How many movement points a dummy have?If moves like a flight i have to decide if a dash or combat speed and at same time fill the log about this dummy flight in the way like a really flight?
A Dummy flight can have the same number of movement points as any aircraft type in the game. If you want your opponent to think it is a heavily laden A-4 strike flight, move it with the Laden A-4 movement point values. If you want your opponent to think it's a MiG-21 interceptor, move it with Clean MiG-21 movement point values.
So, yes, make a declaration about Combat or Dash speed when you are moving it, but you don't have to fill out a log entry (unless it helps you keep track of what you are pretending to have the Dummy represent!) And if you declare a dash move and don't pretend to mark off fuel in the Fuel Phase, your opponent might get suspicious that it's a dummy . . .
Another question is about cloud layers:the scenario says when i have cloud layers or this happened in automatic in each scenario?
Clouds are declared in the Scenario Conditions under Weather or occur by Scenario SSR/Random Event.
Hope this helps, and enjoy the game!
