A Bollard is a short vertical post, usable as a traffic control barrier. They are used throughout heavy industry and in commercial building management to protect assets and usually consist of a simple steel posts, either anchored to concrete, cored into a hard surface, buried in the ground, secured on a Self-locking Taper, or Impact Recovery System protecting the surrounding foundations from damage when a bollard is impacted.
Bollards are a retractable barricade featured in Battlefield 4 and were first seen on Siege of Shanghai. They ca= be activated by at least one control switch positioned nearby and are sturdy enough to easily stop a Main Battle Tank.
Bollards return in Battlefield Hardline, functioning in a manner similar to their Battlefield 4 counterparts.
