The debate shifts from cavalry in attacks to its use in plugging gaps. Mounted troops could move quickly to reinforce a threatened part of the line and fight as riflemen. The proposed alternative is infantry carried in trucks. The response distinguishes having that idea from possessing enough vehicles and infrastructure to use it, and also stresses horses' ability to cross terrain early trucks could not. The participants continue to disagree about the opportunity cost of retaining cavalry during the middle years of the war.
