invasion route
Enemy's entry path
An invasion route is a path or corridor through which military forces enter hostile territory.
The term emphasizes geography and strategy—mountain passes, river valleys, and coastal approaches that armies have used throughout history: The Fulda Gap was considered a likely invasion route into Western Europe.
Figuratively, any pathway that allows unwanted entry: The respiratory tract is the primary invasion route for airborne pathogens.
