relatively fluid. Originally, it was composed entirely Texian Militia who came and went at will. To become an officer, a man must simply have had enough money or charisma to convince others to serve under him. In the first half of the Texas Revolution, many of the units and individual volunteers came from the United States. The United States volunteer units in the Army represented ten states; from New Orleans, Louisiana the New Orleans Greys, from Alabama the Red Rovers, Huntsville Rovers, and Mobile Greys, from Mississippi the Mississippi Guards and Natchez Mustangs, from New York the 1st New York Battalion and 2nd New York Battalion and from other states the Georgia Volunteers, Kentucky Mustangs, Missouri Invincibles, North Carolina Volunteers, and Tennessee Mounted Volunteers, and Union Guards By the end of the war, the army had grown to include three distinct divisions. Members of the regular army enlisted for two years and were subject to army discipline and the army's chain of command. A squad of permanent volunteers enlisted for the duration of the war. This group was permitted to elect its own officers, outside the oversight of the army commander-in-chief. Most of the men who joined the permanent volunteers had settled in Texas before the war had begun, both Tejano and Texians. The last unit was the volunteer auxiliary corps, comprising primarily recent arrivals from the United States who officially enlisted for a six-month term. On November 24, 1835, the Texas provisional government authorized the creation of ranging companies of rifleman. Robert "Three-legged Willie" Williamson was asked to raise three of these companies with 56 men each. Rangers were to be paid $1.25 per day.
