Integrated, Intra-Squad Radio

The Integrated, Intra-Squad Radio (IISR) is a secure handheld 2-way radio, produced by Motorola for the US Marine Corps. Its intended purpose is squad-level communications during urban warfare. The USMC has ordered 60,000 radios to be used until replaced by the more complex JTRS cluster 5 spiral 2 radio in 2013. The IISR is similar in form and function to a Motorola XTS 2500i with embedded encryption module, which was essential to provide secure voice communications, especially in war zones.

The USMC uses primarily the IISR Microphone (part# 85035-35) produced by Xacore as their radio audio accessory. The USMC has ordered 70,000 units which are a product of Canada.
