The Safariland ® Linebacker is part of the Mobile Field Force product line. These products are specifically built to address communication and audio challenges law enforcement officers have faced during protests, demonstrations, and riots. The Linebacker system provides audio intelligibility in loud environments and includes a noise-canceling microphone for the clear transmittal of two-way communication. Utilizing the NATO connection, this system is compatible with existing PTTs (Push-to-Talk) or is offered as a kit for those without a PTT. The Linebacker Comms System is easily installed into the Safariland ® 906 / TR1000 Riot Helmet, ProTech® Delta Series Full Cut helmets, including the Delta 4™, and the PASGT helmet systems. It can also integrate with all other non-ballistic crowd control helmets on the market.
