Suppression at Start of Scenario?

[Mobhack]

Not to my knowledge.

You could possibly do it as a saved game @ turn 1, perhaps? - but then its not on the scenario list for players to find easily or read the briefing etc.

For the human player being surprised, you could have crews away from vehicles some distance 'sleeping in a barn', and others straggling in as reinforcements. But that would not play well for the AI.
