DISTRIBUTION STATEMENT A: Approved for public release; distribution is unlimited.

1. SCOPE

1.1 Scope. This specification defines the performance requirements for the Reconnaissance Modular Helmet Kit (RMHK) communication components that will provide multiple means of communication using the Oxygen (O2) mask respirator microphone, high noise headset, handheld push-to-talk (PTT) remote, and various radios.

1.2 System Overview. The RMHK is a scalable and integratable helmet system (ballistic and non-ballistic) for use during all types and phases of parachute access and persistence operations, including transition from air insertion to all ground movement and operational requirements.

The RMHK will integrate night vision google (NVG), oxygen mask, lighting equipment, and a means of communication. The RMHK is specific for and will be fielded to reconnaissance units (Reconnaissance Battalions, Force Reconnaissance Companies) with Military Free Fall (MFF) trained parachutists.

The communications components in this specification are intended to be used as an alternative to the existing cables and interfaces in the USMC Full Spectrum Battle Equipment (FSBE) (see Diagram 1) and add additional capability (see Diagram 2). These components will allow simultaneous connection and use of the USMC Full Spectrum Battle Equipment (FSBE) Modular Integrated Communications Helmet (MICH) Maritime Communications System, respirator microphone in the USMC Parachutist’s High Altitude Oxygen System (PHAOS) mask, remote PTT (in addition to the MICH Maritime PTT), and AN/PRC-148, AN/PRC-152, or AN/PRC 152(A) radios and aircraft Intercom Systems (ICS). The intent is for the jumper to be able to communicate using a push-to-talk capability without having to remove their hands from the parachute toggles, affecting the flight of the parachute system.
