The document allows you to create a hero for your faction amend his stats even give him equipment to fit a section that he was in like heavy infantry or airborne.
also included is a series of pre-made characters to add to the list in the main rulebook including the Capitolian faction's Iron Lady. A medic who previously disgusted with the deaths of a thousand soldiers due to Imperial gas attacks turned up on a heavy infantry attack to lead them to victory.
This bit of fluff is a cross reference to the piece in the main rulebook that i am referenced in.
My friend did a huge thing for me and had my likeness commissioned into a piece of art which also features the Iron Lady and Brigadier P Rist.
So now issues set in this is of the one best games I have played and has amazing miniatures i just need to paint up the factions i have already so I can get some Capitolians.
