Does interdiction apply at night? I could not find where it says that it does not.
Do you have the latest rule set?
Look at 11.2 Interdiction last sentence of 2nd paragraph at the top of Pg 17.
"The marker on the Air Interdiction Track identifies the effect on German movement on that map for both the German Movement and Mechanized Movement phases during the AM and PM turns."
Does not say it effects movement at Night.
