The US Navy is currently extremely overextended. They are currently losing what Navy officers have described as the largest naval battle the US has been in since WW2 against a nation whose navy consists of speedboats.
On the subject of supply or logistics, the US military basically lacks any of the transport/airlift capacity they had 25 years ago. That, to my mind, qualifies as a supply or logistics failure, given that such a capacity would be a basic necessity for any actual Army engagement in a conflict.
