Edge of Imperial Space. Ranges

Between the main Traveller SRD and the vehicle hand book SRD we can find the following for range data

Personal Less than 1.5 meters
Close 1.5 to 3 meters
Short 3 to 12 meters
Medium 12 to 50 meters
Long 51 metres to 250 meters
Very Long 251 meters to 500 meters
Distant 501–5,000 meters
Very Distant 5,001–25,000 meters
Extreme 25,001–50,000 meters
Continental 50–500 kilometers
Orbital 501+ kilometers

Great. For a normal RPG things would have ranges given in terms of those range band. But

This Is Traveller!!!

[kick into the pit…]

So, no, ranges aren’t given that way. Ranges are given, for things other than vehicles weapons any way as Natural Attack,Melee (small blade),Melee(large blade),Thrown,Pistol,Shotgun,Assault Weapon,Rifle,Rocket. These range names are taken from various weapons in the Mercenary SRD. Of these, the only one we really have any number on is thrown, from the Mercenary SRD we can find this:

Parabolic Weapon Ranges

So what does this tell us? Other than the ranges for artillery are not based on any thing like reality in the Mercenary SRD? (A topic of another rant). Not much, other than giving use the DM’s for thrown weapons.

Now, of course, I have both dead tree and PDF version of the Traveller Main Book, so I could look them up. But…. That’s cheating. So, let’s look at some OGL options. First thing what other things are out there? Well, there is “Hyperlite: The Sirius Treaty” and there is “Worlds Apart”. Hyperlite would be the ideal source, but, despite having a copy of the OGL in their document, they don’t declare what is or isn’t Open Game Content. Bad! No cookie for you Tim Bancroft! Worlds Apart, on the other hand has this wonderful statement

All text in this work is Open Game Content, excepting the name Worlds Apart, company names, logos, artwork, and the author and artist names.

OK. From the Mercenary SRD we know that bows are either Assault Weapons or Rifles for range reasons, with the TL 1 versions being Assault weapons, the others being Rifles.

So, let’s see what bow range DM we can get.

Name Close Short Medium Long Far
Longbow -1 +0 +0 -1 -2
Shortbow -1 +0. +0 -1 N/A

Mike Cheats, looks at TMB… Fairly close, but not really.  Plus the range bands don’t really mean the same thing.   cheats some more, looks at Hyperlite Damn, even if I get a OGC statement worth having, it’s not the same either.  So, it looks like Edge is going to have it’s own range table, based on what I think are rational ranges for weapons.

So, according to the Worldwide Equipment Guide, Vol 1, Ground systems, a British .303 Cal Rifle Lee-Enfield has an effective range of 500 meters.  We will call that Rifle range.

A Russian 7.62-mm Assault Rifle AK-47/AKM has an effective range of 300 meters.  That’s sort of the default assault weapon.

The definition of effective range is “effective range – maximum range at which a weapon may be expected to achieve a high single-shot probability of hit (50%)”

So, in game terms, that means either a 7+ or 8+ to hit at those ranges.   I’m going to assume level 0 skill with the weapon, and tend toward the miss more than hit more side of the options.

So based on that data and needing to get a 8+ to hit, assuming level 0 and standard level of dexterity, we get something like this:

Weapon Type Personal Close Short Medium Long Very Long Distant
Pistol -2 0 0 -2 -4 NO NO
Shotgun -2 0 0 0 -4 NO NO
Assault Weapon -3 -1 0 0 -1 -2 -6
Rifle  NO  -1 0 0 0 -1 -2
Rocket NO NO 0 0 o 0 -2
