Three men, including two British soldiers, have been charged under terror laws with being members of a banned neo-Nazi group.
Alexander Deakin, 22, Mikko Vehvilainen, 32, and Mark Barrett, 24, have been charged with being members of National Action.
It was the first far-right group to be banned by the Home Office in 2016.
They are among five men arrested on 5 September. Two others have since been released without charge.
Deakin from Birmingham, Vehvilainen based at Sennybridge Camp in Brecon, and Barrett, based at Dhekelia Garrison in Cyprus, will appear at Westminster Magistrates' Court on Tuesday.
West Midlands Police has said the arrests were "pre-planned and intelligence-led" with no threat to public safety..
