National Catastrophe Relief Auxiliary

The National Catastrophe Relief Auxiliary was a group dispatched a day before the the Great War, in which nurses and other medical personnel were deployed and placed on alert in the event of a catastrophe.

Pre-War
It is highly probable that the U.S government was aware of the oncoming attack, as stated in Nancy Kroydons log in the computer just outside of the Germantown Police HQ.

Post-War
Following a shortage of Prussian Blue for treatment of the effects of radiation the leader of the unit stationed at Germantown Police HQ, Nancy Kroydon, died of radiation poisoning, after which the unit fell apart. The fate of the rest of the National Catastrophe Relief Auxiliary remains a mystery, but it is likely that they fell victim to the nuclear fallout, or that they were separated and eventually integrated into the settlements that arose following the aftermath of the war.

Appearances
The National Catastrophe Relief Auxiliary is only mentioned in Fallout 3
