"The battle-line is where the Infantry is"... On every war map the extent of progress is shown by the location of the Infantry. The function of all other combat troops—Air Force, Armored Force, Artillery—is to help prepare the way for the Infantry. These tough fighters must seize, mop up, and press on, or the ground is not won. As the Infantry moves—so moves the battle-line. [Newsmap, U.S. War Department, Volume III, No. 8BD.]
