Re: Reality Check: Sniper Shots and Speed/Range Table
Reading through High Tech, it does address the issues of wind and such for precision aiming. Every +1 requires an IQ based roll at a penalty; additional penalty can be added to these rolls by the GM due to 'adverse conditions.' Any failure requires the sniper to start the process over.
Assuming perfect conditions, perfect equipment, a sniper who has spent the majority of their life doing nothing but learning how to shoot, and a sniper who has either a somewhat high IQ or very good luck (it'll probably be nice to have both), this shot has a good chance of success. |

In any case, you're still ignoring things like poor visibility as well. The longest shot on record was made in Afghanistan. Somehow, I doubt that was made in a perfectly dust-free environment. Basic suggests anywhere from -1 to -9 for poor visibility from dust or smoke (Basic p. 548), and suggests penalizing the Precision Aiming roll further for dusty conditions (or windy conditions, for that matter).

Also, I think you're discounting the probability of failing one of the Precision Aiming rolls. Remember, to claim the full +5 bonus, you have to roll 5 times, against IQ-based Guns-6. Even if we're generous, and give the sniper the same IQ as their DX, and the full penalty bought off, so they're rolling at an effective skill of 15, they still only have an 80% chance of making all the rolls, and if any roll fails, they have to start all over again! So, really, your chance of hitting (assuming an essentially windless, haze-free day), becomes only about 40%. If we assume enough wind to give -1 to the Precision Aiming rolls, (60% chance to make all the Precision Aiming rolls), it drops to 30% overall. And that's still taking into account only a torso shot, which is hardly a guaranteed kill. |

Re: Reality Check: Sniper Shots and Speed/Range Table
This matches my experience as well. Shooting with a high (or worse variable) cross-wind sucks even if you have wind flags. At that range it's even quite possible for the wind to be blowing in different directions and different speeds along the bullet's trajectory.

Re: Reality Check: Sniper Shots and Speed/Range Table
In re: the longest recorded range for a confirmed kill:
They were in the Afghan mountains. He had a spotter. He was firing a .50 with hotter than expected loads. The weather was such that they were able to use the passage whirls to aim his shots. IIRC, he used three shots to get that kill. I've made hits at 1500yds. I could *not* see the target - my spotter worked me in ith four shots. Of course, the target was stationary. |

I think that even if a DR5 armor protects, it still HT-5 tree times in a row to stop bleeding... or being saved by a doctor About precision aiming, i was saying that if you need more skill, you can keep using precision aiming, if you have a skill good enough, you don't need to, and most snipers buy the technique, so a guy with skill 15 in Guns(rifle) should have at least skill 12 in precision aiming, even if don't get the +5, he can try again, in about 10m probrably he will get the +5. And even if is just 30% chance(25% to tell the truth), it is a big chance overall, because it is much more than the record, and have 1/4 chance to break a record, it is a pretty high chance... |

High-Tech seems to assume that having the spotter doing the calculating is just as easy as doing it yourself, but is that really the case? Quote:

At a glance, I'd say being beyond the effective range of your scope (that is, the range to which it can be adjusted) gives a -2. A single crosswind is no penalty (unless it's a rather strong wind, although I'd work that as a penalty to the actual shot; see here for some ideas). Each additional crosswind would impose a -1 if blowing in the same direction as the first, -2 if blowing in the opposite direction. Strong crosswinds might impose a further penalty to Precision Aiming. EDIT: I should note that my knowledge of this shot originates from a History Channel sniper show. As said show was also guilty of stating that sniper rounds actually do more tissue damage from further away (rather, that there's a range window; closer and the round punches through without disrupting itself, farther and it doesn't pack as much punch), the information herein may similarly be suspect. They did interview the actual sniper, however, for what it's worth (it was another sniper that made the "range window" claim).

And High-Tech specifically calls for a difficulty modifier for wind in such conditions. Quote:

Again, any adverse conditions at all will reduce all these chances significantly. If you assume perfect conditions, your hypothetical skill-15 sniper (still above "professional level"), only hits half the time. I think the record is safe for a while. |
