Eagle Guardian is a NATO regional defence scheme drawn up before 2010 to defend the Baltic states and Poland against an attack by Russia.

The plan identifies ports in Poland and Germany to receive naval assault forces, as well as British and US warships. Nine NATO divisions from the US, UK, Germany and Poland should carry out combat operations according to Article 5 of the NATO Charter in case of an armed aggression against the Baltic states or Poland.^[1]
