I already know enough about this, I just want to see what the Military Bronies know about...

Operation: Fortitude

General info: Predates Operation: Overlord

Begin...!

746047
Inflatable Tanks! Inflatable Tanks for days!

746086

Hmm... How about the "Ducks"? Those were sweet...

It was a fake force massing north of Normandy , trying to fake out the germans if I'm not mistaken

746292 It was actually a diversion tactic that was created just to increase the possibility of Overlord's success. But yes, they basically made an entire artificial army, trucks, planes, they even built fake bases and fed the Germans false information to have them think that they were attacking some port city 200 miles up the coast from Omaha.

I think I remember something with Sherman tank boats
