Use the pull downs to select the kinds of Main Characters, Vehicles, and Weapons you want to generate. You can select the kind of weapon the unattached Main Characters are carrying or let the computer generate some. When you press the Generate button, the record sheet shows up in the bottom window.
If you don't like the first round of generation, click the Clear button and then press Generate again.
When it is done generating stuff, you can cut and paste it into Word. You still have to transfer it by hand to the record sheet, but that still saves LOTS of time.
