The timeline is a unique way of navigating the history of the Aux Units. It allows you to visually map important Aux events and decisions with general WW2 events. See just how ahead or behind Hitler we really were.
You can also listen to audio relating to some stories, watch video and click through to web links.
The timeline is still fairly new technology and will be developed with new content being added all the time.
