If you are looking for mates from an old unit that you served with then take a minute to check out http://www.ComradesandColleagues.com it's genuinely free to see if your old friends are registered and only takes a minute, so it's worth a look. The site supports Australian, New Zealand, the UK and Canadian military. There are thousands of units (Squadrons, Ships, regiments etc) listed. It's well worth a look. All the best. Bob Hosking
