Ok.. heres a chance to pick the day we make the first move on Iraq.
Qualifiers... No small unit skirmishes like our recon forces now on the ground. To qualify, It must be the start of formal 'hostilities', such as the Air Raids on Command and Control we kicked the Air War off with last time.
Items to consider.. phase of the moon, weather, tidal conditions, muslim holidays, status and condition of readyness of US forces, nature of forces, etc.
Make your best guess...
Good luck!
