I'm interested in building a "take and defend a bridgehead" tactical scenario but I honestly do not know if (i) there are any significant road bridges in Arma 3 or (ii) if any such bridges can be destroyed in such a way as to prevent passage across an otherwise un-traversable area, i.e. a true bridge or a viaduct. There's no point making a bridgehead mission if the bridge is either indestructable or can easily be circumvented by troops and vehicles. I'm not holding my breath, I don't think Arma has ever modelled environmental destruction in this tactical way but if I'm wrong I'd love to know, otherwise it's back to "destroy this AA battery", "occupy this village", "eliminate all enemies" or "rescue that hostage" when what I really want to use as a mission goal is is to cut off or defend an avenue of mobility. Thank you!
