Gold Almost took all objectives took substantial casualties doing so
Juno Took all objectives and faced serious casualties doing so
Sword Couldn't take Caen until a full month later
Omaha Nearly called a failure. Largest amount of casualties. Offsetting this is that arguably facing the most battle hardened Germany troops (352nd) as opposed to the OST troops at other landing sites. Achieved objectives at D Day +3. Still better performance than Sword beach.
Utah Achieved virtually all objectives with little casualties (but arguably not as much opposition as Juno)
Performance ranking: 1. Canadien 2. USA 3. British
