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, at about $1300 a piece, 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 Talkabout
handheld radio, however, it features more secure communications.
The chosen radio was based on the Motorola XTS 2500i with embedded encryption module, which was essential to provide secure voice communications, especially in war zones.
