Jet Pack and Dodge Bonuses

Has anyone created speed modifiers?

I would volunteer, but I'm somewhat at a loss a to where to begin.

A lot of games do have a hindrance both to shooter and/or to the target if they're moving.

Adding in the rule for jetpacks (using basically Tupteq's modifiers posted above, which my group seems to be okay with) makes me now consider whether it might make sense to implement:

-1D if the shooter is moving significantly (more than 10 meters per round)

-1D if the target is moving significantly (more than 10 meters per round)

How about adding the target's movement penalty to the shooter's difficulty (IE 2 moves = 1 MAP or 1d difficulty)?

Then you'd have to factor in scale to that

Well watching many war movies, the size of fighters in relation to people and the speed they move is usually a null addition (their speed negates teh bonus of their size), if not a negative cause we rarely see lots of hits from ground weapons to fighters.

We are still talking about jet packs, right?

When shooting at a moving target, there are a couple different ways to approach this.

You can "lead" the target, moving the weapon with the target and following through with that movement as you pull the trigger. This method is often used in skeet shooting.

Or, if you can predict a future location of the target (it's moving in a straight line across your field of fire, for example), you can just "camp" the cross hairs on a spot you know (or suspect) the target will soon be, and time the shot so that it gets there at the same time.

In real world applications, a bullet leaves the muzzle of a rifle at around 3,000 feet per second. Pistols are generally sub-sonic, in the 600-1200 feet per second range... so the "timing" of the shot is not that difficult to calculate, unless you're dealing with vast distances that would render the target beyond the reach of the naked eye. So, at typical skirmish distances, unless you want a very specific target (the brain stem or the right knee or some such), just placing the sights on the target will result in a hit.

At jet pack speeds, I would tend to allow some variance, though. Since jet packs are really fast, I might allow the jet packer to claim a full dodge, since at the speeds I'm thinking of, he wouldn't be able to do anything else anyway.

As for the stormies getting a bonus on attack rolls to hit moving targets, it would seem to me that this bonus is intended to offset some preexisting penalty (or, bonus received by the target) for speed. Where a description of such a penalty (or bonus) might be is unknown to me... Confused

My group liked this, and we were ready to move forward with the list as proposed. Then we were going to add some penalties for the jet pack wearing character when they were shooting.

But then one of my players pointed out that such a character would already be getting a MAP, so such a penalty would be pretty severe.

Then when I was typing this out, and incorporaing our own new penalty for moving characters (both as a target and as a shooter), I realized that such a rule also doubles up the penalty from the chart.

So instead here are both rules, working in tandem:

Movement during Combat
When combatants are moving, the following penalties apply:

Shooter is moving more than 10 meters per round: -1D
Target is moving more than 10 meters per round: -1D

In addition, if the target is moving exceptionally fast (often via a jet pack or rocket pack), the following numbers are added to the difficulty:

Target is moving 40-79 meters per round: +3
Target is moving 80-159 meters per round: +6
Target is moving 160 meters or more per round: +9
