Hi there. Me and a mate are trying to contact a friend of ours. He was based in Bosnia until March of this year before transferring units and heading to the province of Helmand, Afghanistan. I haven't heard from him since then, and have sent a number of emails etc as has my mate. Unforunately he did not say which unit he had transferred to, but he was a member of the Welsh guards beforehand. However, I do have his service number and was wondering if it is possible for to trace someone using only these details? If so, if anyone could provide a number/website/contact details in order for us to be able to trace him, we'd be very grateful. Unfortunately, we have no contact for his family. Thanks in advance for your help!
