You know, I was thinking...we’ve gone from operation names picked roughly at random or for some reason of sly humor by generals (Operation Torch, Operation Linebacker, Operation Mincemeat) to names picked by a PR department (Operation Just Cause, Operation Enduring Freedom) to an operation name that sounds like the name an eight year old picked for her stuffed unicorn toy: Odyssey Dawn.
Heck, even Carter did better than this. Operation Eagle Claw...now that’s a name! Too bad the actual operation was a cluster.
Since this is a war chosen by women, my guess is the name came from a woman with Honda minivan named Dawn.
