Use
River Crossing
Like other bridges, its main purpose is to allow infantry and land vehicles to cross it. It is wide enough to accommodate one vehicle. Naval vehicles cannot pass under it.
When destroyed neither vehicle nor infantry can cross it.
Destroying it can be used to block the enemy's logistics routes.
Defensive Position
The small nooks on each side of the bridge can serve as cover for crouched infantry, making them safe from enemy vehicles trying to run them over.
A few types of defensive structures can be built on most bridges: Sandbags, Tank Trap, Barbed Wire, deployed Tripod, Fire Pit.
