a great implementation of a great game! Found Talon recently (although I looked at it when it was first released here on BGA, but went by for some reason, not knowing what I know now!) and am already playing several games.
One thing that might be missing from the Briefings in a mission are the Victory Conditions. Even if it is a standard "last man standing", it could be stated with a short sentence, just for completenes' sake. But Scenario 4 (Patton's End) and further ones have the Victory section listed in the Playbook separately from the Special Rules.
Kudos and keep up the good work!
