Nice preview. The artwork looks OK. It reminds me a lot of some of the artwork in the GURPS 4th edition books. The page boarders (if one insists on having them) are fairly unobtrusive as well. The text reads well. All up it looks very promising.
Now shall I get really an@l (and only joking)?
"mm" is the abbreviation for millimetre which, as for all Système International d'Unités, should be separated from the numbers by a space. Thus, it should be "200 mm", not "200mm".

Many people don't realise this, especially for degrees Centigrade or Fahrenheit.
The "middlemen" (plural) is mentioned and then the "middleman's" singular.
The text speaks of the "Republicans" and "Federals" but then switches to the "rebels". We assume that means the Republicans, but consistency....
Why not use "km" instead of "kilometres"?
"indig rebels" I'm assuming is colloquial for indigenous rebels?
