Social media and online networks
Social media and online networking can be a quick and easy way to find people that you have lost touch with.
If you know someone’s full name, you may be able to search for them using social media websites such as Facebook.
Networks like Facebook often have community groups for current and former bases, battalions, units, and ships. These groups may be a valuable resource to support your search.
Additionally, there are some Armed Forces online forums which may be helpful to put you back in touch with your service friends.
