As an engineer - one of the five GDF classes - we snuck forwards under covering fire to help build the bridge. Each class has a special function - the engineer, for instance, can repair vehicles, set up gun turrets and complete objectives like bridge building. The strength of Quake Wars is that each objective needs a specific class to complete it, stressing team-play - with soldiers giving covering fire to engineers while special ops take out long range targets - as the only successful way to win.
