checkpoint, place it where drivers cannot see the

turnoffs. When using a roadblock to close off a road,
place it at an intersection to let drivers change to
another route with little delay.

the roadblock with automatic weapons. Ensure that
defensive positions—
• Include a fighting position for the crew-served

• Have fields of fire that cover the approaches to
the roadblock to keep it from being breached.
• Are not accessible to an attacker and provide
cover and concealment.

change to another route with little delay.
