Live post 1921 service record search facility

The MOD continues to hold all service records where the individual had a discharge date of post 1921, these total around 10 million records, with about 500,000 having seen service in World War 1. Subject to access to the database that supports the MOD’s main archive, an assisted search facility will be offered that will in many cases enable confirmation of whether the MOD holds a record for an individual.
