Linthwaite won the contest: he designed a circular patch, four inches in diameters, with a solid yellow-gold background to symbolize the Cavalry heritage. On the face of the patch, he drew a stylized black tank track with a drive and idler sprockets to symbolize mobility. In the center of the track at a slight diagonal, he placed a single cannon barrel, also in black, to symbolize firepower. Finally, to symbolize the striking power of the new armored force, he added a diagonal lightning bolt in red, extending across the total design and full diameter of the patch.
