NCRCF Uprising

The NCR Correctional Facility Uprising was a revolt made by the Convicts of the NCR Correctional Facility against the men of the NCR who were stationed in the facility itself. All the troopers there were killed; and after the uprising the group of insurgents, renamed Powder gangers, fled to Primm, Vault 19 or remained at the Correctional Facility.

Background
When the NCR expanded eastward into Nevada they took over the old Southern Nevada Correctional Facility in Jean, and created the NCR Correctional Facility. The facility is located near train tracks that run parallel to highway I-15 and the convicts were used to maintain and expand them. As explained by Powder Gangers, no correcting was done - only manual labor. So when the majority of NCR troops guarding the facility were called away to patrol the Colorado River, the convicts decided to take things into their own hands and took over the facility using improvised weapons and explosives made from small amounts of dynamite they had stashed away.
