Field Shield

The Field Shield is a passive armor system that is designed to be installed by site service teams as complete systems or partial barricades. Through the use of battle proven engineering and material applications, the Field Shield Family of products can be configured to meet the demands of virtually any site location. The primary use cases were utility-scale power management and distribution networks, high-visibility public facilities, and commercial off-grid power generation sites. Each piece of the system is designed with our Patent Pending “Wave Guide Technology” which was developed to promote air flow while defeating hi power ballistic threats.

The Field Shield consists of three main components, _Sentry_Pivot, and  _Flex and boasts an expected life cycle exceeding 30+ years of active service with zero recommended maintenance requirements.
