As always it depends on the context.
US is currently dominant in weapons technology, Air forces ( Yes I used the plural correctly), nuclear delivery systems, submarines etc etc etc.
The US does have a manpower shortage in terms of metabolically healthy, and physically fit humans that it can draw upon for a ground war.
What are the parameters of the war they're modeling?
I actually think considerations for a ground war are pointless when considering near-peer adversaries where all sides have nuclear weapons.
