Q: If a transport vehicle is destroyed in the same turn as it
moved flat out what happens to any embarked models? (p70)
A: They are removed as casualties.
Q: What is meant when the term ʻturnʼ is used? (p9)
A: Whenever the word turn is used it means player turn.
Otherwise it will clearly state game turn. In a complete
game turn both players get a player turn. Hence one game
turn will comprise two player turns.
so unless you took a scary amount of dangerous terrain checks while moving flat out, your units are fine.
