The controlling player can move each Forward Deployment Detachment on the battlefield up to a number of inches equal to its Movement characteristic, ignoring Difficult terrain and Dangerous terrain rules. This move can the Detachment outside of its deployment zone and a Detachment can Garrison a Structure if they are able to.
