 45 damage piercing attack against the above armor (45 pi becomes 15 cr, which becomes 10 injury when DR is subtracted). Anything between 48 (11 HP injury) and 60 (15 HP injury) thus does a bit more injury.

Look at the kind of knock-back you'd be getting here, and what that would mean for firing a gun that did that with Newtons 3rd law in action. |

Fair enough, I'm far, far from an expert and just went with gameablity, so I'll concede :) Might still try it in my own games tho, see how it works out, maybe cap the damage at even less, just a few points or so. |

*Higher than average damage with a firearm doesn't mean a more powerful bullet, it means hitting a higher-value target, impacting at a better angle, or similar.

However, level IV armor is rated to stop 7.62mm AP, and while there are no specific standards for resistance to weaker threats other than they also have to not get through, there's not really a plausible design for plates that suffers the same deformation against 5.56mm as it would against 7.62. |
