Sealion

The act of invading Britain from the European Continent, derived from ‘Operation Sealion (Unternehmen Seelöwe)’, the failed naval invasion plan for Britain devised by Nazi Germany during World War 2. Typically used in context of grand strategy games, especially ones involving World War 2.

It looks like Germany is attempting another Sealion, but with those marine templates he isn’t going to make it.
