Show security is a must in my line of work, and the above photo provides a good example of a commonly used tool in the pursuit of minimizing threat. The tactic used here is a purposely located, or created, choke point on which to engage the enemy on favorable terms. In this instance, the 50 Cal gun was foregone in favor of the lighter and more mobile 240B, which fires a 7.62 belt fed round, and is highly effective in neutralizing targets at up to 500 yards. The raised nest provides added observation advantage, as well as improved line of fire in the event of such a need. Perfect for deterrence and real threat engagement, be it for the large national show or the small tailgater.
