They are tasked with: 1) Security of evacuated areas and vital objects 2) Assisting - during calamities such as flooding and disease - authorities in maintaining public order - with large military transports or exercises ('Host Nation Support') - civilian authorities other military units during large events 3) Ceremonial activities Notably absent: fighting wars on foreign soil. And while training attendance is required, all work is voluntary. The National Reserve is part of the regional emergency plans so there's a real opportunity there to be part of the organised relief efforts right from the start.
