Re: Kingdom Rules - Used in Any Supplements?
To be sure, I think you can create your STR table to taste. In fact, the APG has just such a suggestion for character STR (p. 7), and I see no reason why one couldn't adjust the way the table scales to meet the setting or "feel" desired.
The reason I picked out the number I did was because because you can substitute "characters" for "kg" on the normal STR table and get a nice progression upwards from small units to national militaries. For example, if the Roman legions totalled roughly 50,000 troops, then their Kingdom STR would be about 50, or about 13 points out of perhaps a 300pt Kingdom (assuming Rome was at the upper end of Low Fantasy). Even a modern nation-state like the United States, assuming we field about a half million people in our armed forces (just to pick a number) pays only 27pts out of, say, 500-600 points for a STR or 105.
Now that's just infantry, but if we throw in vehicles and double our numbers with 5 more points of STR, we've still just spent only 2 more points to create a vehicle budget of roughly 12,500,000 points. If our vehicles cost (on average) about 500 points (an M1 tank is 475), then that's a fleet of roughly 25,000 vehicles more or less. Elite units would bite into that budget further. So suppose we wanted some special forces, knights, space marines, or whatever your chosen flavor of elite is. Let them be 100 points a piece instead of 25 for the poor bloody infantry, and keep 500 of them for special occasions. That's 50,000 character points allocated from (take the Roman number) 1,250,000 character points worth of infantry, and the headcount of the regular infantry shrinks by 2000 troops.
Thing is, all this is what you get if you use large STR values (we're imagining nation states, Rome, etc.), but it makes a LOT of sense to use the standard STR table for raiding bands, border skirmishes between petty kingdoms, or other small military elements because STR 1-30 covers anything from an individual squad up to a small army of 1,600 soldiers. That seems sufficiently fine-grained for lots of the kind of small unit action that involves player characters in the intrigues of border princes in a fantasy game, the petty warlords or insurgent groups in a modern game, or marauding alien fleets in a sci-fi game.
