Carter would participate in a number of expeditions against the Comanche and other tribes in the Texas-area. It was during one of these campaigns that he was brevetted first lieutenant and awarded the Medal of Honor for his "most distinguished gallantry" against the Comanche in Blanco Canyon on a tributary of the Brazos River on October 10, 1871. He became a successful author in his later years writing several books based on his military career, including On the Border with Mackenzie (1935), as well as a series of booklets detailing his years as an Indian fighter on the Texas frontier. Carter writes: "IT IS nearly fifty years since these tragedies occurred. There are few survivors. The writer is, perhaps, the only one. This is written in the vague hope that this chronicle of the events of that period may possibly prove of some lasting and, perhaps, historical value to posterity. "The country all about the scene of these tragical events—the Texas Panhandle—was then wild, unsettled, covered with sage brush, scrub oak and chaparral, and its only inhabitants were Indians, buffalo, lobo wolves, coyotes, jack-rabbits, prairie-dogs and rattlesnakes, with here and there a few scattered herds of antelope. The railroad, that great civilizing agency, the telegraph, the telephone, and the many other marvelous inventions of man, have wrought such a wonderful transformation in our great western country that the American Indian will, if he has not already, become a race of the past, and history alone will record the remarkable deeds and strange career of an almost extinct people. With these miraculous changes has come the total extermination of the buffalo—the Indians' migratory companion and source of living—and pretty much all of the wild game that in almost countless numbers freely roamed those vast prairies. Where now the railroads girdle that country the nomadic redman lived his free and careless life and the bison thrived and roamed undisturbed at that period— where are now the appliances of modern civilization, and prosperous communities, then nothing but desolation reigned for many miles around. "In the expansion and peopling of this vast country, our little Army was most closely identified. In fact, it was the pioneer of civilization. The life was full of danger, hardships, privations, and sacrifices, little known or appreciated by the present generation. "Where populous towns, ranches and well-tilled farms, grain fields, orchards, and oil "gushers" are now located, with railroads either running through or near them, we were making trails, upon which the main roads now run, in search of hostile savages, for the purpose of punishing them or compelling them to go into the Indian reservations, and to permit the settlers, then held back by the murderous acts of these redskins, to advance and spread the civilization of the white man throughout the western tiers of counties in that far-off western panhandle of Texas."

    At 18 Greeny enlisted in the Marine Corps. Basic training misses the mark for the reality of combat. After his first kill, the significance of taking a life confuses Greeny at a raw level of guts and glory. Killing soon becomes the norm. Greeny evolves from a naive young man to an aggressive combat veteran. Then, his two best friends die in front of him. Suddenly his fight for his own survival rests on returning to a wife and new baby back in the World.
