This video is an intro to SFB (Star Fleet Battles) which is a combat simulator.
This vid will cover Cadet Scenario #3 Move and Fire
Scenarios 1-4 are pretty simple. Note this is an older video using version 10 of the sfb cadet module. The module as of this posting is version 21 ( or 2.1) Many things have changed including what the page on the vassal web site looks like.
