The Falcon III radio family offers users a wide range of capabilities such as SINCGARS interoperability, APCO P25, ultra-high frequency (UHF) ground-to-ground line-of-sight communications, close-air support, programmable encryption, and access to secure IP data at on-air rates up to 5 megabits per second.

The ITT family of "SINCGARS" combat "frequency hopping" radios is currently the backbone of the Army's combat radio communications capability, and it was the primary means of communications in Iraq.

In April 2005, a civilian team in the Pentagon suggested that the SINCGARS radios, designed during the cold war to evade interception by Soviet radio scanners, be set at a single frequency, on the ground that Iraqi insurgents do not have the same signal-gathering capabilities as Warsaw Pact armies.

For example, a company team with SINCGARS radios may try to avoid detection by employing its frequency-hopping capability at a low power setting (although use of a hot loop remains an option).

SINCGARS radios offer up to eight preselected settings (manual, cue, and up to six additional preset frequencies or hopset patterns).

It is also the least secure means, although secure equipment and the ability of SINCGARS to frequency-hop provide the company team with protection against most enemy direction-finding, interception, and jamming capabilities.
