Default Striker Book 1 Rule 1 B Distance and Book 3 ranges

Evening all,

Striker Book 3 DS 2 K states that a weapon's direct fire range can't exceed the capability of the direct fire control system. The CPR Direct Fire ranges are in centimeters and the Direct FC ranges are in kilometers.

Book 1 Rule B Distance states that 1 cm = 10 meters. In book 3 the CPR Direct Fire Range Table on DST page the range is in centimeters and the Direct FC Table has range in kilometers.

At TL 9 the CPR gun Direct fire effective range is 100 cm.

Using the distance rule of 1 cm = 10 m the TL 9 effective range is 1,000 meters or 1 km.

A TL 9 Direct FC system's effective range is 2.5 km = 2,500 m, and in Striker's distance scale per Book 1 is 250 cm.

A TL 9 CPR gun with the effective range of 100 cm is well within the capabilities of a TL 9 Direct FC system of 2.5 km effective range if my calculations are correct, which I'm hoping they are.

In the purest technical sense, the CPR direct fire range CAN exceed the range of fire control - the round's just flying out beyond your ability to control where it hits, so everything past the range of your fire control is utterly pointless. In the case of large caliber CPR guns with low-tech fire control, you can end up with a situation in which you're doing effective range penetration [for a KEAP round, say] at extreme range odds of hitting, then lose everything past that - though the round still packs punch - because you can't lay it on a target with any hope of hitting.

On the reverse, in the case of high-tech fire control on low-caliber guns, it's possible to have a direct fire control that far outranges the range of the CPR gun. In that case ... honestly, I'm not sure. One interpretation is that your effective, long, and extreme range damage are all within effective range odds of hitting - and then the round peters out and hits the ground before reaching your fire control's long range. Another (and more likely) interpretation is that the round itself suffers increasing inaccuracy as it loses power, so that even though you're within the fire control's effective range, the round's odds of hitting at the gun's long and extreme range are reduced - one should therefore endeavor to have the fire control not exceed the gun's range, because the extra would be wasted.

Clarifying: the effective range of a TL 9 low velocity gun, or a TL 9 medium velocity gun firing a round other than a KEAP or KEAPER round, as given by the Direct Fire Range table on page 8 of the Design Sequence table. A KEAP or KEAPER round fired from a TL 9 medium velocity gun would have an effective range of 1500 meters.

Yup. Your calculations are correct.

Evening Carlobrand,

Thanks for the clarifications and confirming I conversion is on track. For the record I realize the the ranges are modified by gun type and KEAP/KEAPER rounds. My example was kept simple to make things easier on me.

While working on DS 5 MD guns I have determined that the KEAP/KEAPER Direct Fire Ranges are still out to lunch for DS 2, DS 3, and DS 4. I some how got the idea that the KEAP/KEAPER penetration values where the direct range values.

Again thanks for the catch earlier about the KEAP/KEAPER ranges being out of whack.

Morning all,

Another update on the KEAP/KEAPER direct fire ranges.

First off DS 4 doesn't require a direct fire range listing, if I've got the sequence down, being an indirect fire system and doesn't have direct fire ranges. If I'm right then DS 4 doesn't have an issue.

DS 2 direct fire ranges matched the ones provided in the example and DS 3 AC ranges were the only ones out to lunch. The correction for the KEAP/KEAPER can be found in the Striker DS 2 CPR gun test thread.

Thanks again to all who have provided feedback.
