Is the Army ready for a ‘Great Power War’ against a peer competitor, in terms of maintaining and sustaining an expanded Army? If the Army had to double in size, what challenges would it encounter in maintaining and sustaining that large of a force? Over the last nine months, an interdisciplinary team of Army War College student researchers, under the direction of Dr. Tony Echevarria, have examined issues related to great power war and whether the Army is ready. One of those team members, COL H.R. Willingham, joined Dr. John R. Deni to discuss maintaining and sustaining an expanded Army.
