The Voice Projection Unit (VPU) is an optional add-on for the Ops-Core SOTR with Microphone, built to make sure your voice is heard when it matters most. It delivers clear, powerful voice projection in loud, fast-moving environments, helping teams stay coordinated and aware even without comms.
The VPU attaches quickly to the SOTR with a simple, tool-free design, making it easy to add or remove as mission needs shift. It connects directly to standard push-to-talk (PTT) devices using the SOTR's existing microphone port and integrates seamlessly with tactical headsets. This allows operators to move instantly between projecting their voice locally and switching to secure wired communications, all while maintaining respiratory protection.
