The picture above shows an example of a communications solution centred on a Headset Interface Unit (HIU).

This solution is designed to be used by firearms teams and provides a modular system giving the ability to interchange different headsets and
push-to-transmit switches to fulfil the different operational requirements.

The HIU features a shrouded PTT switch and volume control on the front of the unit, a socket mounted on the top for headsets and also a side mounted socket for the
connection of remote PTT switches. Internally the unit has a Tone Generator that allows the PTT and also remote PTT's to generate marked tones over the network for silent operation.

For Dynamic Entry and Snipers a tactical headset or Genesis headset could be used, worn with a soft hat or ballistic helmet this provides a noise-cancelling microphone and
receive earpiece.

If it is necessary to operate in a covert role then a combined microphone/inductor or neck-loop microphone/inductor is available. Used in conjunction with a covert wireless earpiece and torpedo PTT this provides a fully covert solution centred on the HIU.
