It's the 1890s, and the Indian Wars have finally come to an end. Captain Mack Hawkins is ordered to take command of one of the first units of the recently organized U.S. Scouts. For the first time in American military history, these tribesmen are being allowed to enlist as fully-accepted soldiers in the United States Army. Hawkins' new command is the Kiowa-Comanche Detachment, and he has little time to turn his team of former nomadic prairie warriors into an efficient, disciplined fighting unit. If he doesn't, they're sure to be wiped out on their first mission of tracking down the outlaws who stole an army payroll.

At war's end, Guy Dubose—owning no skill except soldiering—joined up with the U.S. Army, donning the same Yankee blue he'd been lining up in his rifle sights for the last five bloody years. Quartered with society's lowliest at Fort Linden, the unreconstructed Rebel found himself in a whole other kind of shooting match, this time on the wild Texas frontier. But fighting was fighting, be his opponent Bluebelly or Redskin, and where the gunsmoke was the thickest was where Guy DuBose aimed to be.
For Fort Linden's commander, Captain Gordon Blackburn, however, the lives of a few insignificant Johnny Rebs was a small price to pay for a seat behind a Washington desk. Either Sergeant DuBose and his misfits would earn their captain a hero's rep—or they'd end up watering down the Texas dust with their blood!

Second Lieutenant Brad Pepperdine, a recent graduate of West Point, is assigned to a regiment of African-American soldiers participating in the brutal war against the fierce Comanche Indians. His commanding officer is hard-drinking and embittered by years of service without recognition or promotion. When a renegade band of Comanches begins raiding farms and ranches, the regiment is sent to run them down As the unit moves into combat, Pepperdine begins to understand the black soldiers as well as their Indian enemies. But most of all he learns a lot about himself. He can only desperately hope he masters what he must know before the unit is wiped out.

Captain Charles Riker had been ordered to march his company of social misfits and raw recruits deep into Sioux territory. It was a land of heat and blistering winds, where daydreaming could separate a man from his scalplock. When Indian patrols spotted the bluecoat interlopers, they set upon them with burning powder and hot lead. But when Riker and his command turn back, they find their retreat to the main body of troops cut off by the avenging Sioux.
Outnumbered by hundreds to one in a Montana wilderness where good men could be living one moment and dying the next, Riker must lead his band across long miles of open country to the nearest outpost at Tongue River. But nobody said it would be easy. They're short on rations and ammunition ... but hell, they're long on determination and guts.

Wildon Boothe was as innocent as a newborn babe when he lit out for the Arizona frontier. The band-playing military pomp of West Point did nothing to prepare the young shavetail for the man-killing wasteland of Apache Mesa. but if the Army send him to Hell itself, young Lieutenant Boothe would serve. Life on the range wasn't exactly going to be easy on his beautiful young wife, either. They'd sworn to stay hitched until death did them part. But with a marauding gang of renegade bandidos on the loose, it could be that they'd be split up sooner than either of them expected!

Guns blazed and blood spilled on the hot Arizona sand when the Apache warriors exploded from their ambush and fell upon Sergeant Terry O'Callan's squad of blue-coated troopers. This wasn't the first time O'Callan had traded hot lead with Chief Halcon's braves—and as his troopers raised sabers and broke through the Apache ranks, he knew it wouldn't be his last.

Halcon burned with a fierce hatred for the pony soldiers that rode from Fort Dawson, and vowed to take the scalp of every round-eye in the territory. And when gold is discovered on Apache land and an army of bloodthirsty prospectors armed with guns and dynamite surround the Indian village, it's Halcon's revenge against blood-crazed greed … until the brassy notes of CHARGE echo off the hills – and O'Callan must ride to glory or death for peace on the new frontier.
