Here's a video that's probably old news to some, but recounts the story of a Lynx and Gazelle trying to find and destroy and Iraqi tank during the invasion of Basra. The Gazelle is used in an observation role and isn't mentioned much (the Lynx is the focus) but it covers some tactics and is generally interesting, hopefully (note, the uploader has made a mistake and refers to the Apache, it's not.)
